wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: All Graphviz attributes are specified by name-value pairs. Thus, to wolffd@0: set the fillcolor of a node abc, one would use wolffd@0: wolffd@0: wolffd@0: abc [fillcolor = red] wolffd@0: wolffd@0: wolffd@0: Similarly, to set the arrowhead style of an edge abc -> def, wolffd@0: one would use wolffd@0: wolffd@0: wolffd@0: abc -> def [arrowhead = diamond] wolffd@0: wolffd@0: wolffd@0: Further details concerning the setting of attributes can be found wolffd@0: in the description of the wolffd@0: DOT language. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: At present, most device-independent units are either inches or wolffd@0: points, wolffd@0: which we take as 72 points per inch. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Some attributes, such as wolffd@0: dir or arrowtail, are wolffd@0: ambiguous when used in wolffd@0: DOT wolffd@0: with an undirected graph since the head and tail of an edge are meaningless. wolffd@0: As a convention, the first time an undirected edge appears, the wolffd@0: DOT wolffd@0: parser will assign the left node as the tail node and the right node as wolffd@0: the head. For example, the edge A -- B will have tail A wolffd@0: and head B. It is the user's responsibility to handle such wolffd@0: edges consistently. If the edge appears later, in the format wolffd@0: wolffd@0: wolffd@0: B -- A [taillabel = "tail"] wolffd@0: wolffd@0: wolffd@0: the drawing will attach the tail label to node A. wolffd@0: To avoid possible confusion when such attributes are required, the user wolffd@0: is encouraged to use a directed graph. wolffd@0: If it is important to make the graph appear undirected, this can be wolffd@0: done using the dir, arrowtail wolffd@0: or arrowhead attributes. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: For undirected edges T -- H;, one of the nodes, usually wolffd@0: the righthand one, is treated as the head for the purpose of wolffd@0: interpreting forward and back. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: String allowing escape sequences which are replaced according wolffd@0: to the context. wolffd@0: For node attributes, the substring \N is replaced by the name of the node, wolffd@0: and the substring \G by the name of the graph. wolffd@0: For graph or cluster attributes, the substring \G is replaced by the wolffd@0: name of the graph or cluster. wolffd@0: For edge attributes, the substring \E is replaced by the name of the edge, wolffd@0: the substring \G is replaced by the name of the graph or cluster, wolffd@0: and the substrings \T and \H by the names of wolffd@0: the tail and head nodes, respectively. wolffd@0: The name of an edge is the string formed from the name of the wolffd@0: tail node, the appropriate edge operator (-- or ->) and the name of the wolffd@0: head node. wolffd@0: wolffd@0: wolffd@0: In addition, if the associated attribute is wolffd@0: label, wolffd@0: headlabel or taillabel, wolffd@0: the escape sequences \n, \l and \r wolffd@0: divide the label into lines, centered, left-justified, and right-justified, wolffd@0: respectively. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: These specify the order in which nodes and edges are drawn in concrete wolffd@0: output. The default breadthfirst is the simplest, but when the graph wolffd@0: layout does not avoid edge-node overlap, this mode will sometimes have wolffd@0: edges drawn over nodes and sometimes on top of nodes. If the mode wolffd@0: nodesfirst is chosen, all nodes are drawn first, followed by the wolffd@0: edges. This guarantees an edge-node overlap will not be mistaken for wolffd@0: an edge ending at a node. On the other hand, usually for aesthetic wolffd@0: reasons, it may be desirable that all edges appear beneath nodes, even wolffd@0: if the resulting drawing is ambiguous. This can be achieved by choosing wolffd@0: edgesfirst. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: These specify the granularity of packing connected components when wolffd@0: the pack attribute is true. A value of node causes wolffd@0: packing at the node and edge label, with no overlapping of these objects. wolffd@0: This produces a layout with the least area, but it also allows interleaving, wolffd@0: where a node of one component may lie between two nodes in another wolffd@0: component. A value of graph does a packing using the bounding box of the wolffd@0: component. Thus, there will be a rectangular region around a component wolffd@0: free of elements of any other component. wolffd@0: A value of clust guarantees that top-level clusters are kept intact. wolffd@0: What effect a value has also depends on the layout algorithm. For wolffd@0: example, neato does not support clusters, so a value of clust will wolffd@0: have the same effect as the default node value. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: These specify the 8 row or column major orders for traversing a wolffd@0: rectangular array, the first character corresponding to the major wolffd@0: order and the second to the minor order. Thus, for "BL", the wolffd@0: major order is from bottom to top, and the minor order is from left wolffd@0: to right. This means the bottom row is traversed first, from left wolffd@0: to right, then the next row up, from left to right, and so on, wolffd@0: until the topmost row is traversed. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: List of pointf, separated by spaces. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Corresponding to directed graphs drawn wolffd@0: from top to bottom, from left to right, from bottom to top, and from wolffd@0: right to left, respectively. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Factor damping force motions. On each iteration, a nodes movement wolffd@0: is limited to this factor of its potential motion. By being less than wolffd@0: 1.0, the system tends to "cool", thereby preventing cycling. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Spring constant used in virtual physical model. It roughly corresponds wolffd@0: to an ideal edge length (in inches), in that increasing K tends to wolffd@0: increase the distance between nodes. wolffd@0: Note that the edge attribute len can be used to wolffd@0: override this value for adjacent nodes. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Hyperlinks incorporated into device-dependent output. wolffd@0: At present, used in ps2, cmap, i*map and svg formats. wolffd@0: For all these formats, URLs can be attached to nodes, edges and wolffd@0: clusters. URL attributes can also be attached to the root graph in ps2, wolffd@0: cmap and i*map formats. This serves as the base URL for relative URLs in the wolffd@0: former, and as the default image map file in the latter. wolffd@0: wolffd@0: wolffd@0: For svg, cmapx and imap output, the active area for a node is its wolffd@0: visible image. wolffd@0: For example, an unfilled node with no drawn boundary will only be active on its label. wolffd@0: For other output, the active area is its bounding box. wolffd@0: The active area for a cluster is its bounding box. wolffd@0: For edges, the active areas are small circles where the edge contacts its head wolffd@0: and tail nodes. In addition, for svg, cmapx and imap, the active area wolffd@0: includes a thin polygon approximating the edge. The circles may wolffd@0: overlap the related node, and the edge URL dominates. wolffd@0: If the edge has a label, this will also be active. wolffd@0: Finally, if the edge has a head or tail label, this will also be active. wolffd@0: wolffd@0: wolffd@0: Note that, for edges, the attributes headURL, wolffd@0: tailURL, labelURL and wolffd@0: edgeURL allow control of various parts of an wolffd@0: edge. Also note that, if active areas of two edges overlap, it is unspecified wolffd@0: which area dominates. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Style of arrowhead on the head node of an edge. wolffd@0: See also the dir attribute, wolffd@0: and the undirected note. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Multiplicative scale factor for arrowheads. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Style of arrowhead on the tail node of an edge. wolffd@0: See also the dir attribute, wolffd@0: and the undirected note. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Bounding box of drawing in integer points. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: When attached to the root graph, this color is used as the background for wolffd@0: entire canvas. When a cluster attribute, it is used as the initial wolffd@0: background for the cluster. If a cluster has a filled wolffd@0: style, the wolffd@0: cluster's fillcolor will overlay the wolffd@0: background color. wolffd@0: wolffd@0: wolffd@0: If no background color is specified for the root graph, no graphics wolffd@0: operation are performed on the background. This works fine for wolffd@0: PostScript but for bitmap output, all bits are initialized to something. wolffd@0: This means that when the bitmap output is included in some other wolffd@0: document, all of the bits within the bitmap's bounding box will be wolffd@0: set, overwriting whatever color or graphics where already on the page. wolffd@0: If this effect is not desired, and you only want to set bits explicitly wolffd@0: assigned in drawing the graph, set bgcolor="transparent". wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, the drawing is centered in the output canvas. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Specifies the character encoding used when interpreting string input wolffd@0: as a text label. The default value is UTF-8. wolffd@0: The other legal value is iso-8859-1 or, wolffd@0: equivalently, wolffd@0: Latin1. The charset attribute is case-insensitive. wolffd@0: Note that if the character encoding used in the input does not wolffd@0: match the charset value, the resulting output may be very strange. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Mode used for handling clusters. If clusterrank is local, a wolffd@0: subgraph whose name begins with "cluster" is given special treatment. wolffd@0: The subgraph is laid out separately, and then integrated as a unit into wolffd@0: its parent graph, with a bounding rectangle drawn about it. wolffd@0: If the cluster has a label parameter, this label wolffd@0: is displayed within the rectangle. wolffd@0: Note also that there can be clusters within clusters. wolffd@0: At present, the modes global and none wolffd@0: appear to be identical, both turning off the special cluster processing. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Basic drawing color for graphics, not text. For the latter, use the wolffd@0: fontcolor attribute. wolffd@0: wolffd@0: wolffd@0: For edges, the value wolffd@0: can either be a single color or a colorList. wolffd@0: In the latter case, the edge is drawn using parallel splines or lines, wolffd@0: one for each color in the list, in the order given. wolffd@0: The head arrow, if any, is drawn using the first color in the list, wolffd@0: and the tail arrow, if any, the second color. This supports the common wolffd@0: case of drawing opposing edges, but using parallel splines instead of wolffd@0: separately routed multiedges. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: This attribute specifies a color scheme namespace. If defined, it specifies wolffd@0: the context for interpreting color names. In particular, if a wolffd@0: color value has form xxx or //xxx, wolffd@0: then the color xxx will be evaluated according to the current color scheme. wolffd@0: If no color scheme is set, the standard X11 naming is used. wolffd@0: For example, if colorscheme=bugn9, then color=7 wolffd@0: is interpreted as /bugn9/7. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Comments are inserted into output. Device-dependent. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, allow edges between clusters. (See lhead and ltail below.) wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, use edge concentrators. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If false, the edge is not used in ranking the nodes. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, attach edge label to edge by a 2-segment wolffd@0: polyline, underlining the label, then going to the closest point of spline. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: This specifies the distance between nodes in separate connected wolffd@0: components. If set too small, connected components may overlap. wolffd@0: Only applicable if pack=false. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Set the number of dimensions used for the layout. The maximum value wolffd@0: allowed is 10. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Set edge type for drawing arrowheads. This indicates which ends of the wolffd@0: edge should be decorated with an arrowhead. The actual style of the wolffd@0: arrowhead can be specified using the arrowhead wolffd@0: and arrowtail attributes. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Only valid when mode="ipsep". wolffd@0: If true, constraints are generated for each edge in the largest (heuristic) wolffd@0: directed acyclic subgraph such that the edge must point downwards. wolffd@0: If hier, generates level constraints similar to those used with wolffd@0: mode="hier". The main difference is that, in the latter wolffd@0: case, only these constraints are involved, so a faster solver can be used. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Distortion factor for shape=polygon. wolffd@0: Positive values cause top part to wolffd@0: be larger than bottom; negative values do the opposite. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: This specifies the expected number of pixels per inch on a display device. wolffd@0: For bitmap output, this guarantees that text rendering will be wolffd@0: done more accurately, both in size and in placement. For SVG output, wolffd@0: it is used to guarantee that the dimensions in the output correspond to wolffd@0: the correct number of points or inches. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If edgeURL is defined, this is the link used for the non-label wolffd@0: parts of an edge. This value overrides any URL wolffd@0: defined for the edge. wolffd@0: Also, this value is used near the head or tail node unless overridden wolffd@0: by a headURL or tailURL value, wolffd@0: respectively. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Synonym for edgeURL. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If the edge has a URL or edgeURL wolffd@0: attribute, this attribute determines which window of the wolffd@0: browser is used wolffd@0: for the URL attached to the non-label part of the edge. wolffd@0: Setting it to "_graphviz" will open a new window if it wolffd@0: doesn't already exist, or reuse it if it does. wolffd@0: If undefined, the value of the target is used. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Tooltip annotation attached to the non-label part of an edge. wolffd@0: This is used only if the edge has a URL wolffd@0: or edgeURL attribute. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Terminating condition. If the length squared of all energy gradients are wolffd@0: < epsilon, the algorithm stops. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Fraction to increase polygons (multiply wolffd@0: coordinates by 1 + esep) for purposes of spline edge routing. wolffd@0: This should normally be strictly less than wolffd@0: sep. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Color used to fill the background of a node or cluster wolffd@0: assuming style=filled. wolffd@0: If fillcolor is not defined, color is wolffd@0: used. (For clusters, if color is not defined, wolffd@0: bgcolor is used.) If this is not defined, wolffd@0: the default is used, except for wolffd@0: shape=point or when the output wolffd@0: format is MIF, wolffd@0: which use black by default. wolffd@0: wolffd@0: wolffd@0: Note that a cluster inherits the root graph's attributes if defined. wolffd@0: Thus, if the root graph has defined a fillcolor, this will override a wolffd@0: color or bgcolor attribute set for the cluster. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, the node size is specified by the values of the wolffd@0: width wolffd@0: and height attributes only wolffd@0: and is not expanded to contain the text label. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Color used for text. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Font used for text. This very much depends on the output format and, for wolffd@0: non-bitmap output such as PostScript or SVG, the availability of the font wolffd@0: when the graph is displayed or printed. As such, it is best to rely on wolffd@0: font faces that are generally available, such as Times-Roman, Helvetica or wolffd@0: Courier. wolffd@0: wolffd@0: wolffd@0: If Graphviz was built using the wolffd@0: fontconfig library, the latter library wolffd@0: will be used to search for the font. However, if the fontname string wolffd@0: contains a slash character "/", it is treated as a pathname for the font wolffd@0: file, though font lookup will append the usual font suffixes. wolffd@0: wolffd@0: wolffd@0: If Graphviz does not use fontconfig, fontname will be wolffd@0: considered the name of a Type 1 or True Type font file. wolffd@0: If you specify fontname=schlbk, the tool will look for a wolffd@0: file named schlbk.ttf or schlbk.pfa or schlbk.pfb wolffd@0: in one of the directories specified by wolffd@0: the fontpath attribute. wolffd@0: The lookup does support various aliases for the common fonts. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Allows user control of how basic fontnames are represented in SVG output. wolffd@0: If fontnames is undefined or svg, wolffd@0: the output will try to use known SVG fontnames. For example, the wolffd@0: default font Times-Roman will be mapped to the wolffd@0: basic SVG font serif. This can be overridden by setting wolffd@0: fontnames to ps or gd. wolffd@0: In the former case, known PostScript font names such as wolffd@0: Times-Roman will be used in the output. wolffd@0: In the latter case, the fontconfig font conventions wolffd@0: are used. Thus, Times-Roman would be treated as wolffd@0: Nimbus Roman No9 L. These last two options are useful wolffd@0: with SVG viewers that support these richer fontname spaces. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Directory list used by libgd to search for bitmap fonts if Graphviz wolffd@0: was not built with the fontconfig library. wolffd@0: If fontpath is not set, the environment wolffd@0: variable DOTFONTPATH is checked. wolffd@0: If that is not set, GDFONTPATH is checked. wolffd@0: If not set, libgd uses its compiled-in font path. wolffd@0: Note that fontpath is an attribute of the root graph. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Font size, in points, used for text. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If the end points of an edge belong to the same group, i.e., have the wolffd@0: same group attribute, parameters are set to avoid crossings and keep wolffd@0: the edges straight. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If headURL is defined, it is wolffd@0: output as part of the head label of the edge. wolffd@0: Also, this value is used near the head node, overriding any wolffd@0: URL value. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, the head of an edge is clipped to the boundary of the head node; wolffd@0: otherwise, the end of the edge goes to the center of the node, or the wolffd@0: center of a port, if applicable. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Synonym for headURL. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Text label to be placed near head of edge. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Indicates where on the head node to attach the head of the edge. wolffd@0: In the default case, the edge is aimed towards the center of the node, wolffd@0: and then clipped at the node boundary. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If the edge has a headURL, wolffd@0: this attribute determines which window of the wolffd@0: browser is used wolffd@0: for the URL. Setting it to "_graphviz" will open a new window if it wolffd@0: doesn't already exist, or reuse it if it does. wolffd@0: If undefined, the value of the target is used. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Tooltip annotation attached to the head of an edge. This is used only wolffd@0: if the edge has a headURL attribute. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Height of node, in inches. This is taken as the initial, minimum height wolffd@0: of the node. If fixedsize is true, this wolffd@0: will be the final height of the node. Otherwise, if the node label wolffd@0: requires more height to fit, the node's height will be increased to wolffd@0: contain the label. Note also that, if the output format is dot, the wolffd@0: value given to height will be the final value. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Synonym for URL. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Gives the name of a file containing an image to be displayed inside wolffd@0: a node. The image file must be in one of the recognized formats, wolffd@0: typically JPEG, PNG, GIF or Postscript, and be able to be converted wolffd@0: into the desired output format. wolffd@0: wolffd@0: wolffd@0: Unlike with the shapefile attribute, wolffd@0: the image is treated as node wolffd@0: content rather than the entire node. In particular, an image can wolffd@0: be contained in a node of any shape, not just a rectangle. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Attribute controlling how an image fills its wolffd@0: containing node. In general, the image is given its natural size, wolffd@0: (cf. dpi), wolffd@0: and the node size is made large enough to contain its image, its wolffd@0: label, its margin, and its peripheries. wolffd@0: Its width and height will also be at least as large as its wolffd@0: minimum width and height. wolffd@0: If, however, fixedsize=true, wolffd@0: the width and height attributes specify the exact size of the node. wolffd@0: wolffd@0: wolffd@0: During rendering, in the default case (imagescale=false), wolffd@0: the image retains its natural size. wolffd@0: If true, wolffd@0: the image is uniformly scaled (i.e., its aspect ratio is wolffd@0: preserved) to fit inside the node. wolffd@0: At least one dimension of the image will be as large as possible wolffd@0: given the size of the node. wolffd@0: When width, wolffd@0: the width of the image is scaled to fill the node width. wolffd@0: The corresponding property holds when imagescale=height. wolffd@0: When both, wolffd@0: both the height and the width are scaled separately to fill the node. wolffd@0: wolffd@0: wolffd@0: In all cases, if a dimension of the image is larger than the wolffd@0: corresponding dimension of the node, that dimension of the wolffd@0: image is scaled down to fit the node. As with the case of wolffd@0: expansion, if imagescale=true, width and height are wolffd@0: scaled uniformly. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Text label attached to objects. wolffd@0: If a node's shape is record, then the label can wolffd@0: have a special format wolffd@0: which describes the record layout. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If labelURL is defined, this is the link used for the label wolffd@0: of an edge. This value overrides any URL wolffd@0: defined for the edge. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: This, along with labeldistance, determine wolffd@0: where the wolffd@0: headlabel (taillabel) are placed with respect to the head (tail) wolffd@0: in polar coordinates. The origin in the coordinate system is wolffd@0: the point where the edge touches the node. The ray of 0 degrees wolffd@0: goes from the origin back along the edge, parallel to the edge wolffd@0: at the origin. wolffd@0: wolffd@0: wolffd@0: The angle, in degrees, specifies the rotation from the 0 degree ray, wolffd@0: with positive angles moving counterclockwise and negative angles wolffd@0: moving clockwise. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Multiplicative scaling factor adjusting the distance that wolffd@0: the headlabel (taillabel) is from the head (tail) node. wolffd@0: The default distance is 10 points. See labelangle wolffd@0: for more details. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, allows edge labels to be less constrained in position. wolffd@0: In particular, it may appear on top of other edges. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Color used for headlabel and taillabel. wolffd@0: If not set, defaults to edge's fontcolor. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Font used for headlabel and taillabel. wolffd@0: If not set, defaults to edge's fontname. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Font size, in points, used for headlabel and taillabel. wolffd@0: If not set, defaults to edge's fontsize. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Synonym for labelURL. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Justification for cluster labels. If r, the label wolffd@0: is right-justified within bounding rectangle; if l, left-justified; wolffd@0: else the label is centered. wolffd@0: Note that a subgraph inherits attributes from its parent. Thus, if wolffd@0: the root graph sets labeljust to l, the subgraph inherits wolffd@0: this value. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Top/bottom placement of graph and cluster labels. wolffd@0: If the attribute is t, place label at the top; wolffd@0: if the attribute is b, place label at the bottom. wolffd@0: By default, root wolffd@0: graph labels go on the bottom and cluster labels go on the top. wolffd@0: Note that a subgraph inherits attributes from its parent. Thus, if wolffd@0: the root graph sets labelloc to b, the subgraph inherits wolffd@0: this value. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If the edge has a URL or labelURL wolffd@0: attribute, this attribute determines which window of the wolffd@0: browser is used wolffd@0: for the URL attached to the label. wolffd@0: Setting it to "_graphviz" will open a new window if it wolffd@0: doesn't already exist, or reuse it if it does. wolffd@0: If undefined, the value of the target is used. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Tooltip annotation attached to label of an edge. wolffd@0: This is used only if the edge has a URL wolffd@0: or labelURL attribute. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, the graph is rendered in landscape mode. Synonymous with wolffd@0: rotate=90 or wolffd@0: orientation=landscape. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Specifies layers in which the node or edge is present. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Specifies a linearly ordered list of layer names attached to the graph wolffd@0: The graph is then output in separate layers. Only those components wolffd@0: belonging to the current output layer appear. For more information, wolffd@0: see the page How to use drawing layers (overlays). wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Specifies the separator characters used to split the wolffd@0: layers attribute into a list of layer names. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Preferred edge length, in inches. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Specifies strictness of level constraints in neato wolffd@0: when mode="ipsep" or "hier". wolffd@0: Larger positive values mean stricter constraints, which demand more wolffd@0: separation between levels. On the other hand, negative values will relax wolffd@0: the constraints by allowing some overlap between the levels. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Logical head of an edge. When compound is true, wolffd@0: if lhead is defined and is the name of a cluster containing wolffd@0: the real head, wolffd@0: the edge is clipped to the boundary of the cluster. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Label position, in points. wolffd@0: The position indicates the center of the label. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Logical tail of an edge. When compound is true, wolffd@0: if ltail is defined and is the name of a cluster wolffd@0: containing the real tail, wolffd@0: the edge is clipped to the boundary of the cluster. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: For graphs, this sets x and y margins of canvas, in inches. If the margin wolffd@0: is a single double, both margins are set equal to the given value. wolffd@0: wolffd@0: wolffd@0: Note that the margin is not part of the drawing but just empty space wolffd@0: left around the drawing. It basically corresponds to a translation of wolffd@0: drawing, as would be necessary to center a drawing on a page. Nothing wolffd@0: is actually drawn in the margin. To actually extend the background of wolffd@0: a drawing, see the pad attribute. wolffd@0: wolffd@0: wolffd@0: For nodes, this attribute specifies space left around the node's label. wolffd@0: By default, the value is 0.11,0.055. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Sets the number of iterations used. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Multiplicative scale factor used to alter the MinQuit (default = 8) wolffd@0: and MaxIter (default = 24) parameters used during crossing wolffd@0: minimization. These correspond to the wolffd@0: number of tries without improvement before quitting and the wolffd@0: maximum number of iterations in each pass. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Specifies the minimum separation between all nodes. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Minimum edge length (rank difference between head and tail). wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Technique for optimizing the layout. If mode is major, wolffd@0: neato uses stress majorization. If mode is KK, wolffd@0: neato uses a version of the gradient descent method. The only advantage wolffd@0: to the latter technique is that it is sometimes appreciably faster for wolffd@0: small (number of nodes < 100) graphs. A significant disadvantage is that wolffd@0: it may cycle. wolffd@0: wolffd@0: wolffd@0: There are two new, experimental modes in neato, hier, which adds a top-down wolffd@0: directionality similar to the layout used in dot, and ipsep, which wolffd@0: allows the graph to specify minimum vertical and horizontal distances wolffd@0: between nodes. (See the sep attribute.) wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: This value specifies how the distance matrix is computed for the input wolffd@0: graph. The distance matrix specifies the ideal distance between every wolffd@0: pair of nodes. neato attemps to find a layout which best achieves wolffd@0: these distances. By default, it uses the length of the shortest path, wolffd@0: where the length of each edge is given by its len wolffd@0: attribute. If model is circuit, neato uses the wolffd@0: circuit resistance wolffd@0: model to compute the distances. This tends to emphasize clusters. If wolffd@0: model is subset, neato uses the subset model. This sets the wolffd@0: edge length to be the number of nodes that are neighbors of exactly one wolffd@0: of the end points, and then calculates the shortest paths. This helps wolffd@0: to separate nodes with high degree. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If Graphviz is built with MOSEK defined, mode=ipsep and mosek=true, wolffd@0: the Mosek software (www.mosek.com) is use to solve the ipsep constraints. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Minimum space between two adjacent nodes in the same rank, in inches. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: By default, the justification of multi-line labels is done within the wolffd@0: largest context that makes sense. Thus, in the label of a polygonal wolffd@0: node, a left-justified line will align with the left side of the node wolffd@0: (shifted by the prescribed margin). wolffd@0: In record nodes, left-justified wolffd@0: line will line up with the left side of the enclosing column of fields. wolffd@0: If nojustify is true, multi-line labels will be justified wolffd@0: in the context of itself. For example, if the attribute is set, wolffd@0: the first label line is long, and the second is shorter and left-justified, wolffd@0: the second will align with the left-most character in the first line, wolffd@0: regardless of how large the node might be. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If set, normalize coordinates of final wolffd@0: layout so that the first point is at the origin, and then rotate the wolffd@0: layout so that the first edge is horizontal. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Used to set number of iterations in wolffd@0: network simplex applications, used in wolffd@0: computing node x coordinates. wolffd@0: If defined, # iterations = nslimit * # nodes; wolffd@0: otherwise, # iterations = MAXINT. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Used to set number of iterations in wolffd@0: network simplex applications, used for ranking nodes. wolffd@0: If defined, # iterations = nslimit1 * # nodes; wolffd@0: otherwise, # iterations = MAXINT. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If "out" for a graph G, and n is a node in G, then edges n->* appear wolffd@0: left-to-right in the same order in which they are defined. wolffd@0: If "in", the edges *->n appear wolffd@0: left-to-right in the same order in which they are defined for all wolffd@0: nodes n. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Specify order in which nodes and edges are drawn. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Determines if and how node overlaps should be removed. Nodes are first wolffd@0: enlarged using the sep attribute. wolffd@0: If true, overlaps are retained. wolffd@0: If the value is scale, overlaps are removed by uniformly scaling in x and y. wolffd@0: If the value converts to false, node overlaps are removed by a wolffd@0: Voronoi-based technique. wolffd@0: If the value is scalexy, x and y are separately wolffd@0: scaled to remove overlaps. wolffd@0: If the value is orthoxy or orthoyx, overlaps wolffd@0: are moved by optimizing two constraint problems, one for the x axis and wolffd@0: one for the y. The suffix indicates which axis is processed first. wolffd@0: If the value is ortho, the technique is similar to orthoxy except a wolffd@0: heuristic is used to reduce the bias between the two passes. wolffd@0: If the value is ortho_yx, the technique is the same as ortho, except wolffd@0: the roles of x and y are reversed. wolffd@0: The values portho, porthoxy, porthoxy, and portho_yx are similar wolffd@0: to the previous four, except only pseudo-orthogonal ordering is wolffd@0: enforced. wolffd@0: wolffd@0: wolffd@0: If the value is compress, the layout will be scaled down as much as wolffd@0: possible without introducing any overlaps, obviously assuming there are wolffd@0: none to begin with. wolffd@0: wolffd@0: wolffd@0: If the value is ipsep, and the layout is done by neato with wolffd@0: mode="ipsep", the overlap removal constraints are wolffd@0: incorporated into the layout algorithm itself. wolffd@0: N.B. At present, this only supports one level of clustering. wolffd@0: wolffd@0: wolffd@0: If the value is vpsc, overlap removal is similarly to ortho, except wolffd@0: quadratic optimization is used to minimize node displacement. wolffd@0: N.B. At present, this mode only works when mode="ipsep". wolffd@0: wolffd@0: wolffd@0: Except for fdp, the layouts assume overlap="true" as the default. wolffd@0: Fdp first uses a number of passes using built-in, force-directed technique wolffd@0: to remove overlaps. Thus, fdp accepts overlap with an integer wolffd@0: prefix followed by a colon, specifying the number of tries. If there is wolffd@0: no prefix, no initial tries will be performed. If there is nothing following wolffd@0: a colon, none of the above methods will be attempted. By default, fdp wolffd@0: uses overlap="9:portho". Note that overlap="true", wolffd@0: overlap="0:true" and overlap="0:" all turn off all overlap wolffd@0: removal. wolffd@0: wolffd@0: wolffd@0: Except for the Voronoi method, all of these transforms preserve the wolffd@0: orthogonal ordering of the original layout. That is, if the x coordinates wolffd@0: of two nodes are originally the same, they will remain the same, and if wolffd@0: the x coordinate of one node is originally less than the x coordinate of wolffd@0: another, this relation will still hold in the transformed layout. The wolffd@0: similar properties hold for the y coordinates. wolffd@0: This is not quite true for the "porth*" cases. For these, orthogonal wolffd@0: ordering is only preserved among nodes related by an edge. wolffd@0: wolffd@0: wolffd@0: NOTEThe methods orthoxy and orthoyx are still evolving. The semantics of these may change, or these methods may disappear altogether. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: This is true if the value of pack is true (case-insensitive) or a wolffd@0: non-negative integer. If true, each connected component of the graph is wolffd@0: laid out separately, and then the graphs are packed tightly. wolffd@0: If pack has an integral value, this is used as the size, wolffd@0: in points, of wolffd@0: a margin around each part; otherwise, a default margin of 8 is used. wolffd@0: If pack is interpreted as false, the entire graph is laid out together. wolffd@0: The granularity and method of packing is influenced by the wolffd@0: packmode attribute. wolffd@0: wolffd@0: wolffd@0: For layouts which always do packing, such a twopi, the pack wolffd@0: attribute is just used to set the margin. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: This indicates the granularity and method used for packing wolffd@0: (cf. packMode). Note that defining wolffd@0: packmode will automatically turn on packing as though one had wolffd@0: set pack=true. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: The pad attribute specifies how much, in inches, to extend the wolffd@0: drawing area around the minimal area needed to draw the graph. wolffd@0: If the pad is a single double, both the x and y pad values are set wolffd@0: equal to the given value. This area is part of the wolffd@0: drawing and will be filled with the background color, if appropriate. wolffd@0: wolffd@0: wolffd@0: Normally, a small pad is used for aesthetic reasons, especially when wolffd@0: a background color is used, to avoid having nodes and edges abutting wolffd@0: the boundary of the drawn region. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Width and height of output pages, in inches. If this is set and is wolffd@0: smaller than the size of the layout, a rectangular array of pages of wolffd@0: the specified page size is overlaid on the layout, with origins wolffd@0: aligned in the lower-left corner, thereby partitioning the layout wolffd@0: into pages. The pages are then produced one at a time, in wolffd@0: pagedir order. wolffd@0: wolffd@0: wolffd@0: At present, this only works for PostScript output. For other types of wolffd@0: output, one should use another tool to split the output into multiple wolffd@0: output files. Or use the viewport to generate wolffd@0: multiple files. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If the page attribute is set and applicable, wolffd@0: this attribute specifies the order in which the pages are emitted. wolffd@0: This is limited to one of the 8 row or column major orders. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Color used to draw the bounding box around a cluster. wolffd@0: If pencolor is not defined, color is wolffd@0: used. If this is not defined, bgcolor is used. wolffd@0: If this is not defined, the default is used. wolffd@0: wolffd@0: wolffd@0: Note that a cluster inherits the root graph's attributes if defined. wolffd@0: Thus, if the root graph has defined a pencolor, this will override a wolffd@0: color or bgcolor attribute set for the cluster. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Set number of peripheries used in polygonal shapes and cluster wolffd@0: boundaries. Note that wolffd@0: user-defined shapes are treated as a wolffd@0: form of box shape, so the default wolffd@0: peripheries value is 1 and the user-defined shape will be drawn in wolffd@0: a bounding rectangle. Setting peripheries=0 will turn this off. wolffd@0: Also, 1 is the maximum peripheries value for clusters. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true and the node has a pos attribute on input, neato prevents the wolffd@0: node from moving from the input position. This property can also be specified wolffd@0: in the pos attribute itself (cf. the point type). wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Position of node, or spline control points. wolffd@0: For nodes, the position indicates the center of the node. wolffd@0: On output, the coordinates are in points. wolffd@0: wolffd@0: wolffd@0: In neato and fdp, pos can be used to set the initial position of a node. wolffd@0: By default, the coordinates are assumed to be in inches. However, the wolffd@0: -s command line flag can be used to specify wolffd@0: different units. wolffd@0: wolffd@0: wolffd@0: When the -n command line flag is used with wolffd@0: neato, it is assumed the positions have been set by one of the layout wolffd@0: programs, and are therefore in points. Thus, neato -n can accept wolffd@0: input correctly without requiring a -s flag and, in fact, wolffd@0: ignores any such flag. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If quantum > 0.0, node label dimensions wolffd@0: will be rounded to integral multiples of the quantum. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Rank constraints on the nodes in a subgraph. wolffd@0: If same, all nodes are placed on the same rank. wolffd@0: If min, all nodes are placed on the minimum rank. wolffd@0: If source, all nodes are placed on the minimum rank, and wolffd@0: the only nodes on the minimum rank belong to some subgraph whose wolffd@0: rank attribute is "source" or "min". wolffd@0: Analogous criteria hold for rank=max and rank=sink. wolffd@0: (Note: the wolffd@0: minimum rank is topmost or leftmost, and the maximum rank is bottommost wolffd@0: or rightmost.) wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Sets direction of graph layout. For example, if rankdir="LR", wolffd@0: and barring cycles, an edge T -> H; will go wolffd@0: from left to right. By default, graphs are laid out from top to bottom. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: In dot, this gives the desired rank separation, in inches. This is wolffd@0: the minimum vertical distance between the bottom of the nodes in one wolffd@0: rank and the tops of nodes in the next. If the value wolffd@0: contains "equally", the centers of all ranks are spaced equally apart. wolffd@0: Note that both wolffd@0: settings are possible, e.g., ranksep = "1.2 equally". wolffd@0: In twopi, specifies radial separation of concentric circles. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Sets the aspect ratio (drawing height/drawing width) for the drawing. wolffd@0: Note that this is adjusted before wolffd@0: the size attribute constraints are enforced. wolffd@0: wolffd@0: wolffd@0: If ratio is numeric, it is taken as the desired aspect ratio. wolffd@0: Then, if the actual aspect ratio is less than the desired ratio, wolffd@0: the drawing height is scaled up to achieve the wolffd@0: desired ratio; if the actual ratio is greater than that desired ratio, wolffd@0: the drawing width is scaled up. wolffd@0: wolffd@0: wolffd@0: If ratio = fill and the size wolffd@0: attribute is set, node positions are scaled, separately in both x wolffd@0: and y, so that the final drawing exactly fills the specified size. wolffd@0: wolffd@0: wolffd@0: If ratio = compress and the size wolffd@0: attribute is set, dot attempts to compress the initial layout to fit wolffd@0: in the given size. This achieves a tighter packing of nodes but wolffd@0: reduces the balance and symmetry. This feature only works in dot. wolffd@0: wolffd@0: wolffd@0: If ratio = expand, the size wolffd@0: attribute is set, and both the width and the height of the graph are wolffd@0: less than the value in size, node positions are scaled wolffd@0: uniformly until at least wolffd@0: one dimension fits size exactly. wolffd@0: Note that this is distinct from using size as the wolffd@0: desired size, as here the drawing is expanded before edges are generated and wolffd@0: all node and text sizes remain unchanged. wolffd@0: wolffd@0: wolffd@0: If ratio = auto, the page wolffd@0: attribute is set and the graph cannot be drawn on a single page, wolffd@0: then size is set to an ``ideal'' value. wolffd@0: In particular, the size in a given dimension will be the smallest integral wolffd@0: multiple of the page size in that dimension which is at least half the wolffd@0: current size. The two dimensions are then scaled independently to the wolffd@0: new size. This feature only works in dot. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Rectangles for fields of records, in points. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, force polygon to be regular. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true and there are multiple clusters, run cross wolffd@0: minimization a second time. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: This is a synonym for the dpi attribute. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: This specifies nodes to be used as the center of the wolffd@0: layout and the root of the generated spanning tree. As a graph attribute, wolffd@0: this gives the name of the node. As a node attribute (circo only), it wolffd@0: specifies that the node should be used as a central node. In twopi, wolffd@0: this will actually be the central node. In circo, the block containing wolffd@0: the node will be central in the drawing of its connected component. wolffd@0: If not defined, wolffd@0: twopi will pick a most central node, and circo will pick a random node. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If 90, set drawing orientation to landscape. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Edges with the same head and the same samehead value are aimed wolffd@0: at the same point on the head. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Edges with the same tail and the same sametail value are aimed wolffd@0: at the same point on the tail. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If the input graph defines the vertices wolffd@0: attribute, and output is dot or xdot, this gives wolffd@0: the number of points used for a node whose shape is a circle or ellipse. wolffd@0: It plays the same role in neato, when adjusting the layout to avoid wolffd@0: overlapping nodes, and in image maps. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: During network simplex, maximum number of edges with negative cut values wolffd@0: to search when looking for one with minimum cut value. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Fraction to increase polygons (multiply wolffd@0: coordinates by 1 + sep) for purposes of determining overlap. Guarantees wolffd@0: a minimal non-zero distance between nodes. wolffd@0: If unset but esep is defined, sep will be wolffd@0: set to esep/0.8. If esep is unset, the default value wolffd@0: is used. wolffd@0: wolffd@0: wolffd@0: When overlap="ipsep" or "vpsc", wolffd@0: sep gives a minimum distance, in inches, to be left between nodes. wolffd@0: In this case, if sep is a pointf, the x and y separations can be wolffd@0: specified separately. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Set the shape of a node. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: (Deprecated) If defined, shapefile specifies a file containing user-supplied node content. wolffd@0: The shape of the node is set to box. wolffd@0: The image in the shapefile must be wolffd@0: rectangular. The image formats supported as well as the precise semantics of wolffd@0: how the file is used depends on the wolffd@0: output format. For further details, see wolffd@0: External PostScript files. wolffd@0: wolffd@0: wolffd@0: There is one exception to this usage. wolffd@0: If shape is set to "epsf", shapefile gives wolffd@0: a filename containing a definition of the node in PostScript. wolffd@0: The graphics defined must be contain all of the wolffd@0: node content, including any desired boundaries. wolffd@0: For further details, see wolffd@0: wolffd@0: External PostScript files. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Print guide boxes in PostScript at the beginning of wolffd@0: routesplines if 1, or at the end if 2. (Debugging) wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Number of sides if shape=polygon. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Maximum width and height of drawing, in inches. wolffd@0: If defined and the drawing is too large, the drawing is uniformly wolffd@0: scaled down so that it fits within the given size. wolffd@0: wolffd@0: wolffd@0: If size ends in an exclamation point (!), wolffd@0: then it is taken to be wolffd@0: the desired size. In this case, if both dimensions of the drawing are wolffd@0: less than size, the drawing is scaled up uniformly until at wolffd@0: least one dimension equals its dimension in size. wolffd@0: wolffd@0: wolffd@0: Note that there is some interaction between the size and wolffd@0: ratio attributes. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Skew factor for shape=polygon. Positive values wolffd@0: skew top of polygon to right; negative to left. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Controls how, and if, edges are represented. If true, edges are drawn as wolffd@0: splines routed around nodes; if false, edges are drawn as line segments. wolffd@0: If set to "", no edges are drawn at all. wolffd@0: wolffd@0: wolffd@0: (1 March 2007) The values line and spline can be wolffd@0: used as synonyms for false and true, respectively. wolffd@0: In addition, the value polyline specifies that edges should be wolffd@0: drawn as polylines. wolffd@0: wolffd@0: wolffd@0: By default, the attribute is unset. How this is interpreted depends on wolffd@0: the layout. For dot, the default is to draw edges as splines. For all wolffd@0: other layouts, the default is to draw edges as line segments. Note that wolffd@0: for these latter layouts, if splines="true", this wolffd@0: requires non-overlapping nodes (cf. overlap). wolffd@0: If fdp is used for layout and splines="compound", then the edges are wolffd@0: drawn to avoid clusters as well as nodes. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Parameter used to determine the initial layout of nodes. If unset, the wolffd@0: nodes are randomly placed in a unit square with wolffd@0: the same seed is always used for the random number generator, so the wolffd@0: initial placement is repeatable. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Set style for node or edge. For cluster subgraph, if "filled", the wolffd@0: cluster box's background is filled. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: A URL or pathname specifying an XML style sheet, used in SVG output. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If tailURL is defined, it is wolffd@0: output as part of the tail label of the edge. wolffd@0: Also, this value is used near the tail node, overriding any wolffd@0: URL value. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If true, the tail of an edge is clipped to the boundary of the tail node; wolffd@0: otherwise, the end of the edge goes to the center of the node, or the wolffd@0: center of a port, if applicable. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Synonym for tailURL. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Text label to be placed near tail of edge. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Indicates where on the tail node to attach the tail of the edge. wolffd@0: See undirected. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If the edge has a tailURL, wolffd@0: this attribute determines which window of the wolffd@0: browser is used wolffd@0: for the URL. Setting it to "_graphviz" will open a new window if it wolffd@0: doesn't already exist, or reuse it if it does. wolffd@0: If undefined, the value of the target is used. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Tooltip annotation attached to the tail of an edge. This is used only wolffd@0: if the edge has a tailURL attribute. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If the object has a URL, this attribute determines which window wolffd@0: of the browser is used for the URL. wolffd@0: See W3C documentation. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Tooltip annotation attached to the node or edge. If unset, Graphviz wolffd@0: will use the object's label if defined. wolffd@0: Note that if the label is a record specification or an HTML-like wolffd@0: label, the resulting tooltip may be unhelpful. In this case, if wolffd@0: tooltips will be generated, the user should set a tooltip wolffd@0: attribute explicitly. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If set explicitly to true or false, the value determines whether or not wolffd@0: internal bitmap rendering relies on a truecolor color model or uses wolffd@0: a color palette. wolffd@0: If the attribute is unset, truecolor is not used wolffd@0: unless there is a shapefile property wolffd@0: for some node in the graph. wolffd@0: The output model will use the input model when possible. wolffd@0: wolffd@0: wolffd@0: Use of color palettes results in less memory usage during creation of the wolffd@0: bitmaps and smaller output files. wolffd@0: wolffd@0: wolffd@0: Usually, the only time it is necessary to specify the truetype model wolffd@0: is if the graph uses more than 256 colors. wolffd@0: However, if one uses bgcolor=transparent with wolffd@0: a color palette, font wolffd@0: antialiasing can show up as a fuzzy white area around characters. wolffd@0: Using truecolor=true avoids this problem. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: If the input graph defines this attribute, the node is polygonal, wolffd@0: and output is dot or xdot, this attribute provides the wolffd@0: coordinates of the vertices of the node's polygon, in inches. wolffd@0: If the node is an ellipse or circle, the wolffd@0: samplepoints attribute affects wolffd@0: the output. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Clipping window on final drawing. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Factor to scale up drawing to allow margin for expansion in wolffd@0: Voronoi technique. dim' = (1+2*margin)*dim. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Weight of edge. In dot, the heavier the weight, the shorter, wolffd@0: straighter and more vertical the edge is. In neato, the heavier the wolffd@0: weight, the more neato will try to place the end points so that the wolffd@0: length of the edge is len. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Width of node, in inches. This is taken as the initial, minimum width wolffd@0: of the node. If fixedsize is true, this wolffd@0: will be the final width of the node. Otherwise, if the node label wolffd@0: requires more width to fit, the node's width will be increased to wolffd@0: contain the label. Note also that, if the output format is dot, the wolffd@0: value given to width will be the final value. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: Provides z coordinate value for 3D layouts and displays. If the wolffd@0: graph has dim set to 3 (or more), wolffd@0: neato will use a node's z value wolffd@0: for the z coordinate of its initial position if wolffd@0: its pos attribute is also defined. wolffd@0: wolffd@0: wolffd@0: Even if no z values are specified in the input, it is necessary to wolffd@0: declare a z attribute for nodes, e.g, using node[z=""] wolffd@0: in order to get z values on output. wolffd@0: Thus, setting dim=3 but not declaring z will wolffd@0: cause neato -Tvrml to wolffd@0: layout the graph in 3D but project the layout onto the xy-plane wolffd@0: for the rendering. If the z attribute is declared, the final rendering wolffd@0: will be in 3D. wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0: wolffd@0:
