%EXPORTFIG  Export a figure.
%   EXPORTFIG(H, FILENAME) writes the figure H to FILENAME.  H is
%   a figure handle and FILENAME is a string that specifies the
%   name of the output file.
%
%   EXPORTFIG(H, FILENAME, OPTIONS) writes the figure H to FILENAME
%   with options initially specified by the structure OPTIONS. The
%   field names of OPTIONS must be legal parameters listed below
%   and the field values must be legal values for the corresponding
%   parameter. Default options can be set in releases prior to R12
%   by storing the OPTIONS structure in the root object's appdata
%   with the command 
%      setappdata(0,'exportfigdefaults', OPTIONS) 
%   and for releases after R12 by setting the preference with the
%   command 
%      setpref('exportfig', 'defaults', OPTIONS) 
%
%   EXPORTFIG(...,PARAM1,VAL1,PARAM2,VAL2,...) specifies
%   parameters that control various characteristics of the output
%   file. Any parameter value can be the string 'auto' which means
%   the parameter uses the default factory behavior, overriding
%   any other default for the parameter.
%
%   Format Paramter:
%     'Format'  a string
%          specifies the output format. Defaults to 'eps'. For a
%          list of export formats type 'help print'.
%     'Preview' one of the strings 'none', 'tiff'
%          specifies a preview for EPS files. Defaults to 'none'.
%
%   Size Parameters:
%     'Width'   a positive scalar
%          specifies the width in the figure's PaperUnits
%     'Height'  a positive scalar
%          specifies the height in the figure's PaperUnits
%     'Bounds' one of the strings 'tight', 'loose'
%          specifies a tight or loose bounding box. Defaults to 'tight'.
%     'Reference' an axes handle or a string
%          specifies that the width and height parameters
%          are relative to the given axes. If a string is
%          specified then it must evaluate to an axes handle.
%
%     Specifying only one dimension sets the other dimension
%     so that the exported aspect ratio is the same as the
%     figure's or reference axes' current aspect ratio. 
%     If neither dimension is specified the size defaults to 
%     the width and height from the figure's or reference
%     axes' size. Tight bounding boxes are only computed for
%     2-D views and in that case the computed bounds enclose all
%     text objects.
%           
%   Rendering Parameters:
%     'Color'     one of the strings 'bw', 'gray', 'cmyk'
%         'bw'    specifies that lines and text are exported in
%                 black and all other objects in grayscale
%         'gray'  specifies that all objects are exported in grayscale
%         'rgb'   specifies that all objects are exported in color
%                 using the RGB color space
%         'cmyk'  specifies that all objects are exported in color
%                 using the CMYK color space
%     'Renderer'  one of 'painters', 'zbuffer', 'opengl'
%         specifies the renderer to use
%     'Resolution'   a positive scalar
%         specifies the resolution in dots-per-inch.
%     'LockAxes'  one of 0 or 1
%         specifies that all axes limits and ticks should be fixed
%         while exporting.
%     
%     The default color setting is 'bw'.
%
%   Font Parameters:
%     'FontMode'     one of the strings 'scaled', 'fixed'
%     'FontSize'     a positive scalar
%          in 'scaled' mode multiplies with the font size of each
%          text object to obtain the exported font size
%          in 'fixed' mode specifies the font size of all text
%          objects in points
%     'DefaultFixedFontSize' a positive scalar
%          in 'fixed' mode specified the default font size in
%          points
%     'FontSizeMin' a positive scalar
%          specifies the minimum font size allowed after scaling
%     'FontSizeMax' a positive scalar
%          specifies the maximum font size allowed after scaling
%     'FontEncoding' one of the strings 'latin1', 'adobe'
%          specifies the character encoding of the font
%     'SeparateText' one of 0 or 1
%          specifies that the text objects are stored in separate
%          file as EPS with the base filename having '_t' appended.
%
%     If FontMode is 'scaled' but FontSize is not specified then a
%     scaling factor is computed from the ratio of the size of the
%     exported figure to the size of the actual figure.
%
%     The default 'FontMode' setting is 'scaled'.
%
%   Line Width Parameters:
%     'LineMode'     one of the strings 'scaled', 'fixed'
%     'LineWidth'    a positive scalar
%     'DefaultFixedLineWidth' a positive scalar
%     'LineWidthMin' a positive scalar
%          specifies the minimum line width allowed after scaling
%     'LineWidthMax' a positive scalar
%          specifies the maximum line width allowed after scaling
%     The semantics of 'Line' parameters are exactly the
%     same as the corresponding 'Font' parameters, except that
%     they apply to line widths instead of font sizes.
%
%   Style Map Parameter:
%     'LineStyleMap'    one of [], 'bw', or a function name or handle
%          specifies how to map line colors to styles. An empty
%          style map means styles are not changed. The style map
%          'bw' is a built-in mapping that maps lines with the same
%          color to the same style and otherwise cycles through the
%          available styles. A user-specified map is a function
%          that takes as input a cell array of line objects and
%          outputs a cell array of line style strings. The default
%          map is [].
%      
%   Examples:
%     exportfig(gcf,'fig1.eps','height',3);
%       Exports the current figure to the file named 'fig1.eps' with
%       a height of 3 inches (assuming the figure's PaperUnits is 
%       inches) and an aspect ratio the same as the figure's aspect
%       ratio on screen.
%
%     opts = struct('FontMode','fixed','FontSize',10,'height',3);
%     exportfig(gcf, 'fig2.eps', opts, 'height', 5);
%       Exports the current figure to 'fig2.eps' with all
%       text in 10 point fonts and with height 5 inches.
