Mon, 12 Nov 2018 11:34:34 +0000 Chris Cannam Use log-frequency rather than log-bin for calculating x coord in spectrum. This has the advantage that frequency positions don't move when we change the window size or oversampling ratio, but it does give us an unhelpfully large amount of space for very low frequencies - to be considered spectrogramparam
Wed, 07 Nov 2018 15:59:10 +0000 Chris Cannam Switch spectrum to antialiased drawing with considerable speedup for the dense areas; take horizontal scale height into account when rendering slice layer height spectrogramparam
Wed, 07 Nov 2018 11:37:51 +0000 Chris Cannam Add oversampling option to spectrum as well spectrogramparam
Thu, 18 Oct 2018 13:21:56 +0100 Chris Cannam Add mechanism for saving/loading colour maps by name/id rather than by numerical index, for future compatibility when adding to or changing the supported colour maps. Add two new colour maps (and one old one). Write out backward-compatible numerical indices for use when reloading in older versions. Also add a mechanism to invert the colour map, though I don't think it turns out useful enough to include in the UI.
Thu, 03 May 2018 15:15:15 +0100 Chris Cannam Provide linear horizontal scale in spectrum as well as log; fix bin positioning and colour scale property box updating; ensure proper background colour and visibility of peak lines horizontal-scale
Tue, 01 May 2018 16:14:22 +0100 Chris Cannam Branch toward adding horizontal numerical scales to things horizontal-scale
Thu, 01 Mar 2018 18:02:22 +0000 Chris Cannam Untabify
Wed, 22 Feb 2017 11:19:51 +0000 Chris Cannam Overrides
Tue, 07 Feb 2017 14:55:19 +0000 Chris Cannam Some work to make spectrum layers (and slice layers generally) zoomable in the frequency axis. Also fixes a number of view id mixups in SliceLayer which broke offset calculations for the x axis scale.
Thu, 26 Jan 2017 21:17:59 +0000 Chris Cannam Fix silly definition that prevented spectrum scale from appearing
Tue, 17 Mar 2015 16:56:03 +0000 Chris Cannam Many fixes for the previous stuff osx-retina
Tue, 17 Mar 2015 15:05:25 +0000 Chris Cannam Start trying to introduce LayerGeometryProvider as proxyable interface for View methods that the Layer wants to use osx-retina
Mon, 09 Mar 2015 14:35:21 +0000 Chris Cannam Working through the float/double and int/sv_frame_t fixes cxx11
Tue, 17 Jun 2014 15:18:06 +0100 Chris Cannam Remove size_t's and fix warnings in layer/ warnfix_no_size_t
Mon, 30 Jan 2012 16:01:59 +0000 Chris Cannam Give a dedicated key to toggling the centre line, and move it out of the overlay level setting -- reducing number of overlay levels to 3. Introduce two distinct vertical scale types (so that we can hide the spectrogram colour scale part easily)
