c6fe6b0996 cleanup ArdourCanvas::WaveView
Mostly this just involved removing the private CacheEntry class that really served no further purpose once
the design reverted to a single cached image

2108525187 fix up size and drawing of measure lines, even when vertically scrolled 2013-06-24 23:03:11 -04:00
a1f858d3b2 an awful lot of tweaks to drawing details 2013-06-24 16:28:53 -04:00
27c943f1dd new image cache design for waveviews, with various fixes.
Rather than maintain a set of images in a cache, when we no longer have the required waveform data, create a new image that is appropriately centered and extends to roughly twice the screen width (or the limits of the region's source file(s), as necessary)

79384aeb66 initial semi-working attempt at getting waveview cache to work correctly 2013-06-18 23:03:20 -04:00
77f5f4c4bf basically operational switch to canvas drawing coordinates, although text and waves don't work, and redraw areas are too small 2013-06-18 08:23:06 -04:00

fee8de9787 Revert "cairo image crash debugging" and "initialize image data"
This reverts commit dfdb91b429
and commit 188d766757.

despite earlier assumptions the code is correct and there is
likely a memory corruption elsewhere.

9a3bc39970 tweak event/leave event delivery so that it applies to items being deleted as well as motion events (hmm, needed for item addition too ...) 2013-04-20 16:11:40 -04:00

ec102f94e1 various work waveview amplitude mgmt; fix playhead cursor drag from timebar click 2013-04-17 15:22:09 -04:00
8f2a2877b5 ArdourCanvas::Image allow to set custom data instead of class pre-allocated memory. 2013-04-17 20:26:09 +02:00
d1a05240ef fix clamping of line and rect coordinates to avoid issues with cairo when drawing way outside a surface's dimensions; move various coordinate methods down to Canvas, because they don't require GTK information; make visible_area() a Canvas virtual method so that we don't have to cast to call it 2013-04-17 10:53:17 -04:00
96eee9e7a1 change UIConfig to use accessor/setter methods like RCConfig so that ParameterChanged methods can actually be emitted; add variable (over a small range) background shading for all TimeAxisViewItems 2013-04-16 23:46:22 -04:00
381d4debf4 make waveform gradient depth continuously variable. color probably needs adjusting as do color stops to get a pleasing effect at most settings 2013-04-16 21:23:50 -04:00
c1df3295c1 virtual Fill:: and Outline:: methods so that Canvas::Items that cache image renderings of themselves can invalidate those caches when colors etc. change; add Item::{begin,end}_visual_change() so that we can notify the canvas more efficiently when *only* visual properties have changed and not the bounding box (probably needs to be used more widely) 2013-04-16 20:38:10 -04:00
81eed21dde some rationalization of how global WaveView properties and per-WaveView properties interact 2013-04-16 18:02:12 -04:00

37dd7e952b add headers to all canvas .cc and .h files 2013-04-15 22:10:18 -04:00
84fb0a8dce remove all XML related API from canvas. it may have been useful during development, but it is just a distraction - we will NEVER be saving or restoring canvas state via XML or any kind of serialized state 2013-04-15 21:57:08 -04:00
fe34485907 add new canvas Image item, with somewhat optimized API for asynchronous, threaded rendering directly into an image buffer suitable for use by cairo as a source surface (currently untested) 2013-04-15 21:40:15 -04:00
393ba98422 tweak time axis view item text positioning; allow ArdourCanvas::Text to have its width clamped, and use this as TAVI's get narrow so that text doesn't overflow 2013-04-15 14:45:22 -04:00
af4539f857 a few changes to fix region dragging, all related to coordinate system handling, which is now much simpler with the new canvas; more debugging output when asked for 2013-04-15 10:38:12 -04:00

053eaf77fd a variety of fixes for the cairocanvas, but it still buggy as hell handling events and lots of other stuff 2013-04-09 14:22:58 -04:00
