Paul Davis	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
Robin Gareus	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.	2013-04-20 23:36:13 +02:00
Robin Gareus	188d766757	initialize image data.	2013-04-20 22:07:43 +02:00
Robin Gareus	8f2a2877b5	ArdourCanvas::Image allow to set custom data instead of class pre-allocated memory.	2013-04-17 20:26:09 +02:00
Paul Davis	ef60401d92	(hopefully) fix double-buffering design of ArdourCanvas::Image	2013-04-16 14:20:04 -04:00
Paul Davis	be23e48e7f	add some comments to Canvas::Image and ensure that the canvas redraws after a put_image() call is handled in the GUI thread	2013-04-15 22:34:36 -04:00
Paul Davis	37dd7e952b	add headers to all canvas .cc and .h files	2013-04-15 22:10:18 -04:00
Paul Davis	64d3763652	remove all xml++.h inclusion by canvas implementations	2013-04-15 22:00:13 -04:00
Paul Davis	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
Paul Davis	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
