590882f3c8 change Canvas heirarchy and constructors
Items no longer need a parent group (they require a Canvas pointer instead), so all constructors have been rationalized
and have two variants, one with a parent and one with a canvas.

All Items now inherit from Fill and Outline, to banish diagonal inheritance and virtual base classes and all that.

There were zero changes to the Ardour GUI arising from these changes.

0ce393f051 likely fix for Canvas::Image positioning under new coordinate/render rules 2013-06-22 14:59:43 -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.

8f2a2877b5 ArdourCanvas::Image allow to set custom data instead of class pre-allocated memory. 2013-04-17 20:26:09 +02:00
ef60401d92 (hopefully) fix double-buffering design of ArdourCanvas::Image 2013-04-16 14:20:04 -04:00
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
37dd7e952b add headers to all canvas .cc and .h files 2013-04-15 22:10:18 -04:00
64d3763652 remove all xml++.h inclusion by canvas implementations 2013-04-15 22:00:13 -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
