ccc9b6adee change rendering technique for waveforms, add back optional gradient, add back amplitude scaling, add rgb/hsv conversion utilities to canvas 2013-04-16 14:04:59 -04:00
a0044e5f71 add back various functionality to waveviews such as zero line, amplitude scaling 2013-04-16 10:07:52 -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
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
7e19053b88 Fix dragging objects on the canvas and remove redundant canvas groups
Delivery of fake motion events to the editor needed the event coordinates to be
in canvas space, as they are with "real" events. Editor and other objects had
many redundant groups from timbyr's work on gnomecanvas to scroll by moving
groups. We don't need this anymore with cairo-canvas (though possibly a
stationay background group for the canvas might be useful again one day as in
the SAE logo. Its implementation would be fairly different though, since we
would have to explicitly move the group on every scroll, since nothing else
ever moves on scroll).

Also tweaks to text item placement, and switch TimeAxisViewItem from
name_pixbuf to name_text, since ArdourCanvas::Text is already "pixbuf optimized".

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
4e84bc3a39 changes to get cairocanvas branch to build on OS X, with its stupid nil and Rect macros, plus some const_cast<> and unused variable fixes that should really be in master but will have to wait till we rebase master 2013-04-12 21:46:44 -04:00
e5a3747686 switch from frames_per_pixel to samples_per_pixel in the one canvas object that uses this 2013-04-12 11:31:17 -04:00
4258a34912 change all frame_to_pixel and pixel_to_frame to sample_to_pixel and pixel_to_sample 2013-04-12 11:15:45 -04:00

ee1f0520a8 many changes to get the cairo-canvas version much, much more functional. still problems with a lot of subtle and not-so-subtle issues 2013-04-11 20:19:22 -04:00
