remove unused _wave_color member from waveview canvas item; use outline color for edge dots of waveforms instead of hardcoding black

drop use of bounding box to determine whether an item covers a point; add Item::covers(Duple const&)
...
Default implementation for Item still uses bounding box, but specializations for Arc (Circle), Polygon, Line and PolyLine have been added

changes to waveform clipping display
...
* clip level is now -0.9dbFS
* display of clipping is optional (see Theme Manager window)
* clipping is based on disk data, unscaled by region gain

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
2013-06-27 17:23:34 -04:00

(working) start of an experiment with pyramix-style waveform drawing

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)

get wave drawing improved, but commit before i tear it all up and go back to a single cached image per waveview

fix rect redraw problems caused by intersection requiring the usual 0.5 expansion (though consider a more general fix for this at teh group level)
2013-06-18 13:46:24 -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
f9a46e78d6
fix incorrect 3rd arg to AudioRegion::read_peaks() - was passing end, not cnt. Fixes waveforms at high zoom

don't invalidate image cache for every regionr esize, only region start changes

many pervasive changes primarily related to waveform drawing, particular content-dragging, colors, and more

no create cached waveview images that span from render-start to cache-start, but always clamp the end to render-end, to avoid creating over-sized images

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)

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
