624a86c39d lots more color work, closer and closer to being ready for ... being taken apart again 2014-12-08 22:02:38 -05:00
9ac7ddb31d remove all explicit button text colors; use contrasting_text_color() instead.
Also, use a slightly off-white rather than pure white, which should really be configurable

9266e7524a experimental drawing optimization.
Q: is bounding_box(); etc more complex than queuing draw?

either way, canvas should eventually switch to
use an optimized OptimizingLookupTable.

b2b736d596 tweaks for the monitor section. refactoring of some buttons, using new ArdourKnob instead of VolumeController. New ArdourDisplay shows a controllables user value, and provides support for preset values (hardcoded at present). Further refactoring to come, so that ArdourWidgets are derived from a common class. Controllable now has more responsibility for scaling between internal, user, and interface (knob percent) values. This also needs more refactoring and might have some unintended consequences. tested with audio and nothing seems amiss, yet. 2014-07-18 08:47:45 -05:00

437099fff9 completely rethink waveform rendering (again)
There are 3 possible components to draw at each x-axis position: the waveform "line", the zero line and an outline/clip indicator.
We have to decide which of the 3 to draw at each position, pixel by pixel. This makes the rendering less efficient but it is
the only way I can see to do this correctly.

Items no longer need a parent group (they require a Canvas pointer instead), so all constructors have been rationalized

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.

7a05dde39d Use a dumb cache for waveview ImageSurfaces. This halves the size of the
previous one, but usually ends up using three of them at the current
CACHE_HIGH_WATER setting.
Should result in a smaller memory footprint for sessions with
multiple copies of nearby audio segments (electronic style).
The downside is the larger memory footprint for linear recording
sessions if CACHE_HIGH_WATER > 1 (1 giving a max of two
half - sized cache entries per audio stream).

6019f06bdf different approach to independent scrolling, involving ArdourCanvas::ScrollGroup
The idea now is that a scroll group item can be added to the canvas which will causes its children to scroll in either or both
directions (horizontal or vertical). There are few complications: the position() of the ScrollGroup is ambiguous depending
on whether you want it with scroll taken into account or not, so Item::canvas_position() was added, which defaults to
the same value as Item::position() but is overridden by ScrollGroup to return the position independent of scrolling. This
method is used when translating between item/canvas/window coordinate systems.

Note that the basic idea is that we MOVE the scroll group when a scroll happens. This mirrors what happens in the GnomeCanvas,
where Nick Mainsbridge came up with a great idea that allowed unification of the time bar and track canvases.

a08c0ea1da manually revert change to canvas expose handling in fee026c5ef
Breaking out the rectangles implies a z-axis ordering of drawing,because the rect drawn last will implicitly be "on top".
But redraw areas are not submitted with any z-axis information, and so drawing like this breaks canvas layering. It
would be more efficient to draw the rects separately, but we don't have any ordering information and so we cannot do it
correctly.
