Remove unused function
...
Cairo::curve_to renders cubic Bézier splines, those are not
generally useful in a DAW context.
Canvas::Curve implements centripetal catmull-rom spline drawing
which can be used for fades and automation interpolation.

Update canvas/UI lib GPL boilerplate and (C) from git log

remove use of boost::optional to define "undefined" Canvas::Rect, and use Rect::empty instead.
...
This commit includes Rect::operator bool() which might be a candidate for removal in a future commit, in an attempt
to make the meaning clearer

NOOP, remove trailing tabs/whitespace.

globally remove all trailing whitespace from ardour code base.
...
Paul Davis was responsible for introducing almost all of this.

slightly increase size of a Canvas::PolyItem, to avoid left-over pixels when dragging (as well as other general incorrectness

refactor Canvas so that all Items have children; add Container abstract base class; rename Group as "Layout" and retain only drawing semantics

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.

don't queue redraws when various canvas item properties are "reset" to the same value, plus supporting functions

pixel-align canvas PolyItems with single-pixel outlines, for crispness

make PolyLine use distance_to_segment_squared(), and add separate (null, for now) method Curve::covers(Duple) because the math there needs to be different, maybe
2013-12-09 17:24:34 -05:00
6473cc7cb4
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

basically operational switch to canvas drawing coordinates, although text and waves don't work, and redraw areas are too small

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

add (bezier) curves to canvas, use for automation lines; fix issue with rectangles missing their upper line segment; more cairo canvas fixes
