From 206d0e598adb66e2b23a39a7d11e2f5087513205 Mon Sep 17 00:00:00 2001 From: warriorofwire <3454741+WarriorOfWire@users.noreply.github.com> Date: Sat, 2 May 2020 02:21:35 -0700 Subject: Add vectorio: for drawing shapes vectorio builds on m4 express feather Concrete shapes are composed into a VectorShape which is put into a displayio Group for display. VectorShape provides transpose and x/y positioning for shape implementations. Included Shapes: * Circle - A radius; Circle is positioned at its axis in the VectorShape. - You can freely modify the radius to grow and shrink the circle in-place. * Polygon - An ordered list of points. - Beteween each successive point an edge is inferred. A final edge closing the shape is inferred between the last point and the first point. - You can modify the points in a Polygon. The points' coordinate system is relative to (0, 0) so if you'd like a top-center justified 10x20 rectangle you can do points [(-5, 0), (5, 0), (5, 20), (0, 20)] and your VectorShape x and y properties will position the rectangle relative to its top center point * Rectangle A width and a height. --- shared-module/displayio/display_core.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'shared-module/displayio/display_core.c') diff --git a/shared-module/displayio/display_core.c b/shared-module/displayio/display_core.c index d01100f7f..43f2d1937 100644 --- a/shared-module/displayio/display_core.c +++ b/shared-module/displayio/display_core.c @@ -40,6 +40,9 @@ #include #include +#define DISPLAYIO_CORE_DEBUG(...)
