public DrawShape(ShapeKind kind, PixelRect bounds, TPixel pixel, OpacityLock opacity = OpacityLock.Locked);

Draws a filled shape.

Parameters

kind (ShapeKind) - Which shape.
bounds (PixelRect) - Its bounding box.
pixel (TPixel) - The pixel to write.
opacity (OpacityLock) - Whether partial alpha is admitted; locked by default.

protected override IReadOnlyList<(int, int, TPixel)> ComputePixels(IEditSurface<TPixel> surface);

Target pixels and their new values. Only in-bounds pixels, each coordinate at most once; computed before any mutation.

Parameters

surface (IEditSurface<TPixel>) - The surface being edited, for reading the pixels the edit depends on.

Returns. The pixels to write, before the opacity lock is applied to them.
