Detailed Description

DKArrowStroke is a rasterizer that implements arrowheads on the ends of paths.

DKArrowStroke is a rasterizer that implements arrowheads on the ends of paths. The heads are drawn by filling the arrowhead using the same colour as the stroke, thus seamlessly blending the head into the path. Where multiple strokes are used, the resulting effect should be correct when angles are kept the same and lengths are calculated from the stroke width.
