Paths
Approximate a circular arc by one cubic bezier curve. larger arc angles mean larger distortions
addBezierCubic :: Point -> Point -> Point -> Draw ()Source
Append a cubic Bezier curve to the current path. The curve extends from the current point to the point (x3 , y3), using (x1 , y1 ) and (x2, y2) as the Bezier control points
addPolygonToPath :: [Point] -> Draw ()Source
Add a polygon to current path
addLineToPath :: Point -> Draw ()Source
strokePath :: Draw ()Source
Draw current path
fillAndStrokePath :: Draw ()Source
Fill current path
fillPathEO :: Draw ()Source
Fill current path using even odd rule
fillAndStrokePathEO :: Draw ()Source
Fill current path using even odd rule
setAsClipPath :: Draw ()Source
Set clipping path
setAsClipPathEO :: Draw ()Source
Set clipping path
