erase-circle-sector

Arguments: stream center radius start-angle length-angle

Erases from stream (i.e. replaces with the background color or texture) the specified circle-sector. A circle-sector is an arc with length length-angle starting at start-angle on the circle defined by radius and center, along with the radii connecting the vertices of the arc with the center (i.e. a shape like a piece of pie).

center must be a position object, as created with make-position. stream should be a cg-stream.

Contrast with draw-circle-sector which draws the circle-sector on stream.
