Description copied from class: GraphicalObject

draw the object in the rectangular region rr, using scales sx and sy.

Overrides:

draw in class GraphicalObject

Following copied from interface: org.omegahat.Graphics.Primitives.GraphicalComponentInt

Parameters:

rr - the parents RectRegion in normalized device coordinates (NDC).

sx - the parent's horizontal scale for transforming between arbitrary units.

sy - the parent's vertical scale for transforming between arbitrary units.

origin - the parent's origin position.
