GLGETPOLYGONSTIPPLE() GLGETPOLYGONSTIPPLE() NAME glGetPolygonStipple - return the polygon stipple pattern C SPECIFICATION void glGetPolygonStipple( GLubyte *mask ) delim $$ PARAMETERS mask Returns the stipple pattern. The initial value is all 1's. DESCRIPTION glGetPolygonStipple returns to mask a $32 times 32$ polygon stipple pat- tern. The pattern is packed into memory as if glReadPixels with both height and width of 32, type of GL_BITMAP, and format of GL_COLOR_INDEX were called, and the stipple pattern were stored in an internal $32 times 32$ color index buffer. Unlike glReadPixels, however, pixel transfer oper- ations (shift, offset, pixel map) are not applied to the returned stipple image. NOTES If an error is generated, no change is made to the contents of mask. ERRORS GL_INVALID_OPERATION is generated if glGetPolygonStipple is executed be- tween the execution of glBegin and the corresponding execution of glEnd.
