GLGETPOLYGONSTIPPLE(3UNIX Programmer's ManGLGETPOLYGONSTIPPLE(3G)
glGetPolygonStipple - return the polygon stipple pattern
void glGetPolygonStipple( GLubyte *mask )
mask Returns the stipple pattern. The initial value is all
1's.
glGetPolygonStipple returns to mask a 32 x 32 polygon stip-
ple pattern. 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 x 32 color
index buffer. Unlike glReadPixels, however, pixel transfer
operations (shift, offset, pixel map) are not applied to the
returned stipple image.
If an error is generated, no change is made to the contents
of mask.
GL_INVALID_OPERATION is generated if glGetPolygonStipple is
executed between the execution of glBegin and the
corresponding execution of glEnd.
