glGetPolygonStipple(3G)	       OpenGL Reference	       glGetPolygonStipple(3G)



NAME
     glGetPolygonStipple - return the polygon stipple pattern


C SPECIFICATION
     void glGetPolygonStipple( GLubyte *mask )


PARAMETERS
     mask  Returns the stipple pattern.

DESCRIPTION
     glGetPolygonStipple returns to mask a 32x32 polygon stipple 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	32x32 color index
     buffer.  Unlike glReadPixels, however, pixel transfer operations (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
     between the execution of glBegin and the corresponding execution of
     glEnd.
