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. The initial value is all 1's.

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 GLBITMAP, and format of GLCOLORINDEX 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
     GLINVALIDOPERATION is generated if glGetPolygonStipple is executed
     between the execution of glBegin and the corresponding execution of
     glEnd.
