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 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.
