GLGETPOLYGONSTIPPLE(3G)GLGETPOLYGONSTIPPLE(3G)NAMEglGetPolygonStipple - 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.
DESCRIPTIONglGetPolygonStipple returns to mask a $32 ~times~ 32$ 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 $32 ~times~ 32$ 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.
