6 glGetPolygonStipple - return the polygon stipple pattern

9 void glGetPolygonStipple(GLubyte * pattern);
10
12 pattern
13 Returns the stipple pattern. The initial value is all 1's.
14
16 glGetPolygonStipple returns to pattern a 32 × 32 polygon stipple
17 pattern. The pattern is packed into memory as if glReadPixels() with
18 both height and width of 32, type of GL_BITMAP, and format of
19 GL_COLOR_INDEX were called, and the stipple pattern were stored in an
20 internal 32 × 32 color index buffer. Unlike glReadPixels(), however,
21 pixel transfer operations (shift, offset, pixel map) are not applied to
22 the returned stipple image.
23
24 If a non-zero named buffer object is bound to the GL_PIXEL_PACK_BUFFER
25 target (see glBindBuffer()) while a polygon stipple pattern is
26 requested, pattern is treated as a byte offset into the buffer object's
27 data store.
28
30 If an error is generated, no change is made to the contents of pattern.
31
33 GL_INVALID_OPERATION is generated if a non-zero buffer object name is
34 bound to the GL_PIXEL_PACK_BUFFER target and the buffer object's data
35 store is currently mapped.
36
37 GL_INVALID_OPERATION is generated if a non-zero buffer object name is
38 bound to the GL_PIXEL_PACK_BUFFER target and the data would be packed
39 to the buffer object such that the memory writes required would exceed
40 the data store size.
41
42 GL_INVALID_OPERATION is generated if glGetPolygonStipple is executed
43 between the execution of glBegin() and the corresponding execution of
44 glEnd().
