glGetPolygonStipple.3gl

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.
