NAME    [Toc]    [Back]

       glGetPolygonStipple - return the polygon stipple pattern

SYNOPSIS    [Toc]    [Back]

       void glGetPolygonStipple(
               GLubyte *mask );

PARAMETERS    [Toc]    [Back]

       Returns the stipple pattern. The initial value is all 1's.

DESCRIPTION    [Toc]    [Back]

       glGetPolygonStipple() 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    [Toc]    [Back]

       If  an  error  is generated, no change is made to the contents
 of mask.

ERRORS    [Toc]    [Back]

       GL_INVALID_OPERATION is generated if glGetPolygonStipple()
       is  executed  between  the  execution of glBegin() and the
       corresponding execution of glEnd().
