- return the polygon stipple pattern



C SPECIFICATION


PARAMETERS

       _param1  Returns the stipple pattern. The initial value is
                all 1's.


DESCRIPTION

       glGetPolygonStipple returns to  _param1  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 trans-
       fer 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 con-
       tents of _param1.


ERRORS

       GL_INVALID_OPERATION is generated  if  glGetPolygonStipple
       is  executed between the execution of glBegin and the cor-
       responding execution of glEnd.
