- 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.
