Name | Meaning |
---|---|
|
The function was called between a call to glBegin and the corresponding call to glEnd. |
The glGetPolygonStipple function returns a 32x32 polygon stipple pattern through the mask parameter. 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, and pixel map) are not applied to the returned stipple image.
If an error is generated, no change is made to the contents of mask.
