NAME
fglGetPolygonStipple - return the polygon stipple pattern
FORTRAN SPECIFICATION
SUBROUTINE fglGetPolygonStipple( CHARACTER*256 mask )
PARAMETERS
mask Returns the stipple pattern. The initial value is all
1's.
DESCRIPTION
fglGetPolygonStipple returns to mask a 32x32 polygon stipple
pattern. The pattern is packed into memory as if
fglReadPixels 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 fglReadPixels, 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 fglGetPolygonStipple is
executed between the execution of fglBegin and the
corresponding execution of fglEnd.
