fglGetPolygonStipple(3G)

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 32 x 32 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 32 x 32 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.
