SYNOPSIS
#include <pslib.h>
void PS_shfill(PSDoc *psdoc, int shading)
DESCRIPTION
Draws the shading whose id is passed in parameter
shading. The name of the function is somewhat
misleading. It does not fill an area like PS_fill(3) but simply draws the shading without any bounding box. If you want to
restrict the schading to a certain area, then you will have to
call PS_clip(3) before.
Using PS_shfill(3) is often easier than creating a shading pattern with PS_shading_pattern(3)and using it for filling.
