NAME

       PS_shading — Create shading

SYNOPSIS

       #include <pslib.h>

       int  PS_shading(PSDoc  *psdoc, const char *shtype, float x0, float y0, float x1, float y1,
       float c1, float c2, float c3, float c4, const char *optlist)

DESCRIPTION

       This   function   creates   a   shading   which   can   be   used   by   PS_shfill(3)   or
       PS_shading_pattern(3). The type of shading can be either `radial' or `axial'. Each shading
       starts with the current fill color and ends with the given  color  values  passed  in  the
       parameters  c1  to  c4 (see PS_setcolor(3)         for their meaning). The coordinates x0,
       y0, x1, y1 are the start and end point of the shading.  If the shading is of type `radial'
       the  option  list  must also contain the parameters r0 and r1 with the radius of the start
       and end circle.

       The color of the shading can be in any color space except for `pattern'.

RETURN VALUE

       Returns the identifier of the shading or zero in case of an error.  The  identifier  is  a
       positiv number.
