PS_begin_pattern — Starts a new pattern

#include <pslib.h>

int PS_begin_pattern(PSDoc *psdoc, float width, float height, float xstep, float ystep, int painttype)

A pattern can be thought of like a color for drawing and filling. Actually, PS_setcolor is used to apply a pattern. The pattern itself has given dimension an a stepping in horizontal and vertical direction. The stepping comes into effect when the area to be fill is larger than the pattern itself. In such a case the pattern will be repeated with a distance of xstep in horizontal and ystep in vertical direction.

Each call of PS_begin_pattern must be accompanied by a call to PS_end_pattern(3).

Returns identifier of the pattern or zero in case of an error. The identifier is a positiv number greater 0.
