PS_SETCOLOR(3)						     Library Functions Manual						    PS_SETCOLOR(3)

NAME

       PS_setcolor -- Sets current color

SYNOPSIS

       #include <pslib.h>

       void PS_setcolor(PSDoc *psdoc, const char *type, const char *colorspace, float c1, float c2, float c3, float c4)

DESCRIPTION

       Sets  the color for drawing, filling, or both. The colorspace should be one of 'gray', 'spot', 'rgb, 'cmyk', or 'pattern'. Depending on the
       colorspace either only the first, the first two, the first three all or remaining parameters will be used. If colorspace is 'pattern'  then
       c1  must  contain  the pattern id as returned by PS_begin_pattern(3). If colorspace is 'spot' then the c1 must contain the spot color id as
       returned by PS_makespotcolor(3) and the c2 must contain the tint value for the color.

       The parameter type can be 'fillstroke', 'fill', or 'stroke'.

BUGS

       The second parameter is currently not in any case evaluated.  The color is always set for filling and  drawing  just  as  if  'both'  where
       passed.	 If  you want to set the color to define a spot color from it, you will have to pass 'both' or 'fill', because PS_makespotcolor(3)
       utilizes the current fill color.

ps_begin_pattern - Start a new pattern

SYNOPSIS

       int ps_begin_pattern (resource  $psdoc, float  $width, float  $height, float  $xstep, float  $ystep, int  $painttype)

DESCRIPTION

	Starts	a  new pattern. A pattern is like a page containing e.g. a drawing which can be used for filling areas. It is used like a color by
       calling ps_setcolor(3) and setting the color space to pattern.

PARAMETERS

	      o $psdoc
		- Resource identifier of the postscript file as returned by ps_new(3).

	      o $width
		- The width of the pattern in pixel.

	      o $height
		- The height of the pattern in pixel.

	      o $x-step
		- The distance in pixel of placements of the pattern in horizontal direction.

	      o $y-step
		- The distance in pixel of placements of the pattern in vertical direction.

	      o $painttype
		- Must be 1 or 2.

RETURN VALUES

	The identifier of the pattern or FALSE on failure.
