PS_SHADING(3)						     Library Functions Manual						     PS_SHADING(3)

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.

PS_SETCOLOR(3)								 1							    PS_SETCOLOR(3)

ps_setcolor - Sets current color

SYNOPSIS

       bool ps_setcolor (resource  $psdoc, string  $type, string  $colorspace, float  $c1, float  $c2, float  $c3, float  $c4)

DESCRIPTION

	Sets the color for drawing, filling, or both.

PARAMETERS

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

	      o $type
		- The parameter $type can be both, fill, or fillstroke.

	      o $colorspace
		-  The	colorspace  should  be one of gray, rgb, cmyk, spot, pattern. Depending on the colorspace either only the first, the first
		three or all parameters will be used.

	      o $c1
		- Depending on the colorspace this is either the red component (rgb), the cyan component (cmyk), the gray value (gray), the  iden-
		tifier of the spot color or the identifier of the pattern.

	      o $c2
		- Depending on the colorspace this is either the green component (rgb), the magenta component (cmyk).

	      o $c3
		- Depending on the colorspace this is either the blue component (rgb), the yellow component (cmyk).

	      o $c4
		- This must only be set in cmyk colorspace and specifies the black component.

BUGS

	The  second  parameter	is  currently  not always evaluated. The color is sometimes set for filling and drawing just as if fillstroke were
       passed.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.
