ps_shading - Creates a shading for later use

SYNOPSIS

       int  ps_shading (resource  $psdoc, string  $type, float	$x0, float  $y0, float	$x1, float  $y1, float	$c1, float  $c2, float	$c3, float
       $c4, string  $optlist)

DESCRIPTION

	Creates a shading, which can be used by ps_shfill(3) or ps_shading_pattern(3).

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

PARAMETERS

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

	      o $type
		- 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).

	      o $x0, x1, y0, y1
		-  The	coordinates $x0, $y0, $x1, $y1 are the start and end point of the shading. If the type of shading is radial the two points
		are the middle points of a starting and ending circle.

	      o $c1, c2, c3, c4
		- See ps_setcolor(3) for their meaning.

	      o $optlist
		- If the shading is of type radial the $optlist must also contain the parameters r0 and r1 with the radius of the  start  and  end
		circle.

RETURN VALUES

	Returns the identifier of the pattern or FALSE on failure.

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.
