Sets the color for drawing, filling, or both.

参数

psdoc

Resource identifier of the postscript file as returned by ps_new().

type

The parameter type can be both, fill, or fillstroke.

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.

c1

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

c2

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

c3

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

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.

成功时返回 true， 或者在失败时返回 false。
