Abstract
An application program may support multiple color spaces, such as Cyan Magenta Yellow blacK (CMYK) and Red Green Blue (RGB). Many computer operating systems have graphics drawing engines that only support RGB color space. For supporting non-RGB color spaces, the application program can use a color mapping table that defines a relationship between two color spaces such as CMYK and RGB. By generating unique RGB identifiers that can be passed through a graphics drawing engine and by using escape functions of a page description language, an application program can modify a printer file written in a page description language such that a non-RGB color space such as CMYK can be supported for publishing an electronic document.
