Remarks:

While support for IG_IP_color_combine() is being maintained, it is recommended that you use this newer function. The additional benefit of this function is that it allows you to choose a color space for the destination image. For example, you can choose to store your destination image using the CMYK color scheme. Currently, the dst_color_space parameter can take one of the following constants as its setting: IG_COLOR_SPACE_RGBand IG_COLOR_SPACE_CMYK. In order to set it to CMYK, you must be sure that you first call IG_color_space_level_set() function with settings of IG_COLOR_SPACE_CMYK and IG_FULL_SUPPORT.
