This function maps from legacy ImageGear color space ID (enumColorSpaces) to current ImageGear color space ID (enumIGColorSpaceIDs).

        enumColorSpaces colorSpace
);

Example:

 
Copy Code
enumColorSpaces oldCS;  /* Old color space ID */
enumIGColorSpaceIDs cs; /* New color space ID */
oldCS = IG_COLOR_SPACE_CMYK;
cs = IG_util_colorspace_value_to_ids(oldCS);
/* cs is now IG_COLOR_SPACE_ID_CMYK */
oldCS = IG_COLOR_SPACE_RGBA;
cs = IG_util_colorspace_value_to_ids(oldCS);
/* cs is now IG_COLOR_SPACE_ID_RGBA */

Remarks:

This function exists because the newer color space IDs are different and can store more information. See accucnst.h for the definitions of these enumerations.
