Remarks:
 |
An ImageGear color space ID is actually a combination of values. It contains information about 1) color channels, 2) an alpha channel, and 3) extra channels. Examine the definition of enumIGColorSpaceIDs carefully (in accucnst.h) and use bitmasks such as IG_COLOR_SPACE_ID_ColorMask to isolate the information you want. |
