Copy Code
AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGEAR hImage;          /* Handle of image */
enumIGColorSpaceIDs cs; /* Color space ID */
AT_BOOL bIndexed;       /* Is the image indexed? */
nErrcount = IG_image_colorspace_get(hImage, &cs);
if ((cs & IG_COLOR_SPACE_ID_ColorMask) == IG_COLOR_SPACE_ID_I)
    bIndexed = TRUE;
    bIndexed = FALSE;


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.
