|---|---|
AT_ERRCOUNT nErrcount; /* Number of errors on stack */ HIGDIBINFO hDIBInfo; /* DIB info handle */ HIGEAR hImage; /* HIGEAR handle of image */ AT_INT depth; /* Returned depth of first channel */ nErrcount = IG_image_DIB_info_get(hImage, &hDIBInfo); depth = IG_DIB_channel_depth_get(hDIBInfo, 0); |
