/* Use the color space converter to convert an image to 8-bit indexed, no alpha or extra channels */ AT_ERRCOUNT nErrcount; /* Number of errors on stack */ HIGCSCONVERTER hCSConv; /* Color space converter handle */ HIGEAR hImage; /* HIGEAR handle of image */ AT_INT depths[] = {8}; /* Result channel depths */ AT_RGBQUAD pal[256]; /* Result palette */ AT_INT nEntries; /* # of palette entries */ nErrcount = IG_colorspace_conversion_create_from_image( hImage, IG_COLOR_SPACE_ID_I, depths, 1, NULL, &hCSConv); nErrcount = IG_colorspace_conversion_apply_to_image( hCSConv, hImage); nErrcount = IG_colorspace_conversion_result_palette_get( hCSConv, pal, &nEntries); nErrcount = IG_colorspace_conversion_destroy(hCSConv); |

Remarks:
If the resultant color space is indexed, paletteLength will be filled with the quantity of palette entries.
