To write the image to a GIF it has to be either a grayscale image or an RGB image with color expressed via a colormap, i.e., it must have an IndexColorModel. If you have a 3-band RGB image, you can convert it to a colormap image using the JAI ErrorDiffusion or OrderedDither operations. The LUT required for ErrorDiffusion may be generated using the ColorQuantizer operation. Or you can use the ColorQuantizer operation's image output which determines the color index using nearest color.
