Examples of railo.runtime.img.filter.QuantizeFilter

railo.runtime.img.filter.QuantizeFilter
A filter which quantizes an image to a set number of colors - useful for producing images which are to be encoded using an index color model. The filter can perform Floyd-Steinberg error-diffusion dithering if required. At present, the quantization is done using an octtree algorithm but I eventually hope to add more quantization methods such as median cut. Note: at present, the filter produces an image which uses the RGB color model (because the application it was written for required it). I hope to extend it to produce an IndexColorModel by request.

    filter.setDither(true);
    //filter.setNumColors(8);
    filter.filter(src, dst);
    


    //image(Quantizer.quantize(image(), 8));

      GifEncoder enc = new GifEncoder(dst);
