Class ReduceRGB
java.lang.Object

net.sourceforge.jiu.color.reduction.ReduceRGB
public class ReduceRGB
- extends ImageToImageOperation
Reduces the color depth of RGB truecolor images.
This class uses a simple approach, it just drops some of the
lowest bits and scales the value back to eight or sixteen bits per sample.
Supported image classes
This class works with RGB24Image
and RGB48Image
.
Usage example
Reduce a 24 or 48 bits per pixel RGB image to 15 bits per pixel:
PixelImage inputImage = ...; // initialize
ReduceRGB reduce = new ReduceRGB();
reduce.setBitsPerSample(5);
reduce.setInputImage(inputImage);
reduce.process();
PixelImage reducedImage = reduce.getOutputImage();
