Examples of java.awt.image.ColorModel.createCompatibleSampleModel()

java.awt.image.ColorModel.createCompatibleSampleModel()
Creates a SampleModel with the specified width and height that has a data layout compatible with this ColorModel. Since ColorModel is an abstract class, any instance is an instance of a subclass. Subclasses must override this method since the implementation in this abstract class throws an UnsupportedOperationException. @param w the width to apply to the new SampleModel @param h the height to apply to the new SampleModel @return a SampleModel object with the specifiedwidth and height. @throws UnsupportedOperationException if thismethod is not supported by this ColorModel @see SampleModel

        if (tw > defSz) tw = defSz;
        int th = bounds.height;
        if (th > defSz) th = defSz;


        // fix my sample model so it makes sense given my size.
        SampleModel sm = cm.createCompatibleSampleModel(tw, th);


        // Finish initializing our base class...
        init((CachableRed)null, bounds, cm, sm, 0, 0, null);


        raster = Raster.createWritableRaster(sm, new Point(0, 0));
