Examples of java.awt.image.ColorConvertOp.filter()

java.awt.image.ColorConvertOp.filter()
ColorConverts the source BufferedImage. If the destination image is null, a BufferedImage will be created with an appropriate ColorModel. @param src the source BufferedImage to be converted @param dest the destination BufferedImage, or null @return dest color converted from src or a new, converted BufferedImage if dest is null @exception IllegalArgumentException if dest is null and this op wasconstructed using the constructor which takes only a RenderingHints argument, since the operation is ill defined.

  public PlanarImage toDirectColorModel(RenderedImage img) {
    BufferedImage dest = new BufferedImage(img.getWidth(), img.getHeight(), BufferedImage.TYPE_4BYTE_ABGR);
    BufferedImage source = new BufferedImage(img.getColorModel(), (WritableRaster) img.getData(), img
        .getColorModel().isAlphaPremultiplied(), null);
    ColorConvertOp op = new ColorConvertOp(null);
    op.filter(source, dest);
