Interpolation hint value -- the color sample of the nearest neighboring integer coordinate sample in the image is used.

Usage

From source file:lucee.runtime.img.Image.java

public void resizeImage(int width, int height, int interpolation) throws ExpressionException {
    Object ip;//from w w w  .j ava 2 s  .co  m
    if (interpolation == IPC_NEAREST)
        ip = RenderingHints.VALUE_INTERPOLATION_NEAREST_NEIGHBOR;
    else if (interpolation == IPC_BICUBIC)
        ip = RenderingHints.VALUE_INTERPOLATION_BICUBIC;
    else if (interpolation == IPC_BILINEAR)
        ip = RenderingHints.VALUE_INTERPOLATION_BILINEAR;
    else
        throw new ExpressionException("invalid interpoltion definition");

    BufferedImage dst = new BufferedImage(width, height, image().getType());
    Graphics2D graphics = dst.createGraphics();
    graphics.setRenderingHint(RenderingHints.KEY_INTERPOLATION, ip);
    graphics.drawImage(image(), 0, 0, width, height, null);
    graphics.dispose();
