use of java.awt.image.ColorModel in project jdk8u_jdk by JetBrains.

the class PngDitDepthTest method main.

public static void main(String[] args) throws IIOInvalidTreeException {
    // getting the writer for the png format

Example 15 with ColorModel

use of java.awt.image.ColorModel in project jdk8u_jdk by JetBrains.

the class GraphicsConfiguration method createCompatibleImage.

/**
     * Returns a {@link BufferedImage} with a data layout and color model

     * method has nothing to do with memory-mapping
     * a device.  The returned <code>BufferedImage</code> has
     * a layout and color model that is closest to this native device
     * configuration and can therefore be optimally blitted to this
     * device.

     * @param height the height of the returned <code>BufferedImage</code>
     * @return a <code>BufferedImage</code> whose data layout and color
     * model is compatible with this <code>GraphicsConfiguration</code>.
