Returns a data element array representation of a pixel in this ColorModel , given an array of normalized color/alpha components.

Usage

From source file:ComponentTest.java

public static void main(String[] args) {
    ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_sRGB);
    ColorModel cm = new ComponentColorModel(cs, new int[] { 5, 6, 5 }, false, false, Transparency.OPAQUE,
            DataBuffer.TYPE_BYTE);

    Color fifty = new Color(cs, new float[] { 1.0f, 1.0f, 1.0f }, 0);
    float[] components = fifty.getComponents(null);
    System.out.print("Original normalized components: ");
    for (int i = 0; i < 3; i++)
        System.out.print(components[i] + " ");
    System.out.println();//  www  . j a va2s .c  o m
    int[] unnormalized = cm.getUnnormalizedComponents(components, 0, null, 0);
    System.out.print("Original unnormalized components: ");
    for (int i = 0; i < 3; i++)
        System.out.print(unnormalized[i] + " ");
    System.out.println();
    Object pixel = cm.getDataElements(unnormalized, 0, (Object) null);
    System.out.print("Pixel samples: ");
    byte[] pixelBytes = (byte[]) pixel;
    for (int i = 0; i < 3; i++)
        System.out.print(pixelBytes[i] + " ");
    System.out.println();

    unnormalized = cm.getComponents(pixel, null, 0);
    System.out.print("Derived unnormalized components: ");
