Example 11 with ColorConvertOp

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

the class AlphaTest method main.

public static void main(String[] args) {
    ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
    ColorConvertOp op = new ColorConvertOp(cs, null);
    // create source image filled with an opaque color
    BufferedImage src = createSrc();
    int srcAlpha = getAlpha(src);
    System.out.printf("Src alpha: 0x%02x\n", srcAlpha);
    // create clear (transparent black) destination image
    BufferedImage dst = createDst();
    int dstAlpha = getAlpha(dst);
    System.out.printf("Dst alpha: 0x%02x\n", dstAlpha);
    dst = op.filter(src, dst);
    dstAlpha = getAlpha(dst);
    // we expect that destination image is opaque
    // i.e. alpha is transferred from source to
    // the destination
    System.out.printf("Result alpha: 0x%02x\n", dstAlpha);
    if (srcAlpha != dstAlpha) {
        throw new RuntimeException("Test failed!");
    }
    System.out.println("Test passed");
