Examples with CompositeContext java.awt.CompositeContext used on opensource projects

Example 1 with CompositeContext

use of java.awt.CompositeContext in project jdk8u_jdk by JetBrains.

the class Bug7049339 method main.

public static void main(String[] argv) {
    int x = 100, y = 100;
    BufferedImage src = new BufferedImage(x, y, BufferedImage.TYPE_INT_ARGB);
    BufferedImage dst = new BufferedImage(x, y, BufferedImage.TYPE_3BYTE_BGR);
    Graphics2D dstg2d = dst.createGraphics();
    dstg2d.setComposite(new Composite() {

        @Override
        public CompositeContext createContext(ColorModel srcColorModel, ColorModel dstColorModel, RenderingHints hints) {
            return new CompositeContext() {

                @Override
                public void compose(Raster src, Raster dstIn, WritableRaster dstOut) {
                // do nothing
                }

                @Override
                public void dispose() {
                }
            };
        }
    });
    Shape clip = new Ellipse2D.Double(x / 4, y / 4, x / 2, y / 2);
    dstg2d.setClip(clip);
    // This will throw a RasterFormatException if the bug is present.
    dstg2d.drawImage(src, 0, 0, null);
}

Example 2 with CompositeContext

use of java.awt.CompositeContext in project jdk8u_jdk by JetBrains.

    * provided by an application
    */

    } else {
        dstIn = dstRaster.createChild(x, y, w, h, 0, 0, null);
        dstOut = dstIn.createCompatibleWritableRaster();
    }
    compCtxt.compose(srcRaster, dstIn, dstOut);
    if (dstRaster != dstOut && dstOut.getParent() != dstRaster) {
        if (dstRaster instanceof WritableRaster && atile == null) {
            ((WritableRaster) dstRaster).setDataElements(x, y, dstOut);
        } else {
            ColorModel cm = sg.getDeviceColorModel();
            BufferedImage resImg = new BufferedImage(cm, dstOut, cm.isAlphaPremultiplied(), null);
            SurfaceData resData = BufImgSurfaceData.createData(resImg);
