Example 1 with Transparency

use of java.awt.Transparency in project netbeans-rcp-lite by outersky.

the class ImageUtilities method doMergeImages.

private static final ToolTipImage doMergeImages(Image image1, Image image2, int x, int y) {
    ensureLoaded(image1);
    ensureLoaded(image2);
    int w = Math.max(image1.getWidth(null), x + image2.getWidth(null));
    int h = Math.max(image1.getHeight(null), y + image2.getHeight(null));
    boolean bitmask = (image1 instanceof Transparency) && ((Transparency) image1).getTransparency() != Transparency.TRANSLUCENT && (image2 instanceof Transparency) && ((Transparency) image2).getTransparency() != Transparency.TRANSLUCENT;
    StringBuilder str = new StringBuilder(image1 instanceof ToolTipImage ? ((ToolTipImage) image1).toolTipText : "");
    if (image2 instanceof ToolTipImage) {
        String toolTip = ((ToolTipImage) image2).toolTipText;
        if (str.length() > 0 && toolTip.length() > 0) {
            str.append(TOOLTIP_SEPAR);
        }
        str.append(toolTip);
    }
    Object firstUrl = image1.getProperty("url", null);
    ColorModel model = colorModel(bitmask ? Transparency.BITMASK : Transparency.TRANSLUCENT);
    // Provide a delegate Icon for scalable rendering.
    Icon delegateIcon = new MergedIcon(image2Icon(image1), image2Icon(image2), x, y);
    ToolTipImage buffImage = new ToolTipImage(str.toString(), delegateIcon, model, model.createCompatibleWritableRaster(w, h), model.isAlphaPremultiplied(), null, firstUrl instanceof URL ? (URL) firstUrl : null);
    // Also provide an Image-based rendering for backwards-compatibility.
    java.awt.Graphics g = buffImage.createGraphics();
    g.drawImage(image1, 0, 0, null);
    g.drawImage(image2, x, y, null);
    g.dispose();
    return buffImage;
