Example 1 with RGBImageFilter

use of java.awt.image.RGBImageFilter in project adempiere by adempiere.

the class PDFViewerBean method createActionButton.

protected JButton createActionButton(Action action, String text, String image, String tooltip) {
    final ImageIcon icon = new ImageIcon(getClass().getResource(image));
    final double colorFactor = 0.9;
    final RGBImageFilter filter = new RGBImageFilter() {

        public int filterRGB(int x, int y, int rgb) {
            final int alpha = (rgb >> 24) & 0xff;
            final int red = (rgb >> 16) & 0xff;
            final int green = (rgb >> 8) & 0xff;
            final int blue = (rgb) & 0xff;
            return ((int) (alpha * colorFactor) << 24) | ((int) (red * colorFactor) << 16) | ((int) (green * colorFactor) << 8) | ((int) (blue * colorFactor));
        }
    };
    final ImageIcon darkerIcon = new ImageIcon(Toolkit.getDefaultToolkit().createImage(new FilteredImageSource(icon.getImage().getSource(), filter)));
    final JButton result = new JButton();
    result.setAction(action);
    result.setText(text);
    result.setIcon(darkerIcon);
    result.setBorderPainted(false);
    result.setHorizontalTextPosition(SwingConstants.CENTER);
    result.setVerticalTextPosition(SwingConstants.BOTTOM);
    result.setMnemonic(0);
    result.setToolTipText(tooltip);
    final Dimension dim = result.getPreferredSize();
    result.setMaximumSize(new Dimension(32, dim.height));
    result.addMouseListener(new MouseAdapter() {

        public void mouseEntered(MouseEvent me) {
            result.setBorderPainted(true);
            result.setIcon(icon);
        }

Example 2 with RGBImageFilter

use of java.awt.image.RGBImageFilter in project intellij-community by JetBrains.

the class ColorBlindnessTest method compareFilters.

private static void compareFilters(ImageFilter one, ImageFilter two) {
    RGBImageFilter rgb1 = (RGBImageFilter) one;
    RGBImageFilter rgb2 = (RGBImageFilter) two;
    for (int i = 0; i < 0x01000000; i++) {
        assertEquals(rgb1.filterRGB(0, 0, i), rgb2.filterRGB(0, 0, i));
    }
