Java etc.

Diese Methode macht aus einem javax.swing.Icon ein java.awt.Image Objekt:

public Image iconToImage(Icon icon) {
if (icon instanceof ImageIcon) {
return ((ImageIcon)icon).getImage();
}
else {
int w = icon.getIconWidth();
int h = icon.getIconHeight();
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();
GraphicsConfiguration gc = gd.getDefaultConfiguration();
BufferedImage image = gc.createCompatibleImage(w, h);
Graphics2D g = image.createGraphics();
icon.paintIcon(null, g, 0, 0);
g.dispose();
return image;
}
}
