Run the following code in a 256 color mode Windows NT. The image
is not transparent as it should be.

Display display = new Display();
Shell shell = new Shell(display);
RGB rgb = new RGB(230, 226, 221);
Color color = new Color(display, rgb);
Image img = new Image(display, 20, 20);
GC gc = new GC(img);
gc.setBackground(color);
gc.fillOval(0, 0, 20, 20);
gc.setBackground(display.getSystemColor(SWT.COLOR_RED));
gc.fillOval(0, 0, 20, 20);
gc.dispose();
ImageData data = img.getImageData();
data.transparentPixel = data.palette.getPixel(rgb);
//ImageData data = new ImageData("D:\\eduardo\\desktop\\ide\\project_resources\\Eclipse JFace\\org\\eclipse\\jface\\dialogs\\images\\title_error.gif");
Image image = new Image(display, data, data.getTransparencyMask());
Label label = new Label(shell, SWT.NONE);
label.setBackground(color);
shell.setBackground(color);
label.setSize(100, 30);
//label.setText("ERROR");
label.setImage(image);
label.setSize(100, 100);
shell.open();

while (!shell.isDisposed()) {
	if (!display.readAndDispatch()) display.sleep();
}

NOTES:

	McQ (11/06/2001 9:18:43 AM) -
		Do we still fake transparency for labels by setting the "transparent" pixels
		to the background color? If so, this could just be a failed closest match issue.
