   "The color with which a image from createImage() is filled is not correct"


Name: dgC58589 Date: 12/08/97


The color with which a image's background is
filled with when created using createImage()
is not consistent.

1. If the Panel's background is set with
Color.xxxx, the image's background is xxxx.

2. If the Panel's background is set with
SystemColor.xxxx, the image's background is black.

Running the program below without a param would
show case 1 and with param as case 2.
-------------------------------------------

import java.awt.*;

public class ColorBug extends Panel {
    public void paint(Graphics g) {
        Image temp = createImage(100, 100);
        if (temp != null) {
            g.drawImage(temp, 0, 0, null);
            //IF setBackground(SystemColor.window) is used,
            // this draws a black rectangle
            //BUT IF setBackground(Color.red) is used,
            // this draws a red rectangle
        }
    }

    public static void main(String[] args) {
        Frame f = new Frame();
        ColorBug bug = new ColorBug();
        if (args.length > 0)
            bug.setBackground(SystemColor.window);
        else
            bug.setBackground(Color.red);
        f.add(bug);
        f.setSize(200, 200);
        f.show();
    }
}

------------------------------------

In my opinion, the way it works with Color.xxx,
is correct. Then I would not need to fill the
image created with the background color of the
Panel.
