Create a .gif file?

Question

How do I create very simpel 1cm x 1cm colored .gif file? Can someone plz tell?

Answer 1

The simple way is to use method
public Image createImage(int width, int height)of any java.awt.Component you use. Then, you can use method
public Graphics getGraphics()of the created image to get Graphics object to draw into the image.
(Note, that you cannot draw to an image, which is not created by createImage method!). For example:
import java.awt.*;
public class MyApplet extends java.applet.Applet {
  Image image;
  public void init() {
    image = createImage(100,100);
    Graphics g = image.getGraphics();
    g.drawLine(0,0,100,100);
  public void paint(Graphics g) {
    g.drawImage(image, 0, 0, this);
}It is also possible to use java.awt.image.MemoryImageSource class to create an image from binary data (see API doc).
