Hi rana.anees,

Yes it is possible. Below a code snippet how to draw a rectancle on a mutable image.

Image newImage,sourceImage;

public void initializeImage()
{
	try {
		 sourceImage = Image.createImage("/image.png");
	     } catch (IOException e) {}
	
	 newImage = Image.createImage(sourceImage.getWidth(),sourceImage.getHeight());
	 
	 Graphics imageGraphics = newImage.getGraphics();
	 imageGraphics.drawImage(sourceImage, 0, 0, 0);
	 imageGraphics.setColor(0xff0000);
	 imageGraphics.fillRect(10, 10, 40,40);
		 
	 sourceImage= null;
}
	
protected void paint(Graphics g)
{
	g.drawImage(newImage,55,55,0);
}

thanks for reply.one more question can we use key press Fuction class which is extended from form

Hi rana.anees,

If you mean the Displayable and command actions yes they can be used with a form. If you want to receive key and pointer events directly you would have to use a Canvas.
