How can I remove drawn lines?

For example, if I use drawRect() onto my world image, how can I remove that rectangle without affecting the rest of the world image? A solution I've thought of is to have an actor object that is simply a GreenfootImage with a rectangle drawn on it. I could then add and remove the rectangle to the world image that way. However, this way is extremely clumsy and I'd much rather have something cleaner.

How badly does it mess up your background? that is, do you have a flat color for the background or is the rectangle placed over multiple different colored pixels in the background without any regular pattern? Why would you say it would be clumsy to add and remove an actor with an image with the rectangle on it? It would not be much easier to save the area that the rectangle will be at and redraw it later.

The rectangle is simply drawn on the background. There isn't any other "messing up" really. Is saving and redrawing my only alternative?

If you do not have an image in the world background that is being altered in any way. you could draw the rectangle again in the color of the background of the world (to erase it).

Haha, yeah I'll definitely just stick to wrapping the image into an Actor object. I appreciate the time and effort though!
