Default Is it possible to undraw an object?

In order to move an object on screen, rather than clear the screen and redraw everything, is it possible to undraw, i.e. draw the same object but XOR so that it wipes out, then draw it in a different position?

My difficulty in trying to test this is that I can find how to write a pixel but not to read one.

Any assistance appreciated.
