Use the Rectangle Select tool and, holt the SHIFT key to draw a square about 100 x 100 pixels. Choose the Move Selection tool and, right-click to rotate the square to 45 degrees. Move the selected square to the bottom right of your canvas so that it is only covering a small potion in the corner measuring 20 x 20.
I'm a new person to paint.net. I have had it only about 2 months and have learned a lot with all the tutorials; HOWEVER, I am at a loss with the above step.
I can't get this part to work. It moves the entire film strip, not just the box I created when I try to rotate the box. Should I create another layer while doing this?
