Thanks guys! I appreciate the time you took!
Another question I have regarding the .PDN format. Is it possible to, when I'm done with the image, merge the layers and 'save as' a .jpg image to shrink the file size a little bit? I know it's impossible to keep all the individual layers without saving it in a .PDN format, but I'll probably need to shrink the file down when I'm done with it for the purpose of using it on a different forum.
I apologize at the stupidity of this question, I am very new to Paint, and my question is, when making a basic black rectangle on a white background, how do you rotate that rectangle? Again, I apologize at the stupidity of this question.
