How exactly do I do rectangular to polar conversion in Paint.net??
My version only shows one option [Effects > Distort > Polar Inversion]. I don't see an option for rectangular to polar.
Also, what does this statement mean?
"2.Add you picture up side down in the 1/4 bottom part of the image (for 800x800, your image should be placed at 0,600 to 800,800)."
I understand that I need to resize to a square shaped image, but what does the rest of that mean?
