A Basic function on things like paint, powerpoint, and word etc is being able to have a picture without the square of white that comes with it. Essentially Im drawing symbols and then layering images on each other but the White square gets in the way. All I want is the line drawing as an image. It looks naf at the moment. I need transparency of the background as shown in the picture..How do I do that ? If not why i this not a function?
