I am building a Windows form that has a diagram that needs to change to whatever
color the user picks.
The diagram was taken from a screen shot and placed in Microsoft Paint, where I tried
to do a Windows form grey outline and then use transparent colour in the middle.
The idea was to change the background color of the picture box so that it would come through
the transparent part of the diagram, hence appearing to change color.
The problem is the MS Paint doesn't appear to have transparent color, only white.
Any help on this would be greatly appreciated
