Hi all Okay I'm looking for a bit of help polishing up a script. I was inspired by to try and find a simpler way to render a rounded corner semi-transparent background using a semi-transparent gdi pen (if there was a semi-transparent brush, life would be so much easier). I think I have it but perhaps my math skills are not up for the challenge that corners provide. I showed 2 ways I tried in the below GUI. Both are less than perfect. Can someone help me figure out how to draw the corners?
