On the real studio forums there was a request for code to draw a rounded rectangle with dashes. Interesting problem. So this is my little project implementing some source code sources I found online. Source web sites given in project. The rectangle is shown in the bottom right of the screen shot. Came out nice if I do say so! I added an ellipse and antialias Wu line too. These are all drawn to a picture buffer graphics context writing to the individual pixels. Runs pretty fast!
I’m using a call to Drawline with the same x and y locations, essentially like calling a plot pixel call. This technique doesn’t seem to work on my tests with Vista. I think you need to make sure GDI is enabled, might be a bug, again, not sure. Works like butter on a Mac.
