goImage Background color

GoDiagram (6 and previous)

Just wondering if you can think of a way to change to backcolor of an image used in a goIconicNode using code. For example if I put an image on a web page I can code something like:
Image1.BackColor = System.Drawing.Color.Red;
Is there a way to do that to the iconic node image?
Thanks,
Mark

Your image has transparent pixels in it, right?
I suppose you could have a GoRectangle behind it colored the way you want.
Or you could override GoImage.Paint to first fill the area of the image with your desired background color.

I’m going to echo Walter’s earlier comment. Why not just use transparent background in your icons? Once you do that, putting a color behind the icon is easy. (See the 5-pointed star in Demo1…)
