Hello,
I probably wouldn't do this from OnPaint
as this event can be frequently called and could slow your application down if you put expensive code in it.
You could probably use something similar to the following to create a copy of the source image, apply your custom overlay, and then save it to a file.
using (Bitmap copy = new Bitmap(imageBox.Image))
{
using (Graphics graphics = Graphics.FromImage(copy))
{
// draw overlay
}
copy.Save(@"t:\temp\copy.bmp", System.Drawing.Imaging.ImageFormat.Bmp);
}
Hopefully this gives you a starting point!
Regards;
