I like that you got the gist of it in a succinct line. This is similar to one of my intermediate steps as I was writing the script. I decided against it because a it loses too many sharp details, b I wanted to make the color selection obvious so it could easily be changed, and c I wanted to floodfill from all the edges, not just the top-left corner.
There may be other things I'm forgetting right now. I'm going to take a wild guess that "fmw" stands for Fred M. If so, greetings, Dr. To anybody who doesn't know who he is, he wrote some of the seminal research in computer graphics starting in the 's. Everyone should check out his amazing conucopia of ImageMagick shell scripts at fmwconcepts.

That should work as long as the non-anti-aliased pixels are not shades of gray. Unfortunately it requires you to examine every pixel and that will be slow. The best solution is to draw the original image with a transparent background.
Before you start drawing, clear the image with the Transparent color. Then draw on it. In that case, the anti-aliased pixels will be semi-transparent like the result of the second option. Of course, this only works if you have control over the original drawing.
In other words, if you draw it. Many colors have a certain amount of white in their composition. In my example I used black, but for other colors it is very difficult to detect only the edges and replace the white with its transparent equivalent of pen color.
Also, if I clear the image with the Transparent color, behind the image is the color of the Form that makes things go wrong. Use transparency when drawing with anti-aliasing in C. I'm still not sure how you're drawing. Are you drawing the original image? Or did you get it somewhere? If you got it somewhere so you don't have control over it and it has lots of anti-aliased colors, then I don't think there is an easy solution for you.
You could convert every pixel within about 3 pixels of a transparent pixel. That would be hard and erode your image so it would become smaller, but it might provide a slightly better result. Overall, however, you may just be stuck without a good solution.
Thank you Rod. Finally I save the drawing as. Net editor. This example works with colored images. The MakeTransparent method makes all of the pixels of a given color transparent.
