How can I generate GIF images in .NET?

Question

Is there a .NET library I can use to programmatically generate my own GIF images?

At a minimum I'd like to build it pixel-by-pixel. Better would be support for text and shapes.

Here's an example of what I'm trying to do. I mocked this up in Photoshop…

What do you recommend?

Answer 1

Bitmap bmp = new Bitmap(xSize, ySize, PixelFormat.Format32bppArgb);
using (Graphics g = Graphics.FromImage(bmp)) {
  // Use g and/or bmp to set pixels, draw lines, show text, etc...
}
bmp.Save(filename, ImageFormat.Gif);
