You can create a new
Bitmapfrom a file path or aStream. UseGraphics.FromImageto get aGraphicsobject for that image. Keep in mind, however, that GIFs are indexed images and require a palette. If you're using different colors other than what exists in teh palette, you'll need to generate a new palette from the existing one and add the colors you need.Microsoft MVP, Visual C# My Articles
