I've included 2 versions, one uses Span, which is slightly more performant when cropping to a smaller image. (Other formats could work as long as 1 pixel is stored as 4bytes) Just keep in mind 32bpp is the only format the methods support. Graphic.DrawImage(OriginalImage, new SD.Rectangle(0, 0, Width, Height), X, Y, Width, Height, SD.GraphicsUnit.Pixel) įor anyone willing to use "unsafe" code, you can achieve much better performance than the standard method, and even better if you are using Bitmap.Clone().

I tried Nicks solution, but i needed 29,4 sec to "extract" 1195 images of an atlas file. I was looking for a easy and FAST function with no additional libary to do the job.
