Strange GDI+ error
-
I have a gif file, 256 colors, created with Paint Shop Pro. I do // Load the bitmap Bitmap myBitmap = new Bitmap ("toto.gif"); // Cut it Bitmap frame = myBitmap.Clone(Rectangle); // Save individual frames frame.Save("Frame1.gif", Imaging.PixelFormat.Gif); It works OK. Latter, I want to load the saved frame // Load the frame again Bitmap frame = new Bitmap("frame1.gif"); This works also. But, if I try to save it again frame.Save("Frame2.gif"); I got an external exception in InteropServices, telling me there was a problem with GDI+.dll. Anybody had the same problem?

I'm not sure exactly what you're trying to do (which may help to understand the problem and help you solve it), but take a look at the
Image.SaveAddmethod (whichBitmapwould inherit, of course) to see how to save individual frames of an animated GIF, which I'm guessing is what you're trying to accomplish.Microsoft MVP, Visual C# My Articles

Search on Google groups, I had the same problem a few years back. Sorry I cant recall the resolution though :( top secret

I have a storyboard, a single image that contains several frames. My program cut this storyboard in individual frames, of variable size. I now want to save these individual frames in separate files. This part works. The gif are indeed saved. Later I need to make copies of some of these files, after I've done some processing on memory on them. So I start by loading the individual frames doing Bitmap bitmap = new Bitmap("Frame1.gif"); // Then some processing // Then I save it again bitmap.Save("Frame1.gif", PixelFormat.gif); And there it crashes. I have tried to do the save immediatly after the load, in case my processing was messing something, but it still doesn't work. Conclusion: I cannot save a bitmap immediately after I load it? :confused:

That is weird, and I frankly don't know the answer to that. But there is a better, more efficient way of copying files anyway:
