System.ArgumentException when calling MediaLibrary.SavePicture()

My code looks like this:

String filename = Utils.GetNextFilename();
MediaLibrary library = new MediaLibrary();
library.SavePicture(filename, corrected_image);

And in the SavePicture() call, I get the following:

An unhandled exception of type 'System.ArgumentException' occurred in Microsoft.Xna.Framework.dll

Additional information: Value does not fall within the expected range.

But I'm not sure why.

Solution

  • Okay, I figured it out. I must reset the stream:

    String filename = Utils.GetNextFilename();
MediaLibrary library = new MediaLibrary();
corrected_image.Seek(0, 0);                      // <-- The fix.
library.SavePicture(filename, corrected_image);
