Question

For instance, here is sample JPEG which I cannot SAVE (!) but can read (e.g. find out width and height) using standard dotnet classes. Original file:

http://dl.dropbox.com/u/5079317/184809_1_original.jpg

After saving same image in windows image editor, all works great:

I noticed this bug long time ago but it wasn’t major problem. But in current project I have thousands of such images and i really need some kind of solution.

Which 3rd party libraries could be used?

Here is how I am reading:

public ImageFile SaveImage(HttpPostedFileBase file, string fileNameWithPath, bool splitImage, out string errorMessage)
{
  try
  {
    using (var stream = file.InputStream)
    {
      using (Image source = Image.FromStream(stream))
      {
        return SaveImage(source, fileNameWithPath, splitImage, out errorMessage);
        // which actually do source.Save(fileNameWithPath, ImageFormat.Jpeg);
        // Exception: A generic error occurred in GDI+.
      }
    }
  }
  catch (Exception e)
  ...
}

Answer 1

Resizing of original image to same size solves problem:

Image img2 = FixedSize(source, source.Width, source.Height, true);
img2.Save(path, ImageFormat.Jpeg);
