I would like to be able to rotate a jpeg and write it back to the same file. My code looks something like this:

Code:

Aurigma.GraphicsMill.Codecs.LosslessJpegTransform trans = new Aurigma.GraphicsMill.Codecs.LosslessJpegTransform();

trans.Open(item.Pidl.Path);
trans.WriteRotated(item.Pidl.Path, System.Drawing.RotateFlipType.Rotate90FlipNone);
trans.Close();

When I get to the WriteRotated command, an error is thrown because the file is being used by another process (trans.Open). I'm sure I can figure out a work around, but I just wanted to make sure I wasn't missing a step.

Thanks,
Brad

Dmitry

Hello Brad,

Unfortunately you cannot load and save an image from/into the same file. In your case you should save your result image into temporary file and then rename it to file name which you need.

Sincerely yours,
Dmitry Sevostyanov.
