Der nachfolgende Code zeigt, wie JPEG Grafiken (und ebenso auch andere Formate) verlustlos rotiert werden k��nnen:



Image i = Image.FromFile(this.imageFilename);

ImageCodecInfo usedIC = this.GetEncoderInfo("image/jpeg");



System.Drawing.Imaging.Encoder encoder = 

  System.Drawing.Imaging.Encoder.Transformation;



EncoderParameters encparams = new EncoderParameters(1);

EncoderParameter encparam = 

  new EncoderParameter(encoder, 

    (long)EncoderValue.TransformRotate270);

encparams.Param[0] = encparam;



i.Save("filename.jpg", usedIC, encparams );



i.Dispose();

i = null;

GC.Collect();
