Loading/saving while preserving EXIF/IPTC information?

I'm trying this simple operation:

BitmapViewer1.Bitmap.Load(myFilePath)
ApplyTransform(New Aurigma.GraphicsMill.Transforms.RotateAndFlip(System.Drawing.RotateFlipType.Rotate90FlipNone))
' where apply transform is same as in demo code
BitmapViewer1.Bitmap.Save(myFilePath)

Now, the operation works fine, as in the image is rotated and saved to file.

However, all the EXIF and IPTC information from the original file is gone! Is there any way to have this operation preserve the image metadata? (I am trying this with jpeg files)

The example given here shows that I have to load the bitmap and then save it with jpegWriter.

I have some other library that can change IPTC without processing the image, so I assume it's not technically impossible.

Thanks,
