Losing Exif tags on save.

I am now evaluating Leadtools V16.net. I have run across a roadblock. Whenever I save a .jpg, all the exif tags go away.

    gImage = gCodecs.Load("c:\tmp1.jpg")
    gCodecs.Options.Save.Tags = True
    gCodecs.Save(gImage, "c:\tmp1.jpg", RasterImageFormat.ExifJpeg, 24)

Surely I don't have to make a call to rastercodecs.readcomment for each tag do I? That would be 111 extra disk accesses every time I load a file (for typical photo image). Isn't there a better way to do this?

You will need to loop, but you can reduce disk access as follows:
1. Load the file into a System.IO.MemoryStream object.
2. Loop using RasterCodecs.ReadComment() Method that works with streams.
3. After each iteration in the loop, you should rewind the stream to its beginning.
