Bruno P. Kinoshita commented on IMAGING-97:
-------------------------------------------
There are at least five markers ignored by the JpegDecoder, and that I think
would have to be handled in order to get valid/similar output. I compared the
HTML dump of exiftool, and the ImageIO and Imaging files are very different. I
thought this would be a one day task, but it seems it would take a lot longer
to implement and test it well. :(
