I'm trying to implement an JPEG/EXIF parser using libtiff. Separately, I am able to extract the EXIF block from the source jpeg image, and I can see that it has the proper "II" preamble for TIFF. I can also see the textual EXIF data within the block.
FYI, there is a simple EXIF parser included in ImageMagick & GraphicsMagick. These are open source packages.
