Hi all, I'm reading a tiled-tiff-jpeg coded image. It's coded with ttn2-type jpeg. I'd like to be able to read a compressed tile (without decompressing), and write that tile out as a JFIF. What's the best way to do this?
At the moment I'm decompressing tiles, then passing them back through the jpeg library again to make a JFIF, which is just daft. Many thanks for any help,
