Hi All,

I have a need to convert JPEG images to TIFF, ideally without having to decompress and then recompress the JPEG data. I am already using LibTIFF in my application; is there some way I can extract the compressed JPEG data out of a .JPG file (using libjpeg for instance) and shoehorn it into a JPEG compressed TIFF using LibTIFF, and if so could somebody please point me in the right direction? Apologies if I've missed an obvious answer to this question.

Many thanks,
