I need to convert a series of jpeg images to a single, multi-page tiff. More details and discussion can be found at
viewtopic.php?f=1&t=24077.
Thanks

IM relies upon the tiff delegate library. So you really need to take that up with the tiff development team. If it is included in libtiff, then perhaps IM can utilize it. But until then, it is not likely an IM issue as far as I understand. Is that functionality in libtiff already?

Umm maybe... I just don't know enough about programming or either spec (jpeg or tiff) to say one way or the other. [tiff-x.x]/libtiff/tif_jpeg.c seems to have everything pertaining to jpeg compression. There are a few parts that appear to my naive and, at this point, very wishful mind to suggest that the functions needed to write jpeg-compressed image data directly into a tiff file are already there. The file looks to me to be well laid out and well commented - I just don't know what any of it means. If this really is a problem beyond the scope of the IM devs, though, I totally understand and would be happy to pass this along to the libtiff guys or whatever other parties this may concern.
Thanks
