Hi,


My question doesn't concern the tiff library directly but maybe someone
can help me.
I'm looking for a way to decompress files produced by the latest DCS
kodak cameras (DCS520-DCS560). This files contain a standard tiff header
plus a  private TAG containing raw data from the CCD. If you open such a
file in photoshop you are only able to view a thumbnail of hiresolution
image.
My concern is to extract the hiresolution data from the private tag,
this sounds rather complicated since data seem to be compressed with a
non destructive algorithm (LZW ? ZIP? ....) but should be possible.
Kodak provides a SDK to extract image data from this kind of image but
unfortunatelly some process, that I want to avoid, occur during the
extraction.

Any help would be greatly appreciated,

Bruno
