I'm not talking puritanism. I'm talking functionality. I'm talking from a very pragmatic point of view. Did you think that very basic property of TIFF was designed in just for the sake of puritanism? > My personnal advice would be to go with the "only images taken with > the camera are supported" line, but put an *, and an explanation of You have ignored large part of the point I tried to make. - Where is it said or written or even observed that the TIFFs build by camera's all, or even most of the time, have their first IFD at offset 8? You will no doubt agree that is necessary for the description to make any sense at all, so if you know this for a fact, please tell us your source or experience, I'm eager to learn. - I thought I made sense when I assumed that if there needs to be a fixed position of the first IFD, for support by Katrina's module, then most probably either a) she totally forgot about all other data blocks, totally ignored lots of other options like multiple strips and tiles which are most common, or either b) imposes restrictions to the position of these too. That adds to the first point I tried to make, and generally looks suspicions, and leads to me believe that probably she supports only the TIFFs made she has tested sofar, by the particular camera sofar. If any of this does not make sense, I would like to learn why. If it does make sense, the logical conclusion is that the description 'only images taken with the camera are supported' is not a good description at all, and should be replaced with what I proposed, being 'only images taken with this or that particular version of this or that particular camera seem supported'.
