Thanks for that. It gives a little more detail than tiffdump. I looked at a number of files generated from the one original file - the original compressed file, an 8-offset uncompressed file, the original file copied (which recompresses it?), a compression of the uncompressed 8-offset (which is not forced to 8-offset), and a compressed copy forced to 8-offset. I come up with the following: The files are identical except for two things - file size, and offsets/counts - the second being expected. The strip offsets for the valid and invalid compressed files match exactly, as do their stripbytecounts (i.e., apart from starting in different places strip offsets are no different.). All the file sizes are different though - with the invalid being the smallest of the compressed files. Is this a path to investigate? I am going to have a closer look at compression but this is getting out of my league. Cheers Antoine ps. I might try putting rowsperstrip to a huge value and see what that does...
