I havent tried it..but the cautionary note that " It is not always possible to do so due to decompression constraints" scares me. I also read on the archive that "that *strip* *chopping* only works for uncompressed IFDs.". How common(or uncommon) is this? When would one use compressed IFD's?

 The tiff's we get can be compressed or uncompressed formats and we have to

I believe that libtiff has a strip-chopping build option. This may be in the build defaults. The strip-chopping option should break long strips into multiple small strips/scanlines if possible. It is not always possible to do so due to decompression constraints. Does this feature not work for you?
