It becomes apparent that answers like this are why this list seems to be dead...

If you had read the original question, you would know that I have looked at the code for tiffcp and found it wanting for what I desire. I want to be able to do

the conversion in memory, without the intermediate file.

The code for the g4 compression within libtiff is somewhat undocumented, and I hoping to have this clarified. was

In general, as ever, RTFQ...

As in tiffcp when changing compression: Open input file, output file and read scanlines from input file and write them to output file.

In general: RTFM!
