I am trying to (using 3.5.7) open a tiff which has no compression and compress using

the JPEG compression algorithm. I have tried to view the code in tiffcp.c but it is

convoluted, in trying to handle all kinds of possibilities. In using tiff apis previously, most

things I have wanted to try ended up being easy. Can somebody point me in the right

direction in terms of how I open a TIFF file, change the compression tags, and then

rewrite the directory and close the tiff file?

Thanks,
Carl J. Collin
