I have been working with the the libtiff libary (v3.4) and noticed that the tif_fax3.c decode stuff (Fax3Decode1D, Fax3Decode2D, Fax3DecodeRLE, and Fax4decode) return -1 or 1.

The fax2tiff tool does the call like this:

ok = (*tifin->tif-decoderow)(blah).

Then the return code is check like this:

if (!ok) {
    blah
}

If you return -1 or 1, I don't think that ok will ever be false. :) All of the other compression routines return 0 or 1. So I don't think this is right.

If I am wrong, please let me know.

You are correct; I'll fix fax2tiff.
