There was a discussion recently (starting at May 5) on Fax3 images that produces error messages like

Fax3DecodeRLE:c:test.tif:Line length mismatch at scanline 0 (got 167444480,
expected 12058624),
Fax3DecodeRLE:c:test.tif:Bad code word at scanline 5 (1572864),
Fax3DecodeRLE:c:test.tif:Premature EOL at scanline 5 (got 1572864,
expected 12058624),

I asked the originator of this thread to send me some samples, as I was interested in how the PostScript decompression filters would work with these images.

My test then showed that the PostScript stuff produced no errors at all; I then handled the images with libtiff (V3.3beta, still) and got no error either.

So I have the suspicion that the errors might be due to default values for tags not explicitely defined.

Any ideas?
