Created an attachment (id=611) [details] TIFF file created by PDFBox I get this with ImageMagick: convert.exe: Premature EOL at line 0 of strip 0 (got 0, expected 1728). `Fax3Decode1D' @ warning/tiff.c/TIFFWarnings/857. The file is created by taking a CCITT stream from a PDF and attaching a tailored TIFF header to it. IrfanView, ImageMagick and GIMP (tools that use libtiff) can't display this file, Microsoft tools can. The data is CCITT G3 encoded. I wonder whether the header is wrong, the data is wrong or whether the decoding by libtiff is wrong. Or is it so that EOLs are allowed in CCITT G3 and PDF, but not in TIFF? There's a quote in the TIFF spec "No EOL code words are used" and in the PDF spec "The CCITTFaxDecode filter always accepts end-of-line bit patterns". I can't tell what version of libtiff is used, but it is probably not too old, I downloaded ImageMagick today.
Bugzilla is no longer used for tracking libtiff issues. Remaining open tickets, such as this one, have been migrated to the libtiff GitLab instance at https://gitlab.com/libtiff/libtiff/issues . The migrated tickets have their summary prefixed with [BZ#XXXX] where XXXX is the initial Bugzilla issue number.
