Bug#1082830: unpaper: (data loss) Half the content is lost when the source data is 600 dpi
Package: unpaper
Version: 7.0.0-0.1
Severity: normal
Tags: upstream
X-Debbugs-Cc: debbug.unpaper@sideload.33mail.com
Control: forwarded -1 https://github.com/unpaper/unpaper/issues/230
When the input file is 600 dpi, the leftmost 25% and rightmost 25% of
the content is truncated. Only the middle 50% survives unpaper. My
command was simply:
$ unpaper -t pbm source.pgm target.pbm
I also tried adding --dpi 600, which had no effect.
This defect has already been reported upstream. This bug report is
filed to indicate that version 7.0.0-0.1 of the debian pkg is
affected. This is also to add information, as the original bug report
demonstrates the problem with TIFF files, while my experience shows
that the bug also manifests in a PGM→PBM conversion.
