Bug Description
When /usr/lib/
WARNING: ./file.pdf (file position 101510): error decoding stream
data for object 39 0: stream inflate: inflate: data: incorrect data check
ERROR: Exception: stream inflate: inflate: data: incorrect data check
Example PDF (attached a copy, too) : https:/
Adobe Pro doesn't seem to have any issues with these PDFs, so the error is probably not fatal for processing the file.
To post a comment you must log in.
Object 39 is an image; but even Object 4 (the content stream of the first page; obj 93 *is* used on that page) has such a decompression error.
Ghostscript prints:
warning: ignoring zlib error: incorrect data check
So probably libqpdf (which is used for the very low-level pdf stuff in pdftopdf) should also handle this as warning instead of as error?
