Ordinarily qpdf tries to decode streams that it thinks it + can decode based on the filters, and if there ends up being an + error when actually trying to do the decode, the stream data + is truncated. This flag causes qpdf to actually read the + stream fully before deciding whether to filter the stream. + This option will slow qpdf down since it will have to read the + stream twice, but it allows raw stream data to be preserved in + cases where the decoding of the stream would fail for some + reason. This may be useful in working with some damaged files. + </para> + </listitem> + </varlistentry> + <varlistentry> <term><option>--qdf</option></term> <listitem> <para> |
