Jay Berkenbilt 31b45b0fd4 Fix logic error with Tf when generating appearances (fixes #655) 2022-02-18 13:46:35 -05:00
Jay Berkenbilt a478cbb6dc Silently/transparently recognize UTF-16LE as UTF-16 (fixes #649) 
The PDF spec only allows UTF-16BE, but most readers seem to accept
UTF-16LE as well, so now qpdf does too.

Jay Berkenbilt fbd3e56da7 Ignore -- at the top level arg parser (fixes #652) 
This was unintended behavior that was added back for backward
compatibility. It is intentionally undocumented.

Jay Berkenbilt cb769c62e5 WHITESPACE ONLY -- expand tabs in source code 
This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.

In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.

Jay Berkenbilt 750aca5b94 First increment of improving handling of weak crypto (fixes #358) 2021-11-11 12:24:15 -05:00
Jay Berkenbilt f45dacf4cb Make recovery logic flexible about where objects end (fixes #573) 
Don't assume endobj is at the beginning of the line. This means we are
looking at tokens for every line, but the odds of n n obj appearing in
the middle of the object are likely much lower than endobj not being
at the beginning of the line or missing entirely. This will probably
have a negative impact on recovery time for very large files.
Hopefully it will be worth it.

using CopyForeignObject.

only come from the document dictionary.
