By combining --linearize with --compress-streams=n, we ensure that no
new compressed data will appear in linearized output, which makes the
output independent of zlib's output. There are other tests to ensure
that linearization works correctly with compression. This commit
involves changing some test outputs and test code as well just
updating test suites.
Switch output to QDF for easier diffing
Simplify input image
Reduce decimal places
This works around an issue were, for certain versions, the mingw32
tests failed because of irrelevant floating point rounding issues in
the test output.
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.
Change "-" to "--" for named parameters.
Remove spaces inside "[ option ]" for optional parameters.
Fix "pdf-mod-info --dump file" to match usage message.
The QPDF_String::getUTF8Val() method was not treating strings that
weren't explicitly Unicode as PDF Doc Encoded. This only affects
characters in the range 0x80 through 0xa0.
Adding a trailing newline in content normalization damages files whose
contents are split across streams in the middle of tokens. Let
QPDFWriter add the newline with the indicator to ignore the newline,
which it already does. This changes the way some qdf files look.
If NO_GET_ENVIRONMENT is #defined at compile time on Windows, do not
call GetEnvironmentVariable. QUtil::get_env will always return
false. This option is not available through configure. This was
added to support a specific user's requirements to avoid calling
GetEnvironmentVariable from the Windows API. Nothing in qpdf outside
the test coverage system in qtest relies on QUtil::get_env.
Change object type Keyword to Operator, and place the order of the
object types in object_type_e in the same order as they are mentioned
in the PDF specification.
Note that this change only breaks backward compatibility with code
that has not yet been released.
