Move ArgParser from qpdf.cc into QPDFJob.cc. It still works with
millions of public member variables, but now qpdf.cc is minimal and
just calls stable library functions.
|
|
|
|
Convert remaining static functions that take QPDFJob& as a parameter
to member functions. Utility functions that don't take QPDFJob& remain
static functions and can probably just stay that way since the keep
extra complexity out of QPDFJob.hh.
|
|
|
|
Remove remaining temporary duplication of hard-coded values and direct
access to std::cout, std::cerr, and whoami in favor of parameters in
QPDFJob. This moves a few more static methods into QPDFJob member
functions.
|
|
Remove all calls to exit() from QPDFJob. Handle code that runs in
verbose mode to enable it to make use of output streams and message
prefix (whoami) from QPDFJob. This removes temporarily duplicated exit
code logic and most access to whoami/std::cout outside of QPDFJob
proper.
|
|
Move most of the methods called from qpdf.cc after argument parsing
into QPDFJob. In this increment, enough QPDFJob API has been added to
handle the branch of QPDFJob::run() that creates output with an
appropriate division between qpdf.cc and QPDFJob.
There are temporary bits of code to enable everything to compile and
pass the test suite, including some duplication and hard-coded values.

Ensure isOrHasName returns true if object is an array and the name is
present anywhere in the array.
|
|
Use QPDFObjectHandle::isNameAndEquals, isDictionaryOfType and
isStreamOfType.
|
|
Accept empty string as type parameter in
QPDFObjectHandle::isDictionaryOfType and isStreamOfType
to allow for dictionaries with optional type.

Commit by ejb@ql.org using m-holger as author so git annotate gives
proper credit for changes.
|
|
Add methods isNameAndEquals, isDictionaryOfType, isStreamOfType

They have to be ot_* rather than qpdf_ot_* for compatibility.
* Different enumerated types are not assignment-compatible in C++, at
least with strict compiler settings
* While you can do `constexpr ot_xyz = ::qpdf_ot_xyz` in QPDFObject.hh to
make QPDFObject::ot_xyz work, QPDFObject::object_type_e::ot_xyz will
only work if the enumerated type names are the same.

* Make it a runtime error, not a logic error
* Include additional information
* Capture it properly in checkLinearization
|
|
|
|
* Handle error conditions that occur when using the object handle
interfaces. In the past, some exceptions were not correctly
converted to errors or warnings.
* Add more detailed information to qpdf-c.h
* Make it possible to work more explicitly with uninitialized objects

It was exercised in the pdf-linearize example but not in qpdf-ctest.

Return new qpdf_oh from qpdf_oh_wrap_in_array when input is already an array.
Update some doc comments in qpdf-c.h.

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.

When making resources indirect in from_dr, the code was using the
wrong owning QPDF, forgetting that from_dr had already been copied
using CopyForeignObject.
|
|
When adding a QPDFObjectHandle to an array or dictionary, if possible,
check if the new object belongs to the same QPDF. This makes it much
easier to find incorrect code than waiting for the situation to be
detected when the file is written.

This was originally not public because I wanted to get rid fo the
pages cache, but I recently realized there were deep reasons not to do
that, and the author of pikepdf wanted this, so I decided to make it
public.

The /Subtype entry that specifies the mime type of an embedded file is
inside the embedded file stream dictionary directly, not it in the
parameter dictionary.
