2019-06-22QPDFWriter: clean up overloaded functionsJay Berkenbilt
In a small number of cases, it makes sense to replace an overloaded function with a function that takes a default argument. We can do this now because we've already broken binary compatibility since the last release.
2019-06-22Convert remaining public classes to use Members patternJay Berkenbilt
Have classes contain only a single private member of type PointerHolder<Members>. This makes it safe to change the structure of the Members class without breaking binary compatibility. Many of the classes already follow this pattern quite successfully. This brings in the rest of the class that are part of the public API.
2019-06-22Build with -fvisibility=hidden when supportedJay Berkenbilt
2019-06-22Remove broken QPDFTokenizer::expectInlineImageJay Berkenbilt

2019-06-21Fix sign and conversion warnings (major)Jay Berkenbilt
This makes all integer type conversions that have potential data loss explicit with calls that do range checks and raise an exception. After this commit, qpdf builds with no warnings when -Wsign-conversion -Wconversion is used with gcc or clang or when -W3 -Wd4800 is used with MSVC. This significantly reduces the likelihood of potential crashes from bogus integer values. There are some parts of the code that take int when they should take size_t or an offset. Such places would make qpdf not support files with more than 2^31 of something that usually wouldn't be so large. In the event that such a file shows up and is valid, at least qpdf would raise an error in the right spot so the issue could be legitimately addressed rather than failing in some weird way because of a silent overflow condition.
2019-06-21Pl_Flate: constructor's out_bufsize is now unsigned intJay Berkenbilt
This is the type we need for the underlying zlib implementation.
2019-06-21Change QPDFObjectHandle::pipeStreamData's encode_flags typeJay Berkenbilt
Change from unsigned long to int since we pass enumerated type values to this field.
2019-06-21Add new integer accessors to QPDFObjectHandleJay Berkenbilt
2019-06-21QUtil: add unsigned int/string functionsJay Berkenbilt
2019-06-21New safe type converters in QIntCJay Berkenbilt

2019-03-11Fix C++ exception handling when -fvisibility=hidden (#302)jbarlow83
Fix C++ exception handling when -fvisibility=hidden Ensure that QPDFExc and QPDFSystemError are marked visible, so that their typeinfo will not be suppressed when -fvisibility=hidden. Details: https://gcc.gnu.org/wiki/Visibility

2019-02-01Make inline image token exactly contain the image dataJay Berkenbilt
Do not include the trailing EI, and handle cases where EI is not preceded by a delimiter. Such cases have been seen in the wild.
2019-01-31Externalize inline images (fixes #278)Jay Berkenbilt
2019-01-31Exclude space after ID in image dataJay Berkenbilt
2019-01-31Improve locating inline image's EIJay Berkenbilt
We've actually seen a PDF file in the wild that contained EI surrounded by delimiters inside the image data, which confused qpdf's naive code. This significantly improves EI detection.
2019-01-31Refactor QPDFTokenizer's inline image handlingJay Berkenbilt
Add a version of expectInlineImage that takes an input source and searches for EI. This is in preparation for improving the way EI is found. This commit just refactors the code without changing the functionality and adds tests to make sure the old and new code behave identically.
2019-01-30Clean up some private functionsJay Berkenbilt
2019-01-29Clarify documentation for copyForeignObject regarding pagesJay Berkenbilt
Make explicit that copyForeignObject can be used on page objects and will copy them properly but not update the pages tree.
2019-01-29Resolve duplicated page objects (fixes #268)Jay Berkenbilt
When linearizing a file or getting the list of all pages in a file, detect if the pages tree contains a duplicated page object and, if so, shallow copy it. This makes it possible to have a one to one mapping of page positions to page objects.
2019-01-27Convert pages to form XObjectsJay Berkenbilt
Support conversion of pages to form XObjects and placement of form XObjects on pages.
2019-01-27Add QPDFObjectHandle::getUniqueResourceNameJay Berkenbilt
2019-01-26Handle inheritable page attributesJay Berkenbilt
Add getAttribute for handling inheritable page attributes, and fix getPageImages and annotation flattening code to use it.
2019-01-19Add documentation for features since 8.3.0Jay Berkenbilt
2019-01-19mingw workaround for QPDFExc destructorJay Berkenbilt
mingw doesn't like it when you don't inline empty virtual destructors.
2019-01-17Add QUtil::possible_repaired_encodingsJay Berkenbilt
2019-01-17Modernize encryption API for more granularityJay Berkenbilt
Setting encryption permissions for R >= 3 set permission bits in groups corresponding to menu options in Acrobat 5. The new API allows the bits to be set individually.
2019-01-17Add status-reporting transcoders to QUtilJay Berkenbilt
2019-01-17QUtil::analyze_encodingJay Berkenbilt
2019-01-17Move remaining existing transcoding to QUtilJay Berkenbilt

2019-01-11Fix version number in commentJay Berkenbilt
2019-01-11Add QPDF::setImmediateCopyFromJay Berkenbilt
2019-01-07Update copyrights for 2019Jay Berkenbilt
2019-01-07Mostly don't require original QPDF for copyForeignObject (fixes #219)Jay Berkenbilt
The original QPDF is only required now when the source QPDFObjectHandle is a stream that gets its stream data from a QPDFObjectHandle::StreamDataProvider.
2019-01-07Make a static version of QPDF::pipeStreamDataJay Berkenbilt
This is in preparation of being able to pipe a stream's data without keeping a copy of its containing qpdf object.
2019-01-07Create an application-scope unique ID for each QPDF objectJay Berkenbilt
Use this instead of QPDF* as a map key for object_copiers.
2019-01-06Move encryption parameters into a classJay Berkenbilt
2019-01-06Honor other base encodings when generating appearancesJay Berkenbilt
