2022-01-27Remove some if statements and simplify some boolean expressionsm-holger Use QPDFObjectHandle::isNameAndEquals, isDictionaryOfType and isStreamOfType. 2021-11-03Make QPDF::findPage public (fixes #516)Jay Berkenbilt 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. 2021-04-05QPDF::addPage*: handle duplicate pages more robustlyJay Berkenbilt 2021-03-22Remove some assertions that are not necessarily true (fixes #514)Jay Berkenbilt Operations that add the same object to multiple places in the pages tree are throwing exceptions and then later causing assertion failures. The assert calls shouldn't be there. 2020-02-22Handle root /Pages pointing to other than page tree root (fixes #398)Jay Berkenbilt 2019-08-19Attempt to repair /Type key in pages nodes (fixes #349)Jay Berkenbilt 2019-06-25Convert some cases of logic_error to runtime_errorJay Berkenbilt There were a few cases that could be caused by invalid input rather than bugs in the code which were throwing logic_error instead of runtime_error. 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. 2019-01-30Clean up some private functionsJay Berkenbilt 2019-01-29Handle direct page objects (fixes #164)Jay 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. 2018-03-06Properly handle pages with no contents (fixes #194)Jay Berkenbilt Remove calls to assertPageObject(). All cases in the library that called assertPageObject() work fine if you don't call assertPageObject() because nothing assumes anything that was being checked by that call. Removing the calls enables more files to be successfully processed. 2017-08-22Push QPDF member variables into a nested classJay Berkenbilt Pushing member variables into a nested class enables addition of new member variables without breaking binary compatibility. 2015-02-22Detect loops in /Pages structureJay Berkenbilt Pushing inherited objects to pages and getting all pages were both prone to stack overflow infinite loops if there were loops in the Pages dictionary. There is a general weakness in the code in that any part of the code that traverses the Pages structure would be prone to this and would have to implement its own loop detection. A more robust fix may provide some general method for handling the Pages structure, but it's probably not worth doing. Note: addition of *Internal2 private functions was done rather than changing signatures of existing methods to avoid breaking compatibility. 2014-12-29Handle page tree node with no /TypeJay Berkenbilt Original reported here: https://bugs.launchpad.net/ubuntu/+source/qpdf/+bug/1397413 The PDF specification says that the /Type key for nodes in the pages dictionary (both /Page and /Pages) is required, but some PDF files omit them. Use the presence of other keys to determine the type of pages tree node this is if the type key is not found. 2013-10-18Security: replace operator[] with atJay Berkenbilt For std::string and std::vector, replace operator[] with at. This was done using an automated process. See README.hardening for details. 2013-10-10Replace some assertions with std::logic_errorJay Berkenbilt Ideally, the library should never call assert outside of test code, but it does in several places. For some cases where the assertion might conceivably fail because of a problem with the input data, replace assertions with exceptions so that they can be trapped by the calling application. This commit surely misses some cases and replaced some cases unnecessarily, but it should still be an improvement. 2013-06-14Use QPDFObjectHandle::getObjGen() where appropriateJay Berkenbilt In internal code and examples, replace calls to getObjectID() and getGeneration() with calls to getObjGen() where possible. 2013-06-14Promote QPDF::ObjGen to top-level object QPDFObjGenJay Berkenbilt 2013-03-04Remove all old-style casts from C++ codeJay Berkenbilt 2012-07-29Fix spelling errorsJay Berkenbilt 2012-07-11Support copying objects from another QPDF objectJay Berkenbilt This includes QPDF::copyForeignObject and supporting foreign objects as arguments to addPage*. 2012-07-07Build this->all_pages while traversing with pushInheritedAttributesToPageTobias Hoffmann 2012-07-05Limited inheritance to the attributes explicitly listed in the PDF specTobias Hoffmann Previous versions of qpdf incorrectly passed arbitrary objects from /Pages objects down to individual pages in direct contradition with the PDF specification. These are now left in /Pages. When intermediate /Pages nodes are being discarded as when the /Pages tree is being flattened, a warning is issued when unknown keys are encountered. 2012-07-04Added public method QPDF::pushInheritedAttributesToPageTobias Hoffmann Refactored optimizePagesTree to pushInheritedAttributesToPage and made public 2012-06-24Fixed missing throwTobias Hoffmann 2012-06-22Add QPDF::emptyPDF() and pdf_from_scratch test codeJay Berkenbilt 2012-06-21Use getRoot() instead of looking it up in the trailerJay Berkenbilt 2012-06-21Add testing for page APIsJay Berkenbilt 2012-06-21Implement page manipulation APIsJay Berkenbilt 2012-06-21Split page handling APIs into a separate source fileJay Berkenbilt
