2019-01-04Don't call assert while checking linearization data (fixes #209, #231)Jay Berkenbilt
Instead of calling assert for problems found during checking linearization data, throw an exception which is later caught and issued as an error. Ideally we would handle errors more robustly, but this is still a significant improvement.
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.
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.
2013-06-15Handle /Outlines dictionary being a direct objectJay Berkenbilt
Even though this case is not valid according to the spec, it has been seen, and caused an internal error.
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.

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
2012-06-22Add QPDF::emptyPDF() and pdf_from_scratch test codeJay Berkenbilt
2012-06-21Refactor optimizePagesTreeJay Berkenbilt
Split optimizePagesTree into a simpler top-level routine and a recursive internal routine.
