2019-01-06Honor other base encodings when generating appearancesJay Berkenbilt
2019-01-06Add WinAnsi and MacRoman encodingJay Berkenbilt
2019-01-06Refactor QUtil::utf8_to_asciiJay Berkenbilt
2019-01-06Move utf8_to_utf16 into QUtilJay Berkenbilt
2019-01-06Refactor string transcoding in QPDF_StringJay Berkenbilt
2019-01-05Spell checkJay Berkenbilt
2019-01-04Add QPDFWriter::getFinalVersion (fixes #266)Jay Berkenbilt
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.
2019-01-04Fix dangling references (fixes #240)Jay Berkenbilt
On certain operations, such as iterating through all objects and adding new indirect objects, walk through the entire object structure and explicitly resolve any indirect references to non-existent objects. That prevents new objects from springing into existence and causing the previously dangling references to point to them.
2019-01-04Add basic appearance stream generationJay Berkenbilt
2019-01-04Add QUtil::utf8_to_asciiJay Berkenbilt
2019-01-04Add special case setV code for button fieldsJay Berkenbilt
2019-01-04Add form fields to json outputJay Berkenbilt
Also add some additional methods for detecting form field types to assist in the json creation and for later use.
2019-01-03Honor flags when flattening annotationsJay Berkenbilt
2019-01-03Minor fixesJay Berkenbilt
2019-01-03Fix seg fault on empty xref stream (fixes #263)Jay Berkenbilt
Thanks to @p-cher for supplying a patch.
2019-01-03Switch annotation flattening to use the form xobjectsJay Berkenbilt
Instead of directly putting the contents of the annotation appearance streams into the page's content stream, add commands to render the form xobjects directly. This is a more robust way to do it than the original solution as it works properly with patterns and avoids problems with resource name clashes between the pages and the form xobjects.
2019-01-01Annotation flattening including form fieldsJay Berkenbilt
Flatten annotations by integrating their appearance streams into the content stream of the containing page. In the case of form fields, only flatten if /NeedAppearance is false (or equivalently absent). If flattening form fields, also remove /AcroForm from the document catalog.
2019-01-01Add QPDFObjectHandle::mergeDictionary()Jay Berkenbilt
2019-01-01Add matrix and annotation appearance stream handlingJay Berkenbilt
Generate page content fragment for rendering appearance streams including all matrix calculation.
2019-01-01Add Matrix class under QPDFObjectHandleJay Berkenbilt
2019-01-01Transformation matrixJay Berkenbilt
2018-12-25JSON::serialize -> unparseJay Berkenbilt
Unparse is admittedly strange, but I'd rather be strange and consistent, and everything else in the qpdf library uses unparse to serialize. (If you're reading this, the convention of using "unparse" comes from the "clu" programming language.)
2018-12-22Move numrange code from qpdf.cc to QUtil.ccJay Berkenbilt
Also move tests to libtests.
2018-12-22Add document and object helpers for outlines (bookmarks)Jay Berkenbilt
2018-12-22Add QPDFObjectHandle::getJSON()Jay Berkenbilt
2018-12-22Add simple JSON serializerJay Berkenbilt
2018-12-22Add QPDFNameTreeObjectHelperJay Berkenbilt
2018-12-21Minor cleanupJay Berkenbilt
2018-12-18Add QPDFPageLabelDocumentHelperJay Berkenbilt
2018-12-18Add QPDFNumberTreeObjectHelperJay Berkenbilt
2018-12-18Add QPDFObjectHandle::wrapInArray()Jay Berkenbilt
Wrap an object in an array if it is not already an array.

2018-08-16Prepare 8.2.0 releaserelease-qpdf-8.2.0Jay Berkenbilt
2018-08-16Missing header for std::maxJay Berkenbilt
2018-08-14Fix error in QPDFSystemError.ccJay Berkenbilt
2018-08-14New exception class QPDFSystemError (fixes #221)Jay Berkenbilt
2018-08-13Fix fallback logic for encryption (fixes #229)Jay Berkenbilt
2018-08-13Fix one more identifier (fixes #236)Jay Berkenbilt
2018-08-13Catch exceptions as const references (fixes #236)Jay Berkenbilt
This fix allows qpdf to compile/test cleanly with gcc 8.
2018-08-12Pl_Buffer: reduce memory growth (fixes #228)Jay Berkenbilt
Rather than keeping a list of buffers for every write, accumulate bytes in a single buffer, doubling the size of the buffer when needed to accommodate new data. This is not the best possible implementation, but the change was implemented in this way to avoid changing the shape of Pl_Buffer and thus breaking backward compatibility.
2018-08-12Protect headers with compliant identifiers (fixes #233)Jay Berkenbilt
2018-08-12Fix memory access errorJay Berkenbilt
A previous fix introduced a potentially memory overrun under certain rare conditions. The test suite now once again passes with address sanitizer.
2018-08-12Remove some extraneous null pointer checks (fixes #234)Jay Berkenbilt
There were a few places in the code that were checking that a pointer wasn't null before deleting it, even though C++ has always allowed delete 0. Most of the code did not perform these checks.
2018-08-06Fix EOL handling inside strings (fixes #226)Jay Berkenbilt
CR, CRLF, and LF are all supposed to be treated as LF; only one EOL is to be ignored after backslash.
2018-08-05Return correct method for string encryption (fixes #227)Jay Berkenbilt
2018-08-05Fix infinite loop on small files with progress reporting (fixes #230)Jay Berkenbilt
Turns out you can keep adding zero to a number over and over again and it just doesn't get any bigger. Who would have known?
2018-08-05ClosedFileInputSource: add method to keep file openJay Berkenbilt
During periods of intensive operation on a specific file, this method can reduce the overhead of repeated open/close operations.
2018-06-23Prepare 8.1.0 releaserelease-qpdf-8.1.0Jay Berkenbilt
