2021-01-25name/number trees: insertAfterJay Berkenbilt
2021-01-25name/number trees: newEmpty, increment/decrement end()Jay Berkenbilt
2021-01-25Implement repair and insert for name/number treesJay Berkenbilt
2021-01-24QPDFObjectHandle::newUnicodeString to uses UTF-16 only when neededJay Berkenbilt
Use the first of ASCII, PDFDocEncoding, or UTF-16 that is capable of encoding the string.
2021-01-24Use new QPDF{Name,Number}TreeObjectHelper APIJay Berkenbilt
2021-01-24Add new constructors for name/number tree helpersJay Berkenbilt
Add constructors that take a QPDF object so we can issue warnings and create new indirect objects.
2021-01-24Use QPDFNameTreeObjectHelper's iterator directlyJay Berkenbilt
2021-01-24Add iterators to name/number tree helpersJay Berkenbilt
2021-01-24Reimplement name and number tree object helpersJay Berkenbilt
Create a computationally and memory efficient implementation of name and number trees that does binary searches as intended by the data structure rather than loading into a map, which can use a great deal of memory and can be very slow.
2021-01-17Add warn() to QPDF's public APIJay Berkenbilt
2021-01-11Treat /EmbeddedFiles as a proper name treeJay Berkenbilt
If we ever had an encrypted file with different filters for attachments and either the /EmbeddedFiles name tree was deep or some of the file specs didn't have /Type, we would have overlooked those as attachment streams. The code now properly handles /EmbeddedFiles as a name tree.
2021-01-06Warn rather than segv on access after closing input source (fixes #495)Jay Berkenbilt
2021-01-04Prepare version 10.1.0release-qpdf-10.1.0Jay Berkenbilt
2021-01-04Spell checkJay Berkenbilt
2021-01-04Fix some pipelines to be safe if downstream write fails (fuzz issue 28262)Jay Berkenbilt
2021-01-03Fix outdated commentJay Berkenbilt
2021-01-02Make more QPDFPageObjectHelper methods work with form XObjectJay Berkenbilt
2021-01-02Externalize inline images now includes form XObjectsJay Berkenbilt
2021-01-02Bug fix: avoid extraneous pipeline finish calls with multiple contentsJay Berkenbilt
Avoid calling finish() multiple times on the pipeline passed to pipeContentStreams. This commit also fixes a bug in which qpdf was not exiting with the proper exit status if warnings found while splitting pages; this was exposed by a test case that changed.
2021-01-02Add several methods for working with form XObjects (fixes #436)Jay Berkenbilt
Make some more methods in QPDFPageObjectHelper work with form XObjects, provide forEach methods to walk through nested form XObjects, possibly recursively. This should make it easier to work with form XObjects from user code.
2021-01-02QPDFPageObjectHelper: filterPageContents -> filterContents + form XObjectJay Berkenbilt
2021-01-02QPDFPageObjectHelper: getPageImages -> getImagesJay Berkenbilt
2021-01-02QPDFPageObjectHelper::getPageImages: support form XObjectsJay Berkenbilt
2021-01-01Add QPDFObjectHandle::isFormXObjectJay Berkenbilt
2020-12-30Add QPDFPageObjectHelper::flattenRotation and --flatten-rotationJay Berkenbilt
2020-12-28Add QPDFObjectHandle::setFilterOnWriteJay Berkenbilt
2020-12-28Add ostream << for QPDFObjGenJay Berkenbilt
2020-12-28Let optimize filter stream parameters instead of making them directJay Berkenbilt
Also removes preclusion of stream references in stream parameters of filterable streams and reduces write times by about 8% by eliminating an extra traversal of the objects.
2020-12-28Restructure optimize to allow skipping parameters of filtered streamsJay Berkenbilt
2020-12-28Refactor: separate code that determines whether to filter a streamJay Berkenbilt
2020-12-28Implement user-provided stream filtersJay Berkenbilt
Refactor QPDF_Stream to use stream filter classes to handle supported stream filters as well.
2020-12-26Add QPDFObjectHandle::makeDirect(bool allow_streams)Jay Berkenbilt
2020-12-20Provide qpdf write progress reporting from C API (fixes #487)Jay Berkenbilt
2020-11-29Add QPDFObjectHandle manipulation to C APIJay Berkenbilt
2020-11-21Prepare 10.0.4 releaserelease-qpdf-10.0.4Jay Berkenbilt
2020-11-11Treat direct page as runtime rather than logic error (fuzz issue 27393)Jay Berkenbilt
2020-11-04Ignore unused field in xref entry, avoiding range error (fixes #482)Jay Berkenbilt
2020-10-31Prepare 10.0.3 releaserelease-qpdf-10.0.3Jay Berkenbilt
2020-10-31Fix stack overflow on direct root (fuzz issue 26761)Jay Berkenbilt
2020-10-31Add comments explaining the foreign object copying codeJay Berkenbilt
These are the comments I would have liked to have been able to read while fixing #449 and #478.
2020-10-31Fix foreign stream copying bug (fixes #478)Jay Berkenbilt
This reverts an incorrect fix to #449 and codes it properly. The real problem was that we were looking at the local dictionaries rather than the foreign dictionaries when saving the foreign stream data. In the case of direct objects, these happened to be the same, but in the case of indirect objects, the object references could be pointing anywhere since object numbers don't match up between the old and new files.
2020-10-27Prepare 10.0.2 releaserelease-qpdf-10.0.2Jay Berkenbilt
2020-10-27Improve efficiency of number to string conversionJay Berkenbilt
2020-10-27Revert removal of unreadCh change for performanceJay Berkenbilt
Turns out unreadCh is much more efficient than seek(-1, SEEK_CUR). Update comments and code to reflect this.
2020-10-23Avoid merging adjacent tokens when concatenating contents (fixes #444)Jay Berkenbilt
2020-10-22Avoid leak by resolving object streams more than once (fuzz issue 23642)Jay Berkenbilt
2020-10-22Minor code cleanupJay Berkenbilt
* Return rather than exiting from realmain in qpdf.cc * Remove extraneous blank line * Don't assign temporary to const reference
2020-10-22Handle jpeg library fuzz false positivesJay Berkenbilt
The jpeg library has some assembly code that is missed by the compiler instrumentation used by memory sanitization. There is a runtime environment variable that is used to work around this issue.
