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
2019-06-18Remove qpdf_read_memory_fuzzerJay Berkenbilt
2019-06-15Run tests with sanitizers in CIJay Berkenbilt
2019-06-15As a test suite, run stand-alone fuzzer on seed corpusJay Berkenbilt
Temporarily skip fuzz tests on Windows. There are Windows-specific failures to address later.
2019-06-15Give up reading objects with too many consecutive errorsJay Berkenbilt
2019-06-13oss-fuzz initial integrationJay Berkenbilt
2019-06-09Handle empty DecodeParams array for (fixes #331)Jay Berkenbilt
On read, ignore /DecodeParms when empty list; on write, delete it. Some files have been found that include an empty list for /DecodeParms, but this is not technically compliant with the spec, and the only sensible interpretation is to treat it as if there are no decode parameters.
2019-05-18Prepare 8.4.2 releaseJay Berkenbilt
2019-05-16Fix Windows memory error (fixes #330)Jay Berkenbilt
2019-04-28Prepare 8.4.1 releaserelease-qpdf-8.4.1Jay Berkenbilt
2019-04-21Compare versions between CLI and libraryJay Berkenbilt
2019-04-21Add --remove-page-labels option (fixes #317)Jay Berkenbilt
2019-04-21Add --keep-files-open-threshold (fixes #288)Jay Berkenbilt
2019-04-21Support Unicode in filenames (fixes #298)Jay Berkenbilt
2019-04-21Tighten isPageObject (fixes #310)Jay Berkenbilt
2019-04-21Revert preservations of outlines with --split-pagesJay Berkenbilt
The preservation of outlines didn't provide very useful behavior anyway as it copied all outlines but most didn't work. This implementation also caused a very significant performance hit and so is being reverted until a proper solution can be coded. The eventual solution will not be compatible with the reverted solution anyway, so it's best not to leave this in.
2019-03-11Fix json serialization for {x | -1 < x < 1} (fixes #308)Jay Berkenbilt
JSON serialization was preserving the value as presented, but JSON doesn't accept decimal values without a 0 before the decimal point.
2019-02-02Prepare 8.4.0 releaseJay Berkenbilt
2019-02-01Don't optimize non-8-bit imagesJay Berkenbilt
Also add test cases for additional coverage on image optimization.
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
2019-01-31Remove acroread from testsJay Berkenbilt
This hasn't worked or been exercised in years since Adobe stopped releasing a Linux version of reader.
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.
2019-01-31Inline image token value ends with EI, not delimiterJay Berkenbilt
The inline image token erroneously included the delimiter that followed EI. The ObjectHandle created from it was correct.
2019-01-29Handle direct page objects (fixes #164)Jay Berkenbilt
2019-01-29Fix logic for when to compress object and xref streams (fixes #271)Jay Berkenbilt
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.
2019-01-27Add --overlay and --underlay to qpdf CLI (fixes #207)Jay Berkenbilt
2019-01-27Example of form XObject, page overlayJay Berkenbilt
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.
2019-01-21Handle fallback font size in text appearancesJay Berkenbilt
If we end up using our fallback font size when generating appearances for text fields, reflect that in the Tf operator used in the appearance stream.
2019-01-21Fix omissions in text appearance generationJay Berkenbilt
When generating appearance streams for variable text annotations, properly handle the cases of there being no appearance dictionary, no appearance stream, or an appearance stream with no BMC..EMC marker.
2019-01-21When flattening, remove annotations with no appearance streamJay Berkenbilt
With the exception of form field annotations when /NeedAppearances is true, remove annotations that don't have appearance streams when flattening. There is no reason to keep these when flattening since they are invisible. This may include unchecked checkboxes, unshown popup windows, etc.
2019-01-19Implement password recovery suppression and password mode (fixes #215)Jay Berkenbilt
Allow fine control over how passwords are encoded for writing, and allow password for reading to be given as a hexademical encoded string. Allow suppression of password recovery as a means to ensure that the password you specify is actually the right one.
2019-01-19Try passwords with different string encodingsJay Berkenbilt
2019-01-17Add QUtil::possible_repaired_encodingsJay Berkenbilt
2019-01-17Update CLI and manual for new encryption granularity (fixes #214)Jay 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
2019-01-17Add tests for shared font/xobjectJay Berkenbilt
The tests are in a separate commit so the bug-fix commit can be taken as a patch for older versions.
2019-01-12Allow adding the same page more than once in --pages (fixes #272)Jay Berkenbilt
2019-01-12Interpret . in --pages as a shortcut for the primary fileJay Berkenbilt
2019-01-11Add configure option AVOID_WINDOWS_HANDLEJay Berkenbilt
If set, we avoid using Windows I/O HANDLE, which is disallowed in some versions of the Windows SDK, such as for Windows phones. QUtil::same_file will always return false in this case. Only applies to Windows builds.
2019-01-11Add QPDF::setImmediateCopyFromJay Berkenbilt
