2018-08-18Add --keep-files-open flag (fixes #237)Jay Berkenbilt
2018-08-16Prepare 8.2.0 releaserelease-qpdf-8.2.0Jay Berkenbilt
2018-08-16Spell checkJay Berkenbilt
2018-08-14Clarify static vs. import library on Windows (fixes #225)Jay Berkenbilt
2018-08-14New exception class QPDFSystemError (fixes #221)Jay Berkenbilt
2018-08-13Add --no-warn option to suppress warnings (fixes #232)Jay Berkenbilt
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.
2018-08-06Fix 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.
2018-08-05Fix 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?
2018-08-05Keep file open while adding its pages during merge (fixes #217)Jay Berkenbilt
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
2018-06-22With --verbose, give information on processing merge inputsJay Berkenbilt
2018-06-22Add progress reporting for QPDFWriter (fixes #200)Jay Berkenbilt
2018-06-22Add method to get count of objects in QPDFJay Berkenbilt
2018-06-22Use ClosedFileInputSource when merging files (fixes #154)Jay Berkenbilt
2018-06-22Add ClosedFileInputSourceJay Berkenbilt
ClosedFileInputSource is an input source that keeps the file closed when not reading it.
2018-06-22Don't prune resource dictionaries on errors or by requestJay Berkenbilt
If we are unable to filter a page's content streams, don't attempt to remove objects from the page's resource dictionary. Also provide a command line option to suppress resource removal in case we ever need this as a workaround for some bug or broken PDF files.
2018-06-22When splitting files, remove unreferenced objects (fixes #203)Jay Berkenbilt
2018-06-21Make page range optional in --rotate (fixes #211)Jay Berkenbilt
2018-06-21Add interactive form exampleJay Berkenbilt
2018-06-21Allow setting a form field's valueJay Berkenbilt
2018-06-21Better support for creating Unicode stringsJay Berkenbilt
2018-06-21Implement helper class for interactive formsJay Berkenbilt
2018-06-21Convert examples to use new page helper classesJay Berkenbilt
2018-06-21Add QPDFPageDocumentHelper and QPDFPageObjectHelperJay Berkenbilt
This is the beginning of higher-level API support using helper classes. The goal is to be able to add more helpers without continuing to pollute QPDF's and QPDFObjectHandle's public interfaces.
2018-06-21Add QPDFObjectHandle::Rectangle typeJay Berkenbilt
Provide a convenient way of accessing rectangles.
2018-05-12newline before endstream fix for object streams (fixes #205)Jay Berkenbilt
2018-04-15Limit depth of nesting in direct objects (fixes #202)Jay Berkenbilt
This fixes CVE-2018-9918.
2018-03-06Prepare 8.0.2 releaserelease-qpdf-8.0.2Jay Berkenbilt
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.
2018-03-05Treat loop in xref tables as damage (fixes #192)Jay Berkenbilt
Prior to this fix, if there was a loop detected in following /Prev pointers in xref streams/tables, it would cause qpdf to lose data. Note that this condition causes many PDF readers to hang or fail.
2018-03-04Prepare 8.0.1 releaserelease-qpdf-8.0.1Jay Berkenbilt
2018-03-04Support "r" in page ranges (fixes #155)Jay Berkenbilt
2018-03-03Ignore zlib data check errors (fixes #191)Jay Berkenbilt
2018-02-25Release 8.0.0release-qpdf-8.0.0Jay Berkenbilt
2018-02-19Properly handle strings with PDF Doc Encoding (fixes #179)Jay Berkenbilt
The QPDF_String::getUTF8Val() method was not treating strings that weren't explicitly Unicode as PDF Doc Encoded. This only affects characters in the range 0x80 through 0xa0.
2018-02-19Add C API for checking PDF filesJay Berkenbilt
2018-02-19More robust handling of type errorsJay Berkenbilt
Give objects descriptions and context so it is possible to issue warnings instead of fatal errors for attempts to access objects of the wrong type.
2018-02-19Replace "file position" with "offset" in error messagesJay Berkenbilt
Sometimes it's an offset in an object stream or a content stream, so file position is confusing in some cases.
2018-02-19Include omitted object description in error messageJay Berkenbilt
2018-02-19Include filename in object stream parse errorJay Berkenbilt
2018-02-19Add additional interface for filtering page contentsJay Berkenbilt
2018-02-19General comment in ChangeLogJay Berkenbilt
2018-02-19Detect and report bad tokens in content normalizationJay Berkenbilt
2018-02-19Filter tokens exampleJay Berkenbilt
2018-02-19Implement TokenFilter and refactor Pl_QPDFTokenizerJay Berkenbilt
Implement a TokenFilter class and refactor Pl_QPDFTokenizer to use a TokenFilter class called ContentNormalizer. Pl_QPDFTokenizer is now a general filter that passes data through a TokenFilter.
2018-02-19Add coalesce contents capabilityJay Berkenbilt
2018-02-19Bug fix: content normalizer should not add trailing newlineJay Berkenbilt
Adding a trailing newline in content normalization damages files whose contents are split across streams in the middle of tokens. Let QPDFWriter add the newline with the indicator to ignore the newline, which it already does. This changes the way some qdf files look.
