2019-01-07Mostly don't require original QPDF for copyForeignObject (fixes #219)Jay Berkenbilt
The original QPDF is only required now when the source QPDFObjectHandle is a stream that gets its stream data from a QPDFObjectHandle::StreamDataProvider.
2018-12-22Add QPDFObjectHandle::getJSON()Jay 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.
2018-02-19Simplify TokenFilter interfaceJay Berkenbilt
Expose Pl_QPDFTokenizer, and have it do more of the work of managing the token filter's pipeline.
2018-02-19Detect and report bad tokens in content normalizationJay 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.
2018-01-14Support TIFF Predictor (fixes #171)Jay Berkenbilt
2018-01-14Use better error for getStreamData failureJay Berkenbilt
If the stream isn't filterable but we call getStreamData, throw a regular exception instead of a logic error so that normal error handling and reporting mechanisms will be used.
2017-12-25Correct errors in PNG filters and make use from libraryJay Berkenbilt
2017-09-12Improve message for stream decoding errorJay Berkenbilt
Tweak the message so that we inform the user that we are mitigating data loss.
2017-08-29Clean up circular references in QPDF_StreamJay Berkenbilt
2017-08-21Enable finer grained control of stream decodingJay Berkenbilt
This commit adds several API methods that enable control over which types of filters QPDF will attempt to decode. It also adds support for /RunLengthDecode and /DCTDecode filters for both encoding and decoding.
2017-07-28Add precheck streams capabilityJay Berkenbilt
When requested, QPDFWriter will do more aggress prechecking of streams to make sure it can actually succeed in decoding them before attempting to do so. This will allow preservation of raw data even when the raw data is corrupted relative to the specified filters.
2017-07-28Convert stream filtering errors to warningsJay Berkenbilt
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.
2013-07-08Ignore broken DecodeParms for stream with no filtersJay Berkenbilt
2013-03-04Remove all old-style casts from C++ codeJay Berkenbilt
2013-01-22Add getTypeCode() and getTypeName()Jay Berkenbilt
Add virtual methods to QPDFObject, wrappers to QPDFObjectHandle, and implementations to all the QPDF_Object types.
2012-12-31Support files with only attachments encryptedJay Berkenbilt
Test cases added in a future commit since they depend on /R=6 support.
2012-07-21Implement QPDFObjectHandle::parseJay Berkenbilt
Move object parsing code from QPDF to QPDFObjectHandle and parameterize the parts of it that are specific to a QPDF object. Provide a version that can't handle indirect objects and that can be called on an arbitrary string. A side effect of this change is that the offset used when reporting invalid stream length has changed, but since the new value seems like a better value than the old one, the test suite has been updated rather than making the code backward compatible. This only effects the offset reported for invalid streams that lack /Length or have an invalid /Length key. Updated some test code and exmaples to use QPDFObjectHandle::parse. Supporting changes include adding a BufferInputSource constructor that takes a string.
2012-07-07Don't require stream data provider to know length in advanceJay Berkenbilt
Breaking API change: length parameter has disappeared from the StreamDataProvider version of QPDFObjectHandle::replaceStreamData since it is no longer necessary to compute it in advance. This breaking change is justified by the fact that removing the length parameter provides the caller an opportunity to simplify the calling code.
2012-06-22Use qpdf_offset_t in place of off_t in public APIs.Jay Berkenbilt
off_t is used internally only when needed to talk to standard libraries. This requires that the "long long" type be supported by the compiler.
2012-06-20ABI change: fix use of off_t, size_t, and integer typesJay Berkenbilt
Significantly improve the code's use of off_t for file offsets, size_t for memory sizes, and integer types in cases where there has to be compatibility with external interfaces. Rework sections of the code that would have prevented qpdf from working on files larger than 2 (or maybe 4) GB in size.
