2019-01-04Add QUtil::utf8_to_asciiJay Berkenbilt
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 simple JSON serializerJay Berkenbilt
2018-08-14New exception class QPDFSystemError (fixes #221)Jay Berkenbilt
2018-08-13Catch exceptions as const references (fixes #236)Jay Berkenbilt
This fix allows qpdf to compile/test cleanly with gcc 8.
2018-08-05ClosedFileInputSource: 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.
2018-06-23Fix typoJay Berkenbilt
2018-06-22Windows test workaroundJay Berkenbilt
2018-06-22Add ClosedFileInputSourceJay Berkenbilt
ClosedFileInputSource is an input source that keeps the file closed when not reading it.
2018-06-21QUtil::toUTF16Jay Berkenbilt
2018-06-21Label qutil test outputJay Berkenbilt
2018-05-05buffer test: fix memory leak in test codeJay Berkenbilt
Forgot to delete a buffer in the test driver. There was no memory leak or memory error in any installed code.
2018-03-06Pl_Buffer starts in a ready stateJay Berkenbilt
2018-02-04Fix link order (fixes #176)Jay Berkenbilt
Specify qpdf libraries before external ones. Specify LDFLAGS before libraries. This should eliminate remaining cases of qpdf builds favoring previously installed versions.
2018-01-14Add QUtil::hex_decodeJay Berkenbilt
2018-01-14Use correct link directory order (fixes #158)Jay Berkenbilt
Make sure to link from the source tree before linking from the system. In many environments, this is necessary to allow a newly built qpdf to link properly instead of trying to link or resolve libraries from an older installed version.
2018-01-14Add Pl_TIFFPredictorJay Berkenbilt
2018-01-14Add signed support to BitStream and BitWriterJay Berkenbilt
2018-01-14Rename png_filter -> predictorsJay Berkenbilt
2017-12-26Add tests for new PNG filtersJay Berkenbilt
2017-12-25PNG filter test imagesJay Berkenbilt
2017-12-25Correct errors in PNG filters and make use from libraryJay Berkenbilt
2017-09-08Pl_DCT: Use custom source and destination managers (fixes #153)Jay Berkenbilt
Avoid calling jpeg_mem_src and jpeg_mem_dest. The custom destination manager writes to the pipeline in smaller chunks to avoid having the whole image in memory at once. The source manager works directly with the Buffer object. Using customer managers avoids use of memory source and destination managers, which are not present in older versions of libjpeg still in use by some Linux distributions.
2017-08-29Replace all atoi calls with QUtil::string_to_intJay Berkenbilt
The latter catches underflow/overflow.
2017-08-29Detect integer overflow/underflowJay Berkenbilt
2017-08-22Fix compiler warnings for clang/mac OS XJay Berkenbilt
2017-08-21Implement Pl_DCT pipelineJay Berkenbilt
Additional testing is added in later commits to be supported by additional changes in the library.
2017-08-19Implement Pl_RunLength pipelineJay Berkenbilt
2017-08-11Remove PCREJay Berkenbilt
2017-08-11Implement findFirst and findLast in InputSourceJay Berkenbilt
Preparing to refactor some pattern searching code to use these instead of their own memchr loops. This should simplify the code that replaces PCRE.
2017-07-30Allow reading command-line args from files (fixes #16)Jay Berkenbilt
2017-07-30Detect input file = output file (fixes #29)Jay Berkenbilt
2016-01-24Use RM_WS_ONLY_LINES in testThorsten Schöning
Some compilers output extra newlines in some cases.
2016-01-24Include stdlib.h to provide exitThorsten Schöning
2015-10-31Implement deterministic IDJay Berkenbilt
For non-encrypted files, determinstic ID generation uses file contents instead of timestamp and file name. At a small runtime cost, this enables generation of the same /ID if the same inputs are converted in the same way multiple times.
2013-12-16Remove needless #ifdef _WIN32 from getWhoamiJay Berkenbilt
2013-12-16Increase random data provider supportJay Berkenbilt
Add a method to get the current random data provider, and document and test the method for resetting it.
2013-12-14Allow OS-provided secure random to be disabledJay Berkenbilt
2013-12-14Refactor random data generationJay Berkenbilt
Add new RandomDataProvider object and implement existing random number generation in terms of that. This enables end users to supply their own random data providers.
2013-07-07Fix errors reported by CoverityJay Berkenbilt
Thanks to Jiri Popelka from Red Hat for sending the output of a Coverity run over qpdf.
2013-03-05Call QUtil::safe_fopen in place of fopenJay Berkenbilt
fopen was previuosly called wrapped by QUtil::fopen_wrapper, but QUtil::safe_fopen does this itself, which is less cumbersome.
2013-03-05Remove all calls to sprintfJay Berkenbilt
2013-03-05Use portable versions of some UNIX-specific callsJay Berkenbilt
Remove needless calls to open, close, and fileno; call remove instead of unlink.
2013-03-05Mark secure CRT warnings with commentJay Berkenbilt
Put a specific comment marker next to every piece of code that MSVC gives warning 4996 for. This warning is generated for calls to functions that Microsoft considers insecure or deprecated. This change is in preparation for fixing all these cases even though none of them are actually incorrect or insecure as used in qpdf. The comment marker makes them easier to find so they can be fixed in subsequent commits.
2013-03-04Rewrite QUtil::int_to_string and QUtil::double_to_stringJay Berkenbilt
Make them safer by avoiding any internal limits and replacing sprintf with std::ostringstream.
2013-03-04Fix unused local variable warningsJay Berkenbilt
2013-03-04Remove all old-style casts from C++ codeJay Berkenbilt
