2021-01-02	Make more QPDFPageObjectHelper methods work with form XObject	Jay Berkenbilt

2019-08-20	Handle invalid name tokens symmetrically for PDF < 1.2 (fixes #332)	Jay Berkenbilt

2019-06-22	Remove broken QPDFTokenizer::expectInlineImage	Jay Berkenbilt

2019-06-21	Fix sign and conversion warnings (major)	Jay Berkenbilt
	This makes all integer type conversions that have potential data loss explicit with calls that do range checks and raise an exception. After this commit, qpdf builds with no warnings when -Wsign-conversion -Wconversion is used with gcc or clang or when -W3 -Wd4800 is used with MSVC. This significantly reduces the likelihood of potential crashes from bogus integer values. There are some parts of the code that take int when they should take size_t or an offset. Such places would make qpdf not support files with more than 2^31 of something that usually wouldn't be so large. In the event that such a file shows up and is valid, at least qpdf would raise an error in the right spot so the issue could be legitimately addressed rather than failing in some weird way because of a silent overflow condition.
2019-01-31	Exclude space after ID in image data	Jay Berkenbilt

2019-01-31	Refactor QPDFTokenizer's inline image handling	Jay Berkenbilt
	Add a version of expectInlineImage that takes an input source and searches for EI. This is in preparation for improving the way EI is found. This commit just refactors the code without changing the functionality and adds tests to make sure the old and new code behave identically.
2018-06-21	Convert command-line and test suite to use page helper classes	Jay Berkenbilt
	This provides better test coverage and more useful code for people to read and copy.
2018-02-19	Use pipePageContents in tokenizer test	Jay Berkenbilt

2018-02-19	Inline image token type	Jay Berkenbilt

2018-02-19	Lexer enhancements: EOF, comment, space	Jay Berkenbilt
	Significant enhancements to the lexer to improve EOF handling and to support comments and spaces as tokens. Various other minor issues were fixed as well.
2018-02-19	Create isolated tokenizer tests	Jay Berkenbilt
	This tokenizes outer parts of the file, page content streams, and object streams. It is for exercising the tokenizer in isolation and is being introduced before reworking the lexical layer of qpdf.
