-
Wrap an object in an array if it is not already an array.
-
CR, CRLF, and LF are all supposed to be treated as LF; only one EOL is to be ignored after backslash.
-
A few public destructors were missing QPDF_DLL, which could cause some Windows applications to fail to link.
-
During periods of intensive operation on a specific file, this method can reduce the overhead of repeated open/close operations.
-
ClosedFileInputSource is an input source that keeps the file closed when not reading it.
-
It's not really a shallow copy. It just doesn't cross indirect object boundaries. The old implementation had a bug that would cause multiple shallow copies of the same object to share memory, which was not the intention.
-
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.
-
Provide a convenient way of accessing rectangles.
-
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.
-
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.
-
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.
-
As in other cases, this is to enable adding new member variables in the future without breaking ABI compatibility.
-
Expose Pl_QPDFTokenizer, and have it do more of the work of managing the token filter's pipeline.
-
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.
-
Remove a redundant method that was equal to another one with additional arguments. This breaks binary compatibility, but there are other ABI breaking changes in the upcoming release, so now is the time to do it.
-
This is for protection against future ABI breaking changes.
-
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.
-
This is useful only for debugging the linearization code.
