Whats new in version 5.1.2:
- New example program: pdf-split-pages: efficiently split PDF files into individual pages.
- Bug fix: don\'t fail on files that contain streams where /Filter or /DecodeParms references a stream. Before, qpdf would try to convert these to direct objects, which would fail because of the stream.
- Bug fix: if the last object in the first part of a linearized file had an offset that was below 65536 by less than the size of the hint stream, the xref stream was invalid and the resulting file is not usable. This is now fixed.
Publisher review:QPDF provides many useful capabilities for developers of PDF-producing software or for people who just want to look at the innards of a PDF file to learn more about how they work.
It can encrypt and linearize files, expose the internals of a PDF file, and do many other operations useful to end users and PDF developers.
QPDF includes support for merging and splitting PDFs through the ability to copy objects from one PDF file into another and to manipulate the list of pages in a PDF file. The QPDF library also makes it possible for you to create PDF files from scratch. In this mode, you are responsible for supplying all the contents of the file, while the QPDF library takes care off all the syntactical representation of the objects, creation of cross references tables and, if you use them, object streams, encryption, linearization, and other syntactic details.
Operating system:Mac OS X
