Linearize PDF files, protect PDFs with AES encryption, optimize images in PDFs

Updated on July 8, 2011

I am pleased to announce that we’ve just released new major version of Docotic.Pdf library.

The Docotic.Pdf 3.0 adds support for advanced password protection. Now you can not only open but also create PDF files encrypted with AES 128 bit algorithm. And we’ve also added PdfDocument.IsPasswordProtected method that is useful if you need to know is a PDF requires a password in order to be opened.

Another major new feature is the ability to linearize PDF files and check if a file is linearized. As you know, linearization (also called Fast Web View optimization) helps to produce PDF files optimized for viewing in browser. We are sure you’ll find this new feature useful.

Starting with Docotic.Pdf 3.0 you can optimize images before adding them to PDFs and even change images in existing PDF files. Please take a look at RecompressWith* family of methods in PdfImage class and new Add single image frame to PDF document sample.

The new version of the library introduces support for Save Options. Using this feature you can fine-tune how PDF documents will be saved by the library. You can reduce size of PDF files or on the contrary save files in a human readable form (it may be useful for debugging purposes).

There are other improvements and bug fixes of course. As always, we encourage you to download and try the new version.
