Form flattening and other new features in Docotic.Pdf 4.8

December 6, 2015

We released a new version of Docotic.Pdf library on our site and on NuGet.

This version adds the ability to flatten PDF forms. Flattening locks controls from editing. Flattening can significantly reduce file size if the document is then saved with the PdfSaveOptions.RemoveUnusedObjects option set to true. To flatten form fields in a PDF file, please use the PdfDocument.FlattenControls method.

We also added support for list boxes (there are the Listboxes sample illustrating how to create them). The PdfCheckbox got a new ExportValue property. You can use this property to extract the export value of a checkbox.

Docotic.Pdf 4.8 fixes the number of issues related to processing of controls and widgets. The new version parses, draws and fills PDF forms better than before.

The new version fixes some issues related to the extraction of JPEG and CCITT (Fax) images. Text drawing and text extraction also got better. And the library is now more prepared to work with not completely correct PDFs.

Better images and text processing in Docotic.Pdf 4.7

August 31, 2015

We released a new version of Docotic.Pdf library on our site and on NuGet.

The new version adds the ability to specify the place where the library should keep its intermediate data. You can tell the library to keep all the data in memory or to keep smaller streams in memory and other streams in temporary files. The latter is the default option. You can create your own stream provider and tell the library to use it. You can read more about this in documentation for the IPdfStreamProvider interface and PdfConfigurationOptions class.

We fixed a number of issues related to image processing. The library now draws and extracts images better, spends less memory to recompress them and more prepared to handle not exactly correct images.

Docotic.Pdf 4.7 fixes some text related issues and, thanks to some of our customers, we could improve support for CJK text drawing and extraction.

This version also better draws documents with transparency groups and documents which use blend modes.

And as always, we improved the library so it can work with more of those not completely correct PDFs created by unknown generators.

Improved memory management in Docotic.Pdf 4.6

May 11, 2015

The new version of the Docotic.Pdf library got published on our site and on NuGet.

Substantial amount of improvements in Docotic.Pdf 4.6 is related to memory management. Latest version uses much less memory to open or draw PDF documents. Extraction of JPEG 2000 and JBIG2 images also uses less memory in Docotic.Pdf 4.6.

The new version also contains improvements to text extraction, text rendering and font processing features. Version 4.6 handles Japanese text better than any previous version.

We also dedicated some time to rendering features of the library. The latest release draws text, patterns, XObjects, and forms better. Just better.

Docotic.Pdf 4.5 processes fonts and images better

February 1, 2015

The new version of the Docotic.Pdf library is available on our site and on NuGet.

Docotic.Pdf 4.5 extracts and draws images faster. Especially images with masks. The new version also processes Type 0 fonts faster.

We added the ability to create and use L*a*b* colors and color spaces in the newest version of the library. Take a look at PdfLabColorSpace and PdfLabColor classes.

As usual, there are a number of bug fixes in version 4.5. Most of the bugs affected the quality of PDF rendering, so now the library draws PDFs correctly in more cases than before. Also, as usual, the new version improves support for semi-broken PDFs created by some buggy and usually anonymous generators.
