Lane Cove, Australia, May 05, 2016 --(PR.com)-- What's New in this Release?

Aspose team is pleased to announce the release of Aspose.Pdf for .NET 11.4.0. It offers some new features as well as enhancements to previously supported functionalities. The capability to add hidden text is one of the major New Features introduced in this release. Furthermore, It also has introduced the capability to use PDF file objects after calling ProcessPragraphs() method which is not possible with earlier release versions. In order to add hidden text, set TextState.Invisible property to ‘true’ for the added text. TextFragmentAbsorber finds all text that match pattern (if specified). Please note that hidden text in the document will be invisible for end user while viewing the document with PDF reading software (e.g. Acrobat Reader). But it can be found using text search. There are several ways to make text invisible for end user in PDF and it has implemented one of those techniques. However the text added through Aspose team approach can be found using TextFragmentAbsorber and can not guarantee that any hidden text added by third party applications can be found using same approach but in case users encounter any issue, please share the resource file and Aspose team can further investigate the scenario. The ProcessPragraphs() method was introduced to calculate objects placed inside PDF file and in case Aspose teamf need to have page count information during PDF file generation, this method can be used as it manipulates file objects and returns the desired information. In earlier release versions, once this method was called, the file objects could not be accessed any further. So if users need to add any new object to existing page instance, it was not possible and users had to have a new Page instance where objects can be placed. Nevertheless, starting this new release, users can utilize same Page objects even after calling the ProcessPragraphs() method. As well as the enhancements and features discussed above, there have been specific improvements regarding PDF to PDF/A, Multi-Column PDF, FootNote rendering, generation of large table objects inside PDF, XFA Form to Standard Acro Form conversion, PDF to Image, PDF to HTML, HTML to PDF conversion, Text replacement and rendering PDF files to XPS format conversion. The list of important new and improved features are given below:

• Add and search hidden text in PDF document for post processing
