Convert PDF to TIFF Using Bradley Algorithm & Add Page Number as Stamp Object using .NET

We are pleased to announce the release of Aspose.Pdf for .NET 11.6.0. It significantly adds improvements in PDF to PDF/A, PDF to TIFF/JPEG and HTML to PDF features. The API has also been greatly improved to handle various complex scenarios which were causing some issues in earlier release versions. Indeed, this version is better and stable release, as compared to earlier versions. Aspose.Pdf for .NET has been supporting the feature to convert PDF to TIF using LZW compression and then with the use of AForge, Binarization can be applied. However one of the customers requested that for some images, they need to get the Threshold using Otsu, so they also would like to use Bradley. The PageNumberStamp class offers the feature to add Page Number information as stamp object inside PDF document. Prior to this release, the class only supported 1,2,3,4 as page numbering style. However, there has been a requirement from some customers to use custom numbering style when placing page number stamp inside PDF document. In order to accomplish this requirement, NumberingStyle property has been introduced, which accepts the values from NumberingStyle enumeration. As well as the enhancements and features discussed above, there have been specific improvements regarding PDF to PDF/A, PDF to HTML, XPS to PDF, PDF to XPS, HTML to PDF, RedactionAnnotation, Text manipulation and Image placement/manipulation in PDF document. The list of important new and improved features are given below
