What?s new in this release?

The latest version of Aspose.Pdf for .NET (9.1.0) has been released. Like in the last few releases, the specific focus of Aspose.Pdf development has been towards the PDF to HTML conversion feature. In adding more value to this functionality we have added a new feature: creating subsequent files with body contents only when converting multi-page PDF to HTML format. In order to accomplish this requirement, a new property, HtmlSaveOptions.HtmlMarkupGenerationMode has been introduced. Further details, can be found in the article on the basics of PDF to HTML conversion in our documentation sections. We received a request regarding printing of PDFs via a Windows Service because System.Drawing.Printing is not supported by Microsoft in a Service. In order to resolve this problem, you need to first convert the PDF file to XPS format using Aspose.Pdf for .NET. Once the PDF file is converted to XPS format, you can use Aspose.Words for .NET to print a document on a server via XPSPrint. HTML to PDF is an important Aspose.Pdf for .NET feature. In this release, we have introduced a new feature regarding resource loading callback when converting HTML files to PDF format. Over the years, Aspose.Pdf for .NET has proved to be a great API for converting PDF files to PDF/A format. In this latest release, we have introduced the support for converting PDF files to PDF/A_3b compliant format. In order to support this feature, the value PDF_A_3B has been added to the PdfFormat enumeration. FDF stands for Forms Data Format, and an FDF file contains form values in a key/value pair. We also know that an XML file contains the values as tags, where, mostly the key is represented as the tag name and value is represented as the value within that tag. Now, Aspose.Pdf.Facades provides the flexibility to convert an FDF file into XML. Conversion of XSL-FO files to PDF format using legacy Aspose.Pdf for .NET (the current Aspose.Pdf.Generator namespace) is one of the salient features of our API and many customers are already using this feature. Now we have also introduced this feature to the Aspose.Pdf namespace. We have introduced a feature that lets you digitally sign PDF documents using time-stamp servers. A new class named TimestampSettings has been added. mAlso please note that the current implementations of encryption/decryption and hashing functions are FIPS compliant. Along with the above listed features, we have made numerous enhancements to PDF to TIFF conversion, working with annotations, bookmark manipulation, filling forms, PDF to HTML conversion, HTML to PDF conversion, PDF to Microsoft Excel worksheet conversion, adding image to PDF file and much more. The list of important new and improved features are given below
