PDF to Image Conversion, Image and Text Extraction, Form, Concatenate, Append and Insert Features have been Improved in Aspose.Pdf.Kit for .NET.
Memory utilization and performance have been improved for the Concatenate, Append and Insert methods. However, if you want to perform these operations on a large number of files, we would recommend you to use files as an array instead of using memory streams to get better results.
It is not uncommon to use Adobe Reader Extensions for PDF Forms; we have enhanced Aspose.Pdf.Kit for .NET to support reader extensions. Now, you can use the Form.Save() method to save the filled form while keeping the reader extensions enabled, instead of using the second overload with SaveOptions parameter; this overload is deprecated.
You can see the complete list of changes and download the latest version from the Aspose.Pdf.Kit for .NET download section.
