We have also introduced a feature to highlight text in an existing PDF file. This feature can be used in two ways: you can either simply highlight the text using any color or hide a particular string by using black color. We have used the existing ReplaceText method to introduce this new functionality.
The performance of PdfConverter and PdfFileEditor classes has been enhanced. In addition to that, we have improved concatenate, import XML, PDF to image conversion and PDF printing features. Text replacement feature has also been enhanced to work properly with non-English languages like Norwegian, Russian and Swedish.
You can see the complete list of changes and download the latest version from the Aspose.Pdf.Kit for .NET download section.
