Link Annotation in Tagged PDF Support & Determine if Text has Underline using .NET

What's New in this Release?

Aspose team is very excited to announce the new version of Aspose.PDF for .NET 18.10. As per regular monthly update process, it has incorporated new features and enhancements in the API as well as several fixes to the reported bugs have also been included in latest release. Latest version of the API has been released with the support of Link Annotation in Tagged PDFs. This support includes various functionalities i.e. adding tagged content with link tag, adding decorated link text content and gets rectangles that bounds link content. It has been working over providing full support for creating Tagged PDF content and hopefully new features would also be a part of next release. Some validations for PDF/UA Format of PDF documents have also been implemented in latest release of the API, such as XObjects Validations and Actions Validations. In order to determine if text has underline, getter for Underline property of TextState of TextFragment has been implemented. There are several serious reasons of using above option because, explicit instruction must be set for searching underlines in the document. As implementation of text underlining is not described in PDF specification, it means a great number of ways exist how text underlining may be implemented in third party documents. Therefore, we cannot give warranties that underlining of text will be found in all cases in source document. Along with the features mentioned above, there are some useful improvements and enhancements included in latest release of the API. Such as Tooltips for WebHyperlink have been improved to show correct behavior, Subscript in LatexFagment has been further improved, Non English characters rendering in PDF document is improved, PDF to PPTX conversion is improved, Text searching scenarios has been taken care of in terms of coordinates extraction, Font handling has been improved, PDF to TIFF Conversion Engine has further been improved, Image rendering while HTML to PDF Conversion is further improved, various improvements have been made for PDF to PDF/A conversion and Memory consumption has further been improvised.
