New features and improvements

Improved PDF graphics rendering (preview)

Graphics rendering for PDF files has been improved with a new optional rendering mode, PdfRenderingMode.Apryse. This mode uses Apryse technology to much more accurately render the content of PDF pages to images and vector graphics. This feature is currently a “preview” that will be iterated further in future releases.

You can enable this mode by setting pdfRenderingMode in web.xml to “Apryse”.

Note: If you are using Maven to add VirtualViewer to your project, it will need a reference to the PDFNet repository. Add these lines near the top of your pom.xml file:

  <repositories>
    <repository>
      <id>pdftron</id>
      <name>PDFNet Maven</name>
      <url>https://pdftron.com/maven/release</url>
    </repository>
  </repositories>

Deprecation notice

The “Legacy” PDF rendering mode is no longer maintained and will be removed in a future release.
