May 2022

VirtualViewer® v.5.9

PDF Portfolio Support

  • Easily open all of the files contained in your PDF Portfolios regardless of the file type. Users simply select the paperclip icon on the portfolio tab to open each file in a corresponding tab. As long as the format is supported by VirtualViewer it can be opened in the browser including not only PDF but also Word, Excel, PowerPoint, TIFF and more without the need to rely on the creator application.

Video & Audio Caption Support

  • Custom captions and subtitles can now be displayed for audio and video files. Supply the caption file as a WebVTT format (.VTT) which is then passed through the content handler and the associate captions and subtitles show for the appropriate media file. Please note that VirtualViewer does not currently support auto generating captions.
  • Not all browsers natively support captions for audio players but with this release you can easily enable this functionality through our new Javascript API or via the User Preferences panel.

Customized Media Toolbars

  • Administrators can easily add custom buttons for audio and media controls. For example, if you want to add a button to indicate the viewer’s interest level, you can provide a thumbs up or thumbs down button in the control panel.

Additional OCR language support

  • Administrators can now specify different languages that you want to support in the OCR engine.

Locale Date/Time format

  • When rendering MS Office or eml/msg files in the viewer you can specify how the date and time field appears.

Enhanced Format Support

  • Since VirtualViewer is built on our RasterMaster SDK, all format enhancements are inherent in the viewer. See the RasterMaster enhancements below for specific format updates.

End of Life

New Release Schedule

For 2021, we will be moving from a quarterly release schedule to three times per year. This allows us to sync up both our VirtualViewer and RasterMaster releases on the same schedule, as well as focus more time and resources on each individual release.

Major Version Upgrade

We plan to move to v6.0 by the end of 2022. We are currently in the process of finalizing release plans for the year. We will send out more information when the official date, details, and beta program options are confirmed.

Java 7 End of Life Notice

Snowbound’s policy is to move to the latest Java Long Term Support release 18 months after its original release date, at which point we will no longer support previous releases. This means as of March 2020, we will only support the latest Java Long Term Support Release, Java 11. The last VirtualViewer build to support Java 7 is v5.2.
