We’re happy to announce the major release of GroupDocs.Viewer for .NET 25.9, available as of September 2025. This major release delivers two new features with public API changes, one enhancement and 4 fixed bug.

Nuove funzionalità

  • [Nuova funzionalità] Introduce distinct font type for each formats family (VIEWERNET-5486)
  • [Nuova funzionalità] List substituted fonts when getting all fonts for the WordProcessing family formats (VIEWERNET-5484)

Both these features continue to improve the mechanism of extracting and listing used fonts of the loaded document. In short, with VIEWERNET-5484 GroupDocs.Viewer now è possibile elencare e restituire i substitutuion fonts, which are not present in original document, but are used to replace those original fonts, which are missing and thus unavailable on a target machine (where the GroupDocs.Viewer is running). The VIEWERNET-5486 feature improves the public API — instead of a single UsedFontInfo type now there is a IFontInfo interfave and a plenty of its inheritors — one per each formats family. Visit the article “Getting all used fonts in the loaded document ” in public documentation for the further details.
