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.
新功能
- [新功能] 为每个格式系列引入不同的字体类型 (VIEWERNET-5486)
- [新功能] 在获取 WordProcessing 系列格式的全部字体时列出替代字体 (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 the GroupDocs.Viewer is now possible to list and return the 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.
