Behavior changes

  • In this version we’ve improved viewing of Visio documents - now you can choose what to render: Visio figures or Visio scheme(diagram), also Visio figures will be rendered automatically if Visio document does not contain scheme pages.

Changes in the public API

GroupDocs.Viewer.FileType

Field was added to GroupDocs.Viewer.FileType class that reflects new file formats that we’re supporting starting from v20.9.

/// Learn more about this file format <a href="https://wiki.fileformat.com/image/psb">here</a>.
