We are pleased to announce the release of version 17.10 of GroupDocs.Viewer for .NET. This monthly release has come with 3 new features and more than 10 improvements and bug fixes. GroupDocs.Viewer for .NET 17.10 allows you to render STL and IFC file formats. Furthermore, settings to hide/show hidden pages have been extended for Microsoft PowerPoint documents. Please continue to read more about the latest version.
Render STL and IFC File Formats
From version 17.10, GroupDocs.Viewer supports rendering of STL and IFC file formats. For more details on supported file formats, please visit this documentation article.
Rendering Hidden Sheets, Slides or Pages
Microsoft Excel, PowerPoint and Visio documents may contain hidden pages (slides or sheets). By default, hidden pages are not rendered. In order to include them into the rendering, set ShowHiddenPages property of the RenderOptions (ImageOptions or HtmlOptions) class as true. This new setting has replaced obsolete CellsOptions.ShowHiddenSheets and DiagramOptions.ShowHiddenPages properties in RenderOptions class.
For more details on rendering hidden pages, please visit this documentation article.
Rendering Worksheets by Dividing into Pages
By default, GroupDocs.Viewer for .NET renders the whole Excel sheet into a single HTML/image page or into a single page of the PDF document. However, the API also allows dividing large Excel sheets into multiple pages. From version 17.10, this feature is supported for rendering the document as PDF and as image with enabled text extraction.

Improved Document Rendering from Stream into HTML
In earlier versions, when we render document from the stream and do not provide document name, API has been suppressing saving resources separately and embedding resources into HTML regardless of IsResourcesEmbedded setting. Since the version 17.10, when document name is not provided, API tries to generate document name from the stream. When that stream is rendered again, API will generate the same name. However, try to avoid not passing document name in cases when document name is known because API does not guarantee that document type will be detected and that document name will be unique for the stream (as in some cases, API may generate the same name for two different streams).
