We are excited to release another monthly release, version 17.9, of GroupDocs.Viewer for .NET. This version allows you excluding fonts from HTML representation of the document and saving them as external resources. Also, we have extended the support of responsive HTML for MS Visio documents, SVG images, MS Word documents, Open Office Text and Rich Text document format. The latest version also includes some important bug fixes for the issues found in prior releases. We recommend you to upgrade to the latest version for an improved experience.
Excluding Fonts when Rendering to HTML
Embedded fonts increase the size of the rendering result, therefore, in order to prevent adding fonts into HTML, we introduced ExcludeFonts property of HtmlOptions class. For more details on excluding fonts from HTML representation, please visit this documentation article.
GIF Images with Animation in Output HTML
In earlier versions, when rendering document into HTML, GIF images were converted into PNG format. Therefore, the images were displayed without animation in the resultant HTML. From version 17.9, we have added the support of saving the GIF images as it is when rendering the documents into HTML.
