 ### Remarks regarding OFD
 
-Starting from the [version 24.12](https://releases.groupdocs.com/viewer/net/release-notes/2024/groupdocs-viewer-for-net-24-12-release-notes/), the GroupDocs.Viewer started to support the OFD (Open Fixed-layout Document) format, defined by GB/T 33190-2016 aims to replace PDF in Chinese public institutions. For processing _all_ the documents of this format the GroupDocs.Viewer requires that font [SimSun.ttf](https://learn.microsoft.com/en-us/typography/font-list/simsun) must be installed in the operation system. When using Microsoft Windows this should not be the problem, because the SimSun is preinstalled in all the Windows versions and editions starting from the _Windows 7_ (for example, _Windows 7_ has preinstalled SimSun version 5.03, while _Windows 10_ — SimSun version 5.16). But on the Linux SimSun is usually not installed, and when trying to process such a file on Linux, a `GroupDocsViewerException : Could not load file. File is corrupted or damaged. - Font SimSun was not found` exception will be thrown.

-In order to view and save arbitrary OFD file on Linux, the SimSun.ttf font should be loaded to the GroupDocs.Viewer using the [`FolderFontSource`](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.fonts/folderfontsource/) class and [`FontSettings.SetFontSources`](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.fonts/fontsettings/setfontsources/) method, and this should be done _before_ instantiating a `Viewer` class with OFD file. Article ["Set custom fonts"](https://docs.groupdocs.com/viewer/net/set-custom-fonts/) describes setting a custom font in detail, but a short example of setting a SimSun and saving OFD to HTML on Linux is below:
