Refer to the following help topic for details on how to use GroupDocs.Viewer to load and view PDF files: Render PDF documents as HTML and image files.

Starting from the version 24.12, 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 must be installed on the operating 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 class and FontSettings.SetFontSources method, and this should be done before instantiating a Viewer class with OFD file. Article “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:

using GroupDocs.Viewer;
using GroupDocs.Viewer.Options;
using GroupDocs.Viewer.Fonts;
// ...

//Put a SimSun.ttf to folder
string SimSunFolderPath = "full-valid-path\folder-with-SimSun-inside";
FolderFontSource fontSource = new FolderFontSource(SimSunFolderPath, SearchOption.TopFolderOnly);
FontSettings.SetFontSources(fontSource);

using (Viewer viewer = new Viewer("Input-document.ofd"))
{
    HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();
    viewer.View(viewOptions);
}

Imports GroupDocs.Viewer
Imports GroupDocs.Viewer.Options
Imports GroupDocs.Viewer.Fonts
' ...

' Put a SimSun.ttf to folder
Dim SimSunFolderPath As String = "full-valid-path\folder-with-SimSun-inside"
Dim fontSource As FolderFontSource = New FolderFontSource(SimSunFolderPath, SearchOption.TopFolderOnly)
FontSettings.SetFontSources(fontSource)

Using viewer As Viewer = New Viewer("Input-document.ofd")
	Dim viewOptions As HtmlViewOptions = HtmlViewOptions.ForEmbeddedResources()
	viewer.View(viewOptions)
End Using
