Replace missing font Leave feedback

You can specify the default font name for a document. GroupDocs.Viewer uses this font during rendering instead of any not installed fonts. For example, if the document includes a font containing non-English characters, specify the default font name to ensure that GroupDocs.Viewer replaces any missing font with one which has the same character set.

The following code snippet shows how to set the default font name:

import com.groupdocs.viewer.Viewer;
import com.groupdocs.viewer.options.HtmlViewOptions;
// ...

try (Viewer viewer = new Viewer("sample.pptx")) {
    HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources();
    viewOptions.setDefaultFontName("Courier New");
    viewer.view(viewOptions);
}
