+## Skip font license verification when rendering XPS and OXPS files
+
+If an XPS or OXPS file contains a font that cannot be embedded due to licensing restrictions, GroupDocs.Viewer throws an exception at runtime. If you have a license for this font, enable the [PdfOptions.DisableFontLicenseVerifications](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.options/pdfoptions/disablefontlicenseverifications) option to skip font license verification.

+## Enclose images in SVG when rendering PDF and Page Layout files
+
+By default, when rendering to the PDF and Page Layout file formats, all images are combined into a single PNG file, which serves as the background for the output HTML document.
+
+The [PdfOptions.WrapImagesInSvg](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.options/pdfoptions/wrapimagesinsvg) option allows you to wrap each image in the output HTML document with an SVG tag to improve output quality.
+
+This option is available when rendering PDF and Page Layout file formats to HTML with embedded or external resources.
