Rich Text Editor for WinForms - Retain the Original Image URI in an HTML Document

This example demonstrates how to use the DocumentImage.Uri property to set the image's src attribute when a document is saved in HTML format. You can switch on the HtmlDocumentExporterOptions.EmbedImages option to observe that the custom URI provider is idle for embedded images.

The project implements a custom class with the IUriProvider interface and registers it as the IUriProviderService provider.
