Assembly: DevExpress.Office.v19.1.Core.dll
Declaration
Remarks
Create a class that implements the IUriProvider interface to enable specify custom locations for exported images and styles. Call the IUriProviderService.RegisterProvider method to register the target service.
Tip
A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E1726.
Example
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.
Note
The complete sample project How to retain the original image URI in an HTML document is available in the DevExpress Examples repository.
