Type of loaded resource.

Examples:

Shows how to customize the process of loading external resources into a document.

 public void resourceLoadingCallback() throws Exception {
     Document doc = new Document();
     doc.setResourceLoadingCallback(new ImageNameHandler());

     DocumentBuilder builder = new DocumentBuilder(doc);

     // Images usually are inserted using a URI, or a byte array.
     // Every instance of a resource load will call our callback's ResourceLoading method.
     builder.insertImage("Google logo");
     builder.insertImage("Aspose logo");
     builder.insertImage("Watermark");

     Assert.assertEquals(3, doc.getChildNodes(NodeType.SHAPE, true).getCount());

     doc.save(getArtifactsDir() + "DocumentBase.ResourceLoadingCallback.docx");
 }

 /// Allows us to load images into a document using predefined shorthands, as opposed to URIs.
