public class ResourceType
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.
/// This will separate image loading logic from the rest of the document construction.
