public class ResourceType
- extends java.lang.Object
Utility class containing constants.
Type of loaded resource.
Example:
Shows how to process inserted resources differently.
public void resourceLoadingCallback() throws Exception {
Document doc = new Document();
// Images belong to NodeType.Shape
// There are none in a blank document
Assert.assertEquals(doc.getChildNodes(NodeType.SHAPE, true).getCount(), 0);
// Enable our custom image loading
doc.setResourceLoadingCallback(new ImageNameHandler());
DocumentBuilder builder = new DocumentBuilder(doc);
// We usually insert images as a uri or byte array, but there are many other possibilities with ResourceLoadingCallback
// In this case we are referencing images with simple names and keep the image fetching logic somewhere else
builder.insertImage("Google Logo");
builder.insertImage("Aspose Logo");
builder.insertImage("My Watermark");
Assert.assertEquals(doc.getChildNodes(NodeType.SHAPE, true).getCount(), 3);
doc.save(getArtifactsDir() + "DocumentBase.ResourceLoadingCallback.docx");
}
private static class ImageNameHandler implements IResourceLoadingCallback {
public int resourceLoading(final ResourceLoadingArgs args) throws URISyntaxException, IOException {
if (args.getResourceType() == ResourceType.IMAGE) {
// builder.InsertImage expects a uri so inputs like "Google Logo" would normally trigger a FileNotFoundException
// We can still process those inputs and find an image any way we like, as long as an image byte array is passed to args.SetData()
if ("Google Logo".equals(args.getOriginalUri())) {
args.setData(DocumentHelper.getBytesFromStream(new URI("http://www.google.com/images/logos/ps_logo2.png").toURL().openStream()));

}

args.setData(DocumentHelper.getBytesFromStream(getAsposelogoUri().toURL().openStream()));
return ResourceLoadingAction.USER_PROVIDED;
}
// We can find and add an image any way we like, as long as args.SetData() is called with some image byte array as a parameter
