Below you will find sample code for creating non-automated annotations using LEADTOOLS 19 in Java. This simply creates a blank RasterImage in which annotations are then created and rendered to the image.

Code:


static void createAnn(){
		RasterCodecs codecs = new RasterCodecs();
		
        RasterImage image = RasterImage.create(750, 900, 24, 150, RasterColor.fromHtml("White"));
		System.out.println("RasterImage created successful");
		
		double inch = 720;
		AnnContainer container = new AnnContainer();
		container.setSize(LeadSizeD.create(8.5 * inch, 11 * inch));
		
		AnnRectangleObject rectangleObject = new AnnRectangleObject();
		rectangleObject.setRect(LeadRectD.create(3 * inch, 3 * inch, 1 * inch, 1 * inch));	
		container.getChildren().add(rectangleObject);
		System.out.println("Rect created successful");		

		AnnNoteObject noteObject = new AnnNoteObject();
		noteObject.setRect(LeadRectD.create(0, 0, 800, 800));
		noteObject.setText("LEADTOOLS");
		container.getChildren().add(noteObject);
		System.out.println("Note created successful");	
				
		// Burn the annotations on this image
		AnnJavaRenderingEngine renderingEngine = new AnnJavaRenderingEngine();
		renderingEngine.renderOnImage(container, image);
		
		codecs.save(image, "C:\\Java_Render.tif", RasterImageFormat.TIF, 0);
		System.out.println("Render successful");

				
		
	}
