Adding a custom annotation type to your application

You can add a custom annotation type to your application.

To add a custom annotation type to the annotation services, complete the following steps. See the Application Programming Reference for details about API usage.

Remember: This custom annotation cannot be saved because the built-in annotation engine will not support or understand it.

Create a subclass of CMBPageAnnotation.

public class TImageAnnotation extends CMBPageAnnotation

Define a constant for the custom annotation with a value larger than 100. The range of 1 to 99 is reserved.
```
public static final int ANN_IMAGE = 101;
```

Override the following methods of CMBPageAnnotation.

    public void draw(Graphics2D g2);
    public void drawOutline(Graphics2D g2);
    public CMBPropertiesPanel getAnnotationPropertiesPanel();

Implement the CMBAnnotationPropertiesInterface interface to create the properties window. The properties window appears when a user chooses to edit the custom annotation properties.
Provide set and get methods specific to the custom annotation properties.

Add the custom annotation type.

annoServices.prepareToAddAnnotation(TImageAnnotation.ANN_IMAGE,
"TImageAnnotation",1);

The annotation type sample TImageAnnotation is included in the samples directory. The sample demonstrates how to add a custom annotation type to the annotation services.
