Annotation Automation Object
(Document and Medical Imaging toolkits)
The annotation automation object (ANNOBJECT_AUTOMATION) is an object that lets you maintain default properties when using the automated annotation functions. This object has no position or dimensions. It is never placed in a container, but is associated with a root container using the L_AnnSetAutoContainer function.
Any properties that you set in the automation object become the default values for any new objects that are inserted into the associated container. In addition to the properties of other object types, the automation object also has properties, such as the default toolbar selection, that control the automated user interface.
This object has an automation tool property that you can use without implementing the toolbar. For example, if you want to supply your own toolbar or menu options, you can use the automation object alone to keep track of the tool selection.

Alpha Background Fill Option
Annotation Rotate Option
Annotation Side Handles

For more information about these features, refer to Annotation Features
If the annotation objects are container, automation, text, text pointer, stamp, note, pushpin, or button objects it is possible to use the L_AnnGetTextOptions and the L_AnnSetTextOptions functions to set the objects to show or hide the text and to set the color of the text. In addition, if the annotation objects are text or stamp objects these functions can set the objects to show or hide the borders of the object. Note that these features must be enabled using the L_AnnSetOptions function.
The L_AnnSetFillMode and the L_AnnGetFillMode support the ANNMODE_ALPHA fill mode. Before calling these two functions, enable the alpha background fill mode by calling the L_AnnSetOptions function.
