As long as you are in Edit mode, marks can be modified. There are two ways to modify marks:

• The first is to use ART Forms property dialogs or Annotator property dialogs.
• The second is to use mark objects properties and methods. 

Geometric changes (like moving and resizing) are done automatically, as a result of ART Forms implementation, as shown in Creating a Mark via the ToolBar. To make other changes to a mark, your application makes a simple call to the mark's properties and methods.

The technique for modifying marks via function call is used in the ART Forms or Annotator dialogs' code. The marks attributes can be modified by changing their properties and using their methods.
