The text annotation object (ANNOBJECT_TEXT) is a rectangle containing a character string with font properties. The text will wrap on word breaks within the object's specified rectangle. With the automated functions, the user clicks and drags to specify the rectangle in the current window. A dialog box then lets the user enter the text.
The class for Text Annotation objects is LAnnText.
You cannot flip or reverse a text object. If you flip or reverse a container that includes a text object, the text will move to the new position, but will retain its orientation.
For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
With low-level functions, you must specify the rectangle that contains the text. Other applicable properties have the following defaults, which you can change:
