Text Pointer Annotation Object

Note: This topic is for Document/Medical only.

The text pointer annotation object (ANNOBJECT_TEXTPOINTER) is a rectangle with a line that starts from one of the four corners. The other endpoint of the line can be moved to point to anything on the underlying image. The rectangle contains 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 drag to specify the rectangle in the current window. After letting up on the mouse button, the rectangle is specified. Moving the mouse now specifies the line, with a final mouse click defining the line.

You can flip or reverse a text pointer object, but you cannot rotate it. If you flip or reverse the text pointer object, the text orientation does not change. To change the text orientation, see Text Dialog Box for Annotations.

With low-level functions, you must specify the rectangle that contains the text, and the pointer endpoint of the line. See AnnSetPoints for more details. Other applicable properties have the following defaults, which you can change:

Visible	Defaults to FALSE. It can be changed using AnnSetVisible.
Selected	Defaults to FALSE. It can be changed using AnnSetSelected.
Name	Defaults to empty string. It can be changed using AnnSetNameOptions.

Line style	Defaults to solid. It can be changed using the AnnSetLineStyle method.
ROP2 code	Defaults to Copy. It can be changed using the AnnSetROP2 method.
