Rectangle Annotation Object

Note:

This topic is for Document/Medical only.

The rectangle annotation object (ANNOBJECT_RECT) is a simple rectangle. With the automated functions, the user clicks and drags to specify the rectangle in the current window.

With low-level functions, you must define the size and position of the rectangle. Other applicable properties have the following defaults, which you can change:

Visible

Defaults to FALSE. It can be changed using the AnnSetVisible method.

Selected

Defaults to FALSE. It can be changed using the AnnSetSelected method.

Name

Defaults to empty string. It can be changed using the AnnSetNameOptions.

Defaults to 0.75 points. It can be changed using the AnnSetLineWidth method. (Note that when displayed, the line must have a minimum width of 1 pixel.)
