+ <warning>
+ To work with graphic objects HSLF uses Java2D classes
+ that may throw exceptions if graphical environment is not available. In case if graphical environment
+ is not available, you must tell Java that you are running in headless mode and
+ set the following system property: <code> java.awt.headless=true </code>
+ (either via <code>-Djava.awt.headless=true</code> startup parameter or via <code>System.setProperty("java.awt.headless", "true")</code>).

<p>
When you add a shape, you usually specify the dimensions of the shape and the position
of the upper left corner of the bounding box for the shape relative to the upper left
