But the documention says:
------------------------------------
public void set(java.awt.image.BufferedImage image)
Sets this image component to the specified BufferedImage object. If the
data access
mode is not by-reference, then the BufferedImage data is copied into
this object. If
the data access mode is by-reference, then a reference to the
BufferedImage is
saved, but the data is not necessarily copied.
Parameters:
image - BufferedImage object containing the image. The format and size
must be the
same as the current format in this ImageComponent2D object.
Throws:
RestrictedAccessException - if the method is called when this object
is part of
live or compiled scene graph.
-----------------------------------------------------
So you can't call it in a live or compiled scene graph !

Paul
