Detecting Text Overflow in irregular shapes

[Kevin Maione]

I am considering using Batik / SVG to build a web application that 
merges text and images and displays the results as a JPEG. The 
application allows the users to specify font info including point size. 
One of the requirements is to give an error message if content goes 
outside the boundaries of a specified background area. Can this be done 
using Batik? For example, let us say I have a circle background and 
allow the users to enter multiple lines of text oriented towards the 
middle of the circle. At some point one or more of the lines could get 
long enough to extend past the boundary of the circle. Although I 
suspect I could use some clipping to cut this off I need a way to know 
that the clipping occurred? If the background was rectangular I  could 
take the text and calculate the width / height and figure it out myself. 
But in the case of a non-rectangular background I'm hoping Batik can 
help. Thanks...Kevin
