Hello everyone.

I am a recent user of Batik , and while enjoying it , i encounter severeal
dificulties.

I want to get from a image in SVG the outlines of VISIBLE shapes.
Example:

I have a huge yellow filled square stroked with black, wich totaly contains
a yellow smaller square stroked and filled in yellow ( not visible).

Is there an easy way of getting only the black outline of the big square
ignoring other information ( inclusive the yellow color and the outer
smaller square element) ?

The only solution i have at the moment is to convert the image to JPEG and
use countour extraction algoritms... not to bright.

I would apreciate any help on this or where to view some batik examples
because this mailing list is the only source of Batik information i have.

Kind regards, Filipe Quinaz
