Re: Problem Using the getIntersectionList method

Thanks a ton.

I am assuming I should keep checking the nightly builds listed in the CVS Repository for the next release. Is that true?

Thanks again,
TJ Teegan

good to hear.

looking forward to using getIntersectionList() - I think it will be a very useful feature for webmapping applications.

Hi TJ,

I am trying to find all the elements in a given area. I am assuming I should be using the getIntersectionList method, however I must be using it incorrectly because I always get a java.lang.Error when I call it. 


    That's because it isn't implemented yet (except in my local copy
of Batik ;).  I've been working on this for the past couple days.
Expect a delivery shortly (I'm wrapping up a few details with
text and use elements).

Here is an example of the code I am using:

public NodeList myMethod(){
    SVGRect rect;
    SVGElement ele;
    NodeList nodes;

    rect = SVGDocument.getRootElement().createSVGRect();
    rect.setX(0);
    rect.setY(0);
    rect.setWidth(100);
    rect.setHeight(100);
    ele = SVGDocument.getRootElement();
    nodes = SVGDocument.getRootElement().getIntersectionList(rect, ele);
    return nodes;
}

I apologize if this has been covered else where. I searched the mail list archive but was unsuccessful in finding an answer. Any help is appreciated.

Thank you,
TJ Teegan
