preserve mouseEvent while converting svg to jpeg
hi!
I am a newbie SVG/Batik user.
I have a SVG doc (with just one circle element in it, onmouseover, the size changes).
I use batik-rasterizer to convert the svg to jpg. Now I have lost the ability to track the mouse events.
Is there a way to retain the mapping while converting to jpg.
your help is greatly appreciated.
thanks
Priya
from the sample---
<circle onmouseover="circle_mouseover(evt)" cx="460" cy="400" r="10" fill="red"/>
<!-- ECMAScript -->
<script type="text/ecmascript">
var svgns = "http://www.w3.org/2000/svg";
function circle_mouseover(evt) {
if ( window.svgDocument == null )
svgDocument = evt.target.ownerDocument;
var circle = evt.target;
var currentRadius = circle.getAttribute("r");
text.setAttribute("r", currentRadius*2);
}
}

yes, I think so. batik-rasterizer creates static images (jpeg, png, pdf,
etc.). It doesn't create interactive output currently. Someone please
correct me if I'm wrong.
It might preserve links if you convert it to PDF (but I am not sure
about that). You'd need to test it.

Hello Andreas,
Yes, I am hoping batik-rasterizer will allow me to specify that I want
to preserve the image map, so that I could write event handlers.
Say if I have hrefs in my original SVG, would I lose its hypertext
capability once I convert it to a jpg?
thanking you

Hi Priya,
jpg is a static image format. How can you retain the mouse-events?
Are you expecting batik-rasterizer to create an HTML image map? I don't
think it does that.

Is the problem that after you have generated the JPG the SVG document
is no longer responsive to mouse events (in the Canvas), or is the
problem that the JPG is not responsive to mouse events when you view it?
You can fix the first by cloning the document before giving it to
the Transcoder (see the DOM deepClone method). The second is impossible
to fix, JPG is a static format - it simply can't do what SVG can do...
