zooming problem on pc
Hello,
I display a world map with several layers through batik
with a set of layers as default and others optional
If I zoom in on the mac everything is fine
if I zoom in on the pc(win2k) the optional layers, even if shown
disappear and just the default
layers of the map are displayed?
Any suggestions?
cheers
Georg

no, is used -Xmx128m and I noticed that it is sometimes working and
sometimes not, so I guess its a OS problem and depends on how many apps
are in use
cheers!

Is it possible you are running out of memory?
On my system the map seems to be on the _very_ hairy edge of
running out of memory. If it ran out of memory 1/2 way through
rendering it would most likely just display what it had gotten to.
Try using '-Xmx128m' or something to up the max heap size.

Ah!
We are working on different problems. I need to change visibility on
some elements when the picture is zoomed.
One issue I keep hitting that may be related to your issue is to always
make sure that the page is finished rendering before doing the
"invokeLater". Otherwise, the UpdateManager may be null. This has caused
me no end of grief.

via an ActionListener activated from a JCheckBox
I actually don't recognize if the picture has been zoomed, maybe that's
the pc problem

I actually need to do something similar. How are you recognizing that
the picture has been zoomed? Or put another way, how is the code below
triggered?

custom app on JSVGCanvas
the built in zoom (ctrl + left mouse button)
/**
shows the cities
*/
public void showcapitals(){
UpdateManager um = svgCanvas.getUpdateManager();
RunnableQueue rq = um.getUpdateRunnableQueue();
rq.invokeLater( new Runnable( ){
public void run( ){
String id = "cities";
Element elt = svgdoc.getElementById(id);
if(elt != null){
elt.setAttributeNS(null, "visibility", "visible");
}
}
});
}

Not based on this. How are the optional layers turned on/off?
How is zoom done? Is this in Squiggle or some custom app built
on the JSVGCanvas, or rasteriser?
