I'm trying to set the viewBox attribute on a document and sometimes I
just get a blank screen.
If I change the size and x,y coordinates of the viewbox it doesn't
repaint but if I just change the viewboxs x,y coordinates everytnig
works fine.
If I add a Thread.sleep(100) in the run method before i change the
attributes everything works fine.
I allso have to remove the attribute before I change it or I get a
nullpointer exception every time.
I'm runnig this from the invokeLater method.
If I add the viewBox attribute to the svg file I get a nullpointer
exception when I try to remove it but if there is no viewbox in the
svg file it doesnt complain about it.
I'm using java 1.5_06 and batik 1.6
canvas.getUpdateManager().getUpdateRunnableQueue().invokeAndWait(new
Runnable() {
public void run() {
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
svgRoot.removeAttribute(SVGConstants.SVG_VIEW_BOX_ATTRIBUTE);
canvas.getSVGDocument().getRootElement().setAttributeNS(
null,
SVGConstants.SVG_VIEW_BOX_ATTRIBUTE,
(character.getPosition_x() - viewWidth / 2) + " "
+ (character.getPosition_y() - viewHeight / 2) + " "
+ viewWidth + " " + viewHeight);
}
});
