hi'yall
i am tinkering with zoom and pan buttons.. and come across a slight problem..
1. the pan button:
I don't want to make 4 buttons for North,South, East, West directions, but rather a button which when pressed, the result will be the same as if the user pressed down the ALT-key.

2. the zoom reset button
Here i dont want the result be the same as when the user right-clicked the mousebutton and chose Original View

I could of course make a function like i have found:
function reset()
{
svgdoc=htmldocument.embeds[0].getSVGDocument();
root=svgdoc.firstChild();
root.currentTranslate.x=0;
root.currentTranslate.y=0;
root.currentScale=1;
}
But this only resets the scale and translate.. I want the original view..

Anyone got any ideas?

thanks in advance,
Ronny

If you don't modify viewBox attribute with this function reset() you get original view ...
If you play with viewBox, keep values before changing them and put them to reset.
