Subject RE: How do i Implement Zoom and Pan in my Application
Date Wed, 22 Jan 2003 20:21:43 GMT
Hi Vincent,
The answer is not so easy. Since I fear I have to do a bit of all. I am
using an JSVGCanvas to render dynamically generated svg pictures which
represent Algorithm-animations (for educational use).
First I want the user to have the ability to pan and zoom in the
JSVGCanvas (after pressing a zoom or pan button in the application). 
On the other side I need the ability to resize the svg graphic from my
application and pan it, so that the user sees an "interesting" area. 
I know I am asking much, but a solution to one of my problems would help
me a lot. 
Thanks in advance

Hello Ralf,
Are you trying to zoom and pan trough the Batik APIs or through the 
standard DOM APIs? Or are you trying to let the user zoom and pan in
