Scaling a bitmap in a picturebox

Hi,

I'm writing a program that based on input will create a document. It is
something simulair as a printing example.
In MS Word when you click on the shown document you can zoom in and if you
click again you'll zoom out again.

This is what I would like to do as well.
I draw the document in a bitmap, since all the information is drawn from a
database and on the form it is shown in a picturebox.

So what I'm trying to find out is how I can zoom in a certain factor by
clicking somewhere in the document.
If I use the SCALE method I can zoom in and out but how can I move the
bitmap so that the point clicked on is shown in the center of the
picturebox.

Please give me some directions on how to do this?

thanks,
Eric
