DrawString Method

[Mark Keats]

Hi there,

I have some code for an ASP.Net page that produces an image of an e-mail
address to prevent those programs that spider the net for e-mail
addresses on pages grabbing it.

The code is as follows (but on my version it gets the e-mail address
from a database rather than QueryString).

How can I crop the image to the exact size of the text as if the e-mail
address is short there is excess whitespace and if it is long it
over-runs the image.

Any help would be great!
