Perl module wanted

Hey guys, it's me lowering the bar again.

I'm looking for a Perl module that inputs a short bit of text and then outputs a bitmap
image thereof. Anybody know if such a critter exists? (Anyone have experience with 
Image::Imlib2?)

I have an insidious plan for thwarting spammers and this capability is the first step. If
you have ever purchased something via PayPal, you'll note that they make an image of some
authorization numbers and ask you to type in the authorization code. This prevents crooks
from writing programs that "scrape" the authorization code automatically.

Why do I want to mess with this? I want to apply this technique to personal email
addresses. Goto http://steve.poling.info and you'll see my personal email address rendered
in a hard-to-scrape format. (Hehe, I hyperlink a sacrificial "spam-target" address in the
mailto target.) If I can get this module to work, I'll setup a freebie service to give my
friends nifty little hard-to-scrape gif files of their email addresses.

My module would do this:
1) convert input text string to a bitmap.
2) randomly jizzle the individual letter positions
3) xor a patterned background
4) blast some random lines atop the letters
5) generate a bmp, gif, png output file.
6) mail the file to the specified address.
7) sell the address to spammers???? Horrors, NO!

I figure there is probably an image processing Perl module that does most all these steps
individually. Does anybody know of any?

I'd rather not do this in C++ as a matter of principle.

smiles and cheers,

steve
