It would still be rather easy actually, although admittedly it would be 
more work for the spammer.  Once you know the font being used and have 
a sample of every character in that font (easy) it would not be hard to 
write a program to compare blocks of pixels with those which are 
already known and to reconstruct the email addresses.

It's just about the simplest form of image recognition.
