Hi, I installed the gems but I immediately run into this:

C:\Inline\png-1.0.0>ruby -Ilib example/profile.rb
example/profile.rb:8:in `draw': undefined method `to_blob' for 
#<PNG:0x28c7b28>
(NoMethodError)
        from example/profile.rb:15
        from example/profile.rb:15

... on Windows.

I get the same thing in cygwin:

$ time ruby -Ilib example/profile.rb
example/profile.rb:8:in `draw': undefined method `to_blob' for 
#<PNG:0x28c7b28>
(NoMethodError)
        from example/profile.rb:15
        from example/profile.rb:15
real    0m2.361s
user    0m0.015s
sys     0m0.046s

The rdoc does not show a a 'to_blob' method for PNG

Any idea?
