Why not? Seems to me all you need to do is:

 withImageSurfaceFromPNG "blah.png" $ \surface -> do
    ...

Lots of code is written this way (create a resource, pass it to a
function and then release it after the function is over.)

Without further context as to what you are doing, I really see no
reason why you would have to use unsafePerformIO at all.
