If you're doing many image transformations, invoking an external program like convert will get expensive due to context-switching. So that's why something like the (not-yet-existent) bindings for ImageMagick-as-a-library might be useful. I agree that laziness probably isn't going to be helpful, but there may be interesting things to be done that are enabled by purity and higher-order-functions. I'm working on the ImageMagick bindings because I'm curious to find out. There are obvious things like being able to define compositions of transformations -- which is easy to do when you're calling library functions in-memory, and less so if you're using a separate executable -- but maybe there are more interesting applications too.
