Subject: module / class best practices

I'm writing some code that generates an image file based off either a
binary file or shared memory.

I figure that I need three functions:

generate_image_from_file # public
generate_image_from_shmem #public
generate_image # private?

The user would call either generate_image_from_file or
generate_image_from_shmem.  Once the data has been loaded, both
functions would call generate_image to write the image to a file
somewhere.

Would this be best written as a class inside a module?  Or a set of
functions inside a module?  I'm not really storing any data, and
there's no point in keeping the object around after the image is
generated.

Thanks,
Joe
