Yes the STDIN/STDOUT is pretty kludgy way of interfacing to SANE, but it was
quick and dirty. Now that I have the core objects written like I want
them, I can now go back and figure out how to glue it up using a direct
Actually I think what most Mono programmers do is write a C binding system
object lib that uses simple data types and then write a .NET object which
uses [DllImport] P/Invoke directive on the methods to redirect the calls on
the object to the library.
What I need to do now is read the scanimage source code and understand how
it works so I can understand the headers and write the .NET proxy class and
the lib glue code (no small task!) :-)
