This is excellent, your "survey" API is much friendlier than the
straight SWIG-generated wrapper around img.h. I had to specify the
location of my Python header files to compile (Ubuntu Feisty), and
have attached a Makefile to build the Python module.

---- Makefile ----

# Makefile for survex Python module

# Location of Python header files
PYINCLUDE=/usr/include/python2.5/


.PHONY: all python

all: python

python: _survex.so

survex_wrap.c: survex.i
	swig -python survex.i

survex.py: survex_wrap.c

img.o: img.c img.h
	gcc -c -fPIC img.c

survex_wrap.o: survex_wrap.c
	gcc -c -fPIC survex_wrap.c -I$(PYINCLUDE)

_survex.so: img.o survex_wrap.o
	gcc -shared img.o survex_wrap.o -o _survex.so


clean:
	rm -f *.o *.so *.pyc survex_wrap.c survex.py
