This overrides file adds a few small helper functions to the gobject-introspection binding for libvips. It has been tested with python2.7 and python3.4 and may work for other versions.

There's a chapter in the libvips API docs on these overrides, see "Using libvips from Python".

vips-x.y.z/test has a test suite. Again, the test suite works with python2.7 and python3.4.

libvips need to be built and installed.

The libvips typelib, Vips-8.0.typelib, needs to be on your GI_TYPELIB_PATH. It is typically installed somewhere like /usr/local/lib/girepository-1.0

You need pygobject-3.0. To confirm that it's installed, check that your Python dist-packages area has a directory called gi. For example:

ls /usr/lib/python2.7/dist-packages/gi

Vips.py needs to be in the overrides directory of your gobject-introspection pygobject area, for example:

sudo cp Vips.py /usr/lib/python2.7/dist-packages/gi/overrides

or

sudo cp Vips.py /usr/lib/python3/dist-packages/gi/overrides

You can optionally pre-compile this file for a small speedup.
