I hope no one minds this announcement. We've just released a new stable version of vips, 7.16.2, that improves the Python binding quite a bit. Good things about vips: * fast, since it's written in C and has good SMP support * low memory use, especially for large images and complex processing, since it is demand-driven and keeps source images on disc where possible * many pixel formats, from 8 to 128-bit pixels, and any number of image bands * >300 image processing operations available in Python * LGPL license Bad things about vips: * no Python binding for Windows (though it ought to be easy to build) * this new version is not yet available in all linuxes so you might need to compile from source * the Python binding is generated automatically from a C++ binding and isn't very Pythonesque More detail and benchmarks here: http://www.vips.ecs.soton.ac.uk/index.php?title=Python New stuff in this version: * The varargs parts of the C++ API are now wrapped in Python, so you can do things like building masks from lists: mask = VMask.VIMask (3, 3, 2, 0, [-1, -1, -1, -1, 16, -1, -1, -1, -1]) To make a 3x3 integer convolution mask, with scale == 2. * The VImage class now has .tobuffer(), .frombuffer() and .tostring() and .fromstring(), so you can efficiently move images between PIL and VIPS. There are also a couple of utility functions to convert VIPS headers to PIL headers and back. There's some sample code in SVN: http://vips.svn.sourceforge.net/viewvc/vips/vips7/branches/vips-7.16/python/test/pilvips.py?view=markup Although it won't copy over image metadata, like EXIF and ICC profiles, sadly.
