IO with images and numpy arrays.
Mahotas-imread is a simple module with a small number of functions:
imread: Reads an image fileimread_multi: Reads an image file with multiple images. Currently, TIFF and STK (a TIFF sub-based format) support this function.imsave: Writes an image fileExample (which uses mahotas for Gaussian filtering):
from imread import imread, imsave
from mahotas import gaussian_filter
lena = imread('lena.jpeg')
lena = gaussian_filter(lena.astype(float), 4.)
imsave('lena-filtered.jpeg', lena)
This grew out of frustration at current image loading solutions in Python, in either my packages [mahotas] or packages from others [scikit-image, for example].
The relationship with numpy is very contained and this could be easily repurposed to load images in other frameworks, even other programming languages.
Python versions 2.6, 2.7, 3.3+ are officially supported.

The easiest environment to install mahotas-imread is anaconda, through conda-forge. Just use:
conda config --add channels conda-forge
conda install imread
To compile on debian/ubuntu:
sudo apt-get install libpng12-dev libtiff4-dev libwebp-dev
sudo apt-get install xcftools
To compile on Mac:
sudo port install libpng tiff webp
Either way, you can then compile with:
python setup.py build
and install with:
python setup.py install
On Windows, you can also just download a pre-built package from C. Gohlke's repository
On nix, you can use:
nix-env -iA nixpkgs.python3Packages.imread
or use the pkgs.python3Packages.imread object in your *.nix files.
