imread: Image reading library

Package Documentation

mahotas-imread: Read Image Files

Mahotas-imread is a simple module with a small number of functions:

Reads an image file
Reads an image file with multiple images. Currently, TIFF and STK (a TIFF
sub-based format) support this function.
Writes an image file

Example (which uses `mahotas <http:"" software="" 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 <http:"">`__] or packages from
others [`scikit-image <http:""/>`__, for example].

The relationship with numpy is very contained and this could be easily
repurposed to load images in other frameworks, even other programming

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 build

and install with::

python install

On Windows, you can also just download a pre-built package from `C. Gohlke's
repository <http:"" ~gohlke="" pythonlibs="" #imread="">`__
