imread: Image reading library

Package Documentation

Latest Version: 0.5.1

================================
mahotas-imread: Read Image Files
================================

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

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

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

Bug Reports
~~~~~~~~~~~

Please report any bugs either on github or by email to luis@luispedro.org

If you are not sure of whether this is the correct behaviour, you can discuss
this on the

If at all possible, include a small image as a test case.

Travis Build Status
~~~~~~~~~~~~~~~~~~~

.. image:: https://travis-ci.org/luispedro/imread.png
:target: https://travis-ci.org/luispedro/imread

Python versions 2.6, 2.7 and 3.3 are officially supported.

Python 3.4 should also work (submit a bug report if it does not). Python 3.2
(and earlier versions in the Python 3 series) are officially **not supported**.
