# mahotas-imread: Read Image Files

IO with images and numpy arrays.

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](https://luispedro.org/software/mahotas)
for Gaussian filtering):


```python
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 \[[mahotas](https://mahotas.rtfd.io)\] or
packages from others \[[scikit-image](https://scikit-image.org/), for
example\].

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

[Online documentation](https://imread.rtfd.io/)

Python versions 2.6, 2.7, 3.3+ are officially supported.

### Installation/Dependencies

The easiest environment to install mahotas-imread is anaconda, through
[conda-forge](https://conda-forge.github.io). Just use:


```bash
conda config --add channels conda-forge
conda install imread
```

To compile on debian/ubuntu:

```bash
sudo apt-get install libpng12-dev libtiff4-dev libwebp-dev
sudo apt-get install xcftools
```

To compile on Mac:

```bash
sudo port install libpng tiff webp
```

Either way, you can then compile with:

```bash
python setup.py build
```

and install with:

```bash
python setup.py install
```

On Windows, you can also just download a pre-built package from [C.
Gohlke\'s
repository](https://www.lfd.uci.edu/~gohlke/pythonlibs/#imread)

On nix, you can use:

```
nix-env -iA nixpkgs.python3Packages.imread
```

or use the `pkgs.python3Packages.imread` object in your `*.nix` files.
