# cmapy

Use Matplotlib colormaps with OpenCV in Python.

Matplotlib provides a lot of [nice colormaps](https://matplotlib.org/tutorials/colors/colormaps.html). Cmapy exposes these colormaps as lists of colors that can be used with OpenCV to colorize images or for other drawing tasks in Python.

See all of the available colormaps as of Matplotlib 2.2.3 in this [all colormaps example](https://gitlab.com/cvejarano-oss/cmapy/blob/master/docs/colorize_all_examples.md).

## Requirements

* Python 2.7 or 3.
* Matplotlib.
* OpenCV >= 3.3.0 (to use cv2.applyColorMap()).

## Installation

Python 2.7, with pip:

```bash
pip install cmapy
```

Python 3.x, with pip:

```bash
pip3 install cmapy
```

Or, in a Conda environment:

```bash
conda install -c conda-forge cmapy 
```

## How to use

### Colorize images

Colorize means to apply a colormap to an image. This is done by getting the colormap
with cmapy.cmap() and then applying cv2.applyColorMap(), like this:

```python
img_colorized = cv2.applyColorMap(img, cmapy.cmap('viridis'))
```

Alternatively, you can use cmapy.colorize() directly:

```python
img_colorized = cmapy.colorize(img, 'viridis')
```

See the full [colorize example](https://gitlab.com/cvejarano-oss/cmapy/blob/master/examples/colorize.py).

### Draw with colors

Use the cmapy.color() function and an index between 0 and 255 to get a color 
from a colormap. Cmapy.color() returns a list of BGR (or RGB) values that can be
used with OpenCV drawing functions.

```python
# Get color in BGR order (default) by index.
bgr_color = cmapy.color('viridis', 127)

# Get color in RGB order with a float value.
rgb_color = cmapy.color('viridis', 0.5, rgb_order=True)
```
