This package allows to map 2D coordinates to different 2D color maps.

The following color maps are available:

  <tr>

The package is based on

## Usage

Basic usage with normalized inputs (i.e., x- and y-coordinates ranging from 0 to 1):

```Python
from pycolormap_2d import ColorMap2DBremm

# Create the color map object.
cmap = ColorMap2DBremm()

# Get the color value.
color = cmap(0.2, 0.6)
```

Optionally, ranges for the input x and y input ranges can be passed during object creation:

```Python
from pycolormap_2d import ColorMap2DBremm

# Create the color map object.
cmap = ColorMap2DBremm(range_x=(-10, 30), range_y=(1, 11))

# Get the color value.
color = cmap(10.0, 8.5)
```
