pycolormap-2d 1.0.0

A Python package mapping 2D coordinates to colors based on different 2D color maps.

Colormap 2D Python Package

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

The following color maps are available:

ColorMap2DBremm	ColorMap2DCubeDiagonal	ColorMap2DSchumann
ColorMap2DSteiger	ColorMap2DTeuling2	ColorMap2DZiegler

The package is based on

M. Steiger, J. Bernard, S. Thum, S. Mittelstädt, M. Hutter, D. A. Keim, and J. Kohlhammer, “Explorative Analysis of 2D Color Maps,” in International Conferences in Central Europe on Computer Graphics, Visualization and Computer Vision, 2015, vol. 23, pp. 151–160.**

For a JavaScript implementation, refer to the Color2D project by Dominik Jäckle.

Example

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

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:

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)
