rgb

Color

With a three-dimensional array you get a RGB image.

Here is the code that creates the image:

.. literalinclude:: rgb.py

Note

• the three dimensions are (y-size, x-size, colorchannel)
• the third dimension has to have the size 3
• the three color channels are red [0], green [1], blue [2]
• a 0 in a color channel means that color is inactive
• a 255 in a color channel means that the color is at maximum saturation

Using sliced assignments, you can modify each color channel separately.
