Parameters:

  • color (string, array_like(3)) – base color

  • colororder (str, dict) – order of color channels of resulting image

The greyscale image is colorized by setting each output pixel to the product of color and the input pixel value.

Example:

>>> from machinevisiontoolbox import Image
>>> img = Image.Read('shark1.png')
>>> img.colorize([1, 0, 0])  # red shark
Image: 500 x 500 (uint8), R:G:B
