Potential test case: Convert RGB image to CMY

[Romain-Laine]

Here's a snippet that converts an RGB image into a CMY (Cyan Magenta Yellow) image.

def convert_rgb_to_cmy(rgb_image: np.ndarray) --> np.ndarray:
    """
    Convert and RGB image into a CMY image
    Arguments:
    - rgb_image: input RGB image of shape [width, height, 3]
    Output:
    - CMY image
    """
    cmy_image = np.zeros((imgs.shape[0], imgs.shape[1], 3))
    cmy_image[:, :, 0] = rgb_image[:, :, 0] + rgb_image[:, :, 2]
    cmy_image[:, :, 1] = rgb_image[:, :, 0] + rgb_image[:, :, 1]
    cmy_image[:, :, 2] = rgb_image[:, :, 2] + rgb_image[:, :, 1]

    return np.clip(cmy_image, 0, 1)

Hi @Romain-Laine ,

that's a good one! Would you mind sending a Pull-request with this? Also consider rewriting the docstring a bit so that it's more like a sentence a human has written, and less technically formatted.

Thanks!

Best,
Robert
