Arguments:

Description:

Apply specified command on the chosen color channel(s) of each selected images.

You can also make the processing focus on a few particular channels of this colorspace,
by setting color_channels as colorspace_channel (e.g. hsv_h for the hue).
All channel values are considered to be provided in the [0,255] range.

Default values:
