Usage

usage: img-ditto [-h] [-o OUTPUT] [-s STRENGTH] [-c COLORSPACE]
                 from_im to [to ...]

Transfer the style from one image to another using histogram distributions

positional arguments:
  from_im               The image who's style you want to use
  to                    The image(s) you want to transfer the style to

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        The suffix to append to the output files
  -s STRENGTH, --strength STRENGTH
                        The strength of the transfer, should be between 0.0
                        and 1.0. Defaults to 0.8
  -c COLORSPACE, --colorspace COLORSPACE
                        The colorspace to use for the transformation.
                        Currently supported are rgb, hsv, and lab. Defaults to
