Orientation of -r in doc swaped

[Jan-NiklasB]

Hey,

pretty cool project, but the speed could be increased :D (multi threading?)

Anyways, in the tutorials and the Doc the orientation of the -r arg are switched around leading to inlier issues.
As correctly shown if you use the -h arg, the right orientation in the Doc should be:

width x height + right (x) + top (y)

and not "Use the extracted position and size while invoking extractmpl using a standard geometry specification: WIDTHxHEIGHT+TOP+LEFT:"
