Thanks a lot Frediz,
Actually I've been palying quite a moment with your fantastic tool!
It does amazing things so quickly!!
(btw, I doubt if such a tool could ever get a gui...)
It seems that your initial instructions about the mhs filter
(the most impressive feature which allows to split horizontally the comic strip) could be outdated (maybe a previous version?). After severals tests, I didn't find the way to pass parameters to mhs concerning the number of pictures in which the original must be split.
But I found that you can set the sensitivity threshold to autosplit the picture (probably based on white balance).
This is the instruction that is given with
cpu -f mhs=help
Splits image horizontally at blank lines.
m : min white : all pixels of line should have higher value to be a split line
s : min size region : the splitted region won't be less than that (Default=140)
I get good reults in my tests with a value of 15-30. So, it gives something like this:
cpu -o out -f mhs=20 pic1.jpg
One has to play with the value of the parameter to optimize the result, although some failures needing fine tuning are unavoidable.
If you want a rotated, greyscale, autocropped, horizontally autosplitted comic, it goes like this:
cpu -o out -f r,g,a,mhs=20 pic1.jpg2.
My only small deception is the -f s (autosplit) filter. Unlike mhs for horizontal splitting, it splits vertically in equal parts, with no autodetection logic. If one wants to have "intelligent" vertical autosplitting, the solution is to aplly mhs after a rotation and to do the counter rotation back after...
Anyway, it's a Great Tool
