I downloaded some sheet music which was scanned into jpg format at rather low quality, thus yielding a hardly readable print-out. After applying the GEGL operation "brightness-contrast" with values 3.0 and -1.0, resp., the readability of the print-out improved (though still was not really good).
Now I'd like to apply that function to some more images without doing all those steps manually.
There is a command line for gimp, but I failed to find out which parameters I have to feed into it for that function (and never have I used the gimp commandline before...).
Could you show me how to do that? Thanks a lot.
