When I scan a paper, there sometimes appears an unnecessary part(not completely white) on the generated file.I want to print the upper 80% part of scanned files(pdf or jpeg).I guess the command$ convert -crop 480x640+0+0 foo2.jpg foo2_croped.jpgmaybe yields a file of bad quality because of recompressing.(But I posted a question concerning this second best way here. )So I think that printing the upper 80% part of the page directly from command line is the best.Is there any technique to print the upper 80% of the page by command line on debian jessie?
