I am trying to use imagemagick convert on Ubuntu to crop an image from a .ps
file, and to make this cropped part as a separate image or .png
or .jpg
I tried the following but it didn't work:
convert whatever.ps -crop 105x74mm+30+50 whenever.jpg
This only produced the same file.
I would like to know how can I use it on this file: https://drive.google.com/open?id=15z5tE2c_7vvh7ShDv0oRw7rrG9NUpAO1
