Read the input first, then put the settings, then the command. Shave does both top and bottom. You want -chop.

Code: Select all

See https://www.imagemagick.org/script/comm ... .php#shave and https://www.imagemagick.org/script/comm ... s.php#chop

You need 0x50 to remove from top/bottom but not left/right. Setting like "-gravity" for operations must come before those operations, not after.

"-shave" is not sensitive to "-gravity". "-chop" is, so:

Code: Select all
