Windows BAT syntax:

Code: Select all

set SRC=1163342704.jpg

%IMG7%magick ^
  -size 1x1 ^
  xc:Red xc:Lime xc:Blue -append ^
  +write mpr:TILE +delete ^
  %SRC% ^
  ( +clone ^
    -tile mpr:TILE -draw "color 0,0 reset" ^
  ) ^
  -evaluate-sequence And ^
  +write 1163_1.jpg ^
  -channel RGB -threshold 25%% +channel ^

This keeps the levels in each channel:


This sets the levels to 0 or 100%:


You can set the threshold anywhere you like.
