Darken with Opacity Effects for Single Image

[mjamal]

Hello Team,

Can anyone please let me know how can I use the layers as "DARKEN" and Opacity as 30% for any image from Imagick functions?
NOTE: Need to change the above two effects for a single image only.

Please see the attached image from photoshop for reference.

I don't use PS, but it's probably something like this (Windows BAT syntax):

Code: Select all

convert ^
  inA.png ^
  ( inB.png -channel A -evaluate Multiply 0.3 +channel ) ^
  -compose Darken -composite ^
