Steps -

Configuring the script

This script does the transformations to the given image to make it look very nice.

  1. save the .sh file in a new folder of your choice
  2. update output_dir in the script to the new folder you created
  3. set the script as an executable with chmod +x drop-shadow.sh

Installing dependencies

first, you need to install brew
when you have brew, you can run the commands in step 1

  1. brew update && brew install imagemagick && brew cask install copyq (new version below doesn't require copyq)
  2. in your security/privacy accessibility settings make sure you click the + button and add copyq.app (new version below doesn't require copyq)

image

Configuring keyboard maestro

  1. install keyboard maestro
    (make sure you gave it full accessibility permissions just like with copyq)
  2. import the maestro script and update the folder paths to the right folder paths

congrats now when you take screenshots with command+shift+4 and select a portion of your screen, it will be a beautiful screenshot

updated with dynamically generated whitespace based on image dimensions
and don't need to install copyq - using normal copy tool prepackaged with OS X
