create perspective screenshot

README.md

On Twitter, Will McGuan posted a perspective screenshot.

This gist provides few basic steps, using ImageMagick, to produce some similar looking.

Following steps were processed.

• starting with a screenshot of the Rich CLI help in a terminal

• create a perspective view of the screenshot

• add shadow to the perspective

• create a gradient for the background

• combine both images

The script create.sh process all the mentioned steps.

note: The aim was to provide the basic steps and not a fully optimized version of the workflow. Some imagemagick steps could be combined, but were not for clarity.

create.sh

#!/bin/bash

set -o errexit

shadow=02-shadow.png
gradient=03-gradient.png
final=04-final.png

# create perspective view

# add shadow to the perspective view
convert  ${perspective} \( +clone -background black -shadow 80x10+5+10 \) +swap -background none -layers merge +repage  ${shadow}

# create a color gradient for the background
convert -size 1027x850 -define gradient:direction=57 'gradient:rgb(54,200,150)-rgb(20,90,160)' ${gradient}

# combine both images
