Misc

1. imagemagick is wonderful! Let's say we have img1.png img2.png. This command compares two images and highlight differences into diff.png:

compare -highlight-color 'rgba(255, 255, 0, 0.5)' -lowlight-color 'rgba(255, 255, 255, 0.3)' img1.png img2.png diff.png

This give number of different pixels between two:

convert img1.png img2.png -compose Difference -composite -format '%[fx:mean*100]' info:

2. terminal-notifier Get alert by using command line:

/Applications/terminal-notifier.app/Contents/MacOS/terminal-notifier -message 'Hello' -title 'CI'
