Tips

• You can call web-screenshot with the URL only, such as web-screenshot -u github.com.
• The program will append http:// to your URL and save the output file as github.com.png.
• If width or height are 0, a Full Page screenshot is taken.
• The base viewport is 1920x1080.
• After the ScreenShot is taken, the borders can be cropped using --crop. Powered by Jimp.
• You can screenshot just a rectangle (or clip) of a webpage by providing x, y, w and h, such as

web-screenshot -u https://google.com -x 700 -y 190 -w 700 -h 180 -o google_logo.png --crop

Coordinates are approximate and you can either use a tool to measure the pixels or trial and error.

The command outputs the image:

google_logo.png

Happy Screenshotting!
