How to take a webpage screenshot at terminal window

The scenario is to run the program inside of Ubuntu VPS.  Input a URL the program will output the jpg file.

The solution is to use wkhtmltoimage, which is a part of wkhtmtopdf.

I used to use the old version wkhtmltopdf v0.12.3. Now it is not working anymore due to some reason I don’t know.

But the wkhtmltopdf v0.12.5  is OK.

The OS is Ubuntu 18.04.

Then I install wkhtmltopdf with the following command

sudo apt-get install -y software-properties-common
sudo apt-add-repository -y "deb http://security.ubuntu.com/ubuntu xenial-security main" 
sudo apt-get -yq update
sudo apt-get install -y libxrender1 libfontconfig1 libx11-dev libjpeg62 libxtst6 fontconfig xfonts-75dpi xfonts-base libpng12-0 libjpeg-turbo8
wget "https://downloads.wkhtmltopdf.org/0.12/0.12.5/wkhtmltox_0.12.5-1.xenial_amd64.deb" 
sudo dpkg -i wkhtmltox_0.12.5-1.xenial_amd64.deb 
sudo apt-get -f install

After installation, run the command to show the help of the program.

Now I am going to render an image from the most famous web site.
The URL is https://www.google.com
Run the following command to generate the screenshot.

wkhtmltoimage --javascript-delay 3500 --height 768 --quality 64 "https://www.google.com" /home/davidyin/google.jpg

Let’s see the result.

Later, I did it with Youtube.
