Are you trying to capture a screenshot of a web page? You could screen capture the web page manually after loading it on a web browser. However, if the layout of the web page does not fit into the screen of your computer, the screenshot wouldn't cover the whole page, but only part of it.
In Linux, there is a GNOME application called
gnome-web-photo that can generate a full-size screenshot or thumbnail of a website or any URL.
In this tutorial, I will describe how to take a full-length screenshot of a web page by using
gnome-web-photo is a GNOME application, you need to use a desktop environment in Linux.
$ sudo apt-get install gnome-web-photo
$ sudo yum install gnome-web-photo
If you are a CentOS or RedHat user, be aware that
gnome-web-photo depends on GTK+ 3.0. This means that
gnome-web-photo is not compatible with GNOME 2, which is shipped with CentOS/RHEL 6 and higher.
To take a screenshot of a web page without scrolling down the page, use the following command:
$ gnome-web-photo -t 0 --mode=photo http://www.washingtonpost.com output.png
-t option specifies the timeout value (in seconds) for screenshot generation.
-t 0 means that timeout is disabled.
gnome-web-photo, you can also generate a small thumbnail of a webpage as follows. Optionally, you can specify thumbnail size by using
-s option. The default thumbnail size is 256x256.
$ gnome-web-photo -t 0 -s 128 --mode=thumbnail http://www.washingtonpost.com output.png
If you want to save a screenshot of a website as a multi-page PDF, so that you can print it out later, you can use the following command.
$ gnome-web-photo -t 0 --mode=print http://www.washingtonpost.com output.pdf
