Capturing Screen Images

Capturing Screen Images

Although you're working at the command line rather than a swish GUI, you can still grab images from your graphical desktop through the import command, and that's exactly what we did to capture the images for this book.

First, we ran xhost + on the remote computer to allow another computer access to the X server on the remote machine; the command to take the screenshot is run on our local machine like this:

$ import -window root -display 192.168.2.4:0 12fig07.jpg

This utility made a difficult task easy because the publisher required the screenshots be done from an 800?600 screen (too small to comfortably work in) to accommodate its printing and production equipment.

We could also have used the classic UNIX tool xwd to take screenshots. The command would have looked similar to that of import:

$ xwd -root -display 192.168.2.4:0 -out 12fig07.jpg
