10.1.4. Electric Eyes
If you want a quick and simple way of viewing one file, Electric Eyes may be for you. To start
Electric Eyes from a GNOME desktop, choose Main Menu => Programs => Graphics => Electric
Eyes. For KDE users, choose Start Application => Programs => Graphics => Electric Eyes. You
can also type ee at a shell prompt. Right-click the Electric Eyes logo to open the pop-up menu and
load an image. Right-click on displayed images to configure certain aspects of the image as well as
the Electric Eyes environment.
For example, to open the Editing Controls, choose View => Show/Hide Edit Window, and the
Editing Control dialog box will pop up, allowing you to change brightness and color saturation
levels on the image.
Figure 10-8. Editing Options in Electric Eyes
Buttons along the bottom of the Editing Control window let you zoom in and out of an image in-
crementally by percentage, fit the image to the screen, and even turn the image 90% clockwise, or
invert (flip) the image horizontally or vertically. Electric Eyes is an ideal choice for viewing and
manipulating single images.
