Starting Eye of Gnome opens an image window, shown in Figure 1.
To load an image into the image window, simply click the Open button on the main toolbar. A standard file dialog will then open to allow you to select an image file. Eye of Gnome will automatically detect the type of image being opened.
You can also open images by dragging them from another program and dropping them into an image window. For example, you can select a number of image files in the file manager and drag them to Eye of Gnome.
Eye of Gnome supports the following image file formats:
BMP (Windows Bitmap)
GIF (Graphics Interchange Format)
ICO (Windows Icon)
JPEG (Joint Photographic Experts Group)
PNG (Portable Network Graphics)
PNM (Portable Anymap from the PPM Toolkit)
RAS (Sun Raster file)
TÏFF (Tagged Image File Format)
XPM (X Pixmap)

If the file you select is of a type that Eye of Gnome does not recognize, a dialog will appear to warn you that Eye of Gnome was unable to process the selected file. On a side note, the type of a file can be found using the Unix file command. |
After an image is loaded into the viewer, you can make use of the buttons in the toolbar, shown in Figure 2:
Opens a new image. Depending on the preferences settings, the new image will substitute the current image in the window or a new window will be created for it.
Closes the corresponding image window. If this is the last open window, the program will exit.
Zooms into the image, that is, it makes the image appear larger.
Zooms out of the image, that is, it makes the image appear smaller.
Sets the zoom factor to 1:1, that is, pixels on the screen will match the pixels on the original image.
Resizes the image so that it fills the image window.
One of the main features of Eye of Gnome as an image viewer is that it lets you view very large images easily. You can do this by changing the zoom factor at which images are displayed and by scrolling around the area of an image.
Eye of Gnome lets you change the zoom factor of an image in several ways:
If you have a wheel mouse, you can simply use the wheel to quickly adjust the zoom factor.
You can use the toolbar buttons as shown in Figure 2 in the section called Image Windows.
You can press the + (plus) and - (minus) keys to increase and decrease the zoom factor, respectively.

You can press 1 to set the zoom factor to 1:1, or you can press F to fit the image to the window size.
You can use the zooming commands in the View menu.
In addition, you can use the 1:1 or Fit buttons in the toolbar to go back to the original image's size or to make it fill the window, respectively.
If an image is zoomed so that it does not fit in the window, you can scroll it in several ways:
You can simply click on the image and drag it around.
You can use the scrollbars with the mouse.
You can use the arrow keys to pan the image.
A wheel mouse is the most convenient way to navigate around a large image, since you can zoom and drag the image using only the mouse. If you prefer the keyboard, you can use it without having to use the mouse as well.
The menu bar located at the top of image windows provides the following commands.
Create New Window . Creates a new, empty image window. You can open any number of windows and load images into them.
