User manual for Eye of GNOME Image Viewer.

## Introduction

The Eye of GNOME Image Viewer application enables you to view single image files, as well as large image collections.

### Starting Image Viewer

You can start Image Viewer in the following ways:

- Open an image file in Nautilus.

- Choose Graphics Image Viewer from the Applications menu.

- Run `eog` at the prompt in a terminal such as gnome-terminal, or from the Run Application dialog.

### Closing Image Viewer

To close the current Image Viewer window choose File Close, or press CtrlW.

### Supported File Types

Image Viewer supports a variety of image file formats. The following image formats can be opened:

- ANI - Animation

- BMP - Windows Bitmap

- GIF - Graphics Interchange Format

- ICO - Windows Icon

- JPEG - Joint Photographic Experts Group

- PCX - PC Paintbrush

- PNG - Portable Network Graphics

- PNM - Portable Anymap from the PPM Toolkit

- RAS - Sun Raster

- SVG - Scalable Vector Graphics

- TGA - Targa

- TIFF - Tagged Image File Format

- WBMP - Wireless Bitmap

- XBM - X Bitmap

- XPM - X Pixmap

Image Viewer supports the following formats for saving:

- BMP - Windows Bitmap

- ICO - Windows Icon

- JPEG - Joint Photographic Experts Group

- PNG - Portable Network Graphics

Image Viewer may be able to open and save other image formats, depending on your system configuration and other installed software.

### Image Viewer Features

Image Viewer has a variety of features to help you view your images. You can zoom in and out or view the image full screen. Regardless of your zoom level, Image Viewer uses a low amount of memory. You can also rotate and flip the image you are viewing.

The collection view allows the viewing and editing of large image collections. In this view image operations can be applied to all selected images at once.

Image Viewer has special support for digital camera pictures and displays EXIF metadata recorded with the image. This feature requires libexif to be installed on your system. All modifications made in JPEG images are lossless. That is, saving rotated and flipped JPEG images will not recompress the image. Beside this all available metadata (like EXIF) will be preserved and updated accordingly.

## Getting Started

When you start Image Viewer, the following window is displayed:

### Image Viewer Start Up Window

Shows Image Viewer main window. Contains titlebar, menubar, toolbar, and display area. Menubar contains File, Edit, View, and Help menus.

The Image Viewer window contains the following elements:

Barra de menuts

  The menus on the menubar contain all of the commands that you need to work with images in Image Viewer.

Barra d'espleches

  The toolbar contains a subset of the commands that you can access from the menubar. To show or hide the toolbar, choose View Toolbar.

Display area

  The display area shows the image file.

Statusbar

  The statusbar provides information about the image. To show or hide the statusbar, choose View Statusbar.

Image Collection

  The image collection shows you all supported images in the current working directory. It shows up once an image has been loaded. To show or hide the collection, choose View Image Collection or press F9.

Image Information Pane

  The image information pane provides further information about the current image, for example EXIF metadata (if available). It shows up after an image has been loaded. To show or hide the image information pane, choose View Image Information or press CtrlI.

Most actions in Image Viewer can be performed several ways. For example, you can open a file in the following ways:

- Drag an image file into the Image Viewer window from another application or window.

- Double-click on an image file in the file manager or other application.

- Choose File Open and select an image file in the Load Image dialog.

- Press CtrlO and select an image file in the Load Image dialog.

## Viewing Images

### Opening an Image

To open an image, perform the following steps:

1. Choose File Open , or press CtrlO .

2. In the Load Image dialog, select the file you want to open.

3. Click Open. Image Viewer displays the name of the image file in the titlebar of the window.

To open another image, choose File Open again. Image Viewer opens each image in a new window.

### Viewing the Images in a Folder

To view all images in a folder, perform the following steps:

1. Open one of the images in the folder (see ).

2. Open the image collection by choosing View Image Collection or pressing F9.

The collection shows thumbnails of all supported images in the folder. You can browse the images by clicking on an image in the collection, by choosing the appropriate option in the Go menu or by pressing AltLeft or AltRight.

To view all of the images in the directory fullscreen, choose View Full Screen or press F11. To view them as a slide show, choose View Slideshow or press F5. To return to the collection view, press the Esc key, or CtrlW. For more information about how to customize the slide show, see .

### Scrolling an Image

To scroll around an image that is larger than the image window or full screen view, you can use the following methods:

- Use the arrow keys on the keyboard.

- Drag the image to move it in the window. (This means you drag the image in the opposite direction you want to scroll in: to scroll down the image, drag it upwards in the window.)

- Use the scrollbars on the window.

### Zooming

You can zoom in or out of the image in the following ways:

- Use the Ctrlscroll wheel on a mouse. Scrolling down zooms out; scrolling up zooms in.

- Choose View Zoom In or View Zoom Out. To restore the image to its original size, choose View Normal Size. To make the image fit in the window, choose View Best Fit.

- Use the zoom buttons in the toolbar. Normal will restore the picture to its original unscaled size. Fit will resize the image so it will fit in the window and adapt the size on window resizing.

- Use the keyboard. To zoom in, Ctrl+ or +. To zoom out, Ctrl- or -. To go back to the normal size, Ctrl0 or 1. To scale the image to fit the window, press F.

When an image is zoomed to fit the window, resizing the window will also change the zoom level, so the image still fits the window.

### Viewing an Image Full Screen/Slideshow

To show the image using the entire screen, choose View Full Screen.

No panels, window frames, or menubars are visible when an image is shown like this. To return to the normal view, press Esc, or F11, or CtrlW.

You can zoom or scroll around the image in the same way as when it is shown in a window, using the mouse or the keyboard.

If you have multiple images in your collection you can press Space or use the right/down cursor keys to advance to the next image. The previous image can be reached by pressing Backspace or using the left/up cursor keys.

In this case you can also use the slideshow mode, where Image Viewer automatically switches to the next image in your collection. You can start a slideshow by choosing View Slideshow or by pressing F5. The slideshow can be paused/continued by pressing P. To stop the slideshow, press the Esc or F5 key, or CtrlW. For more information about how to customize the slide show, see .

## Manipulating Images

All image manipulations apply to all selected images at once. The modifications are done in memory and alter the original files on disk only when the images are saved with the save function (see ).

### Flipping an Image

To flip an image along the horizontal axis of the image, choose Image Flip Horizontal .

To flip an image along the vertical axis of the image, choose Image Flip Vertical .

### Rotating an Image

To rotate an image 90 degrees in a clockwise direction, choose Image Rotate Clockwise .

To rotate an image 90 degrees in an anticlockwise direction, choose Image Rotate Counter Clockwise .

### Undoing an Action

To undo a flip or rotate action, choose Edit Undo or press CtrlZ .

### Deleting an Image

To move an image to the Trash, choose Edit Move to Trash . This moves the file to the Trash folder. Multiple images can also be moved to the trash in the same way: select them all first.

To restore an image from the Trash, open the Trash folder in Nautilus file manager and move the image file to another folder. To delete the image permanently, empty the Trash. To find out more about using the Trash, see the User Guide.

You can also use the Del key to move an image to the Trash, in which case you will be asked for confirmation.

## Saving Images

Image Viewer always tries to choose the save method with least impact to the image data. For example, if an otherwise unmodified image is saved under a different name in the same format, the file is simply copied. If libjpeg is available on the system all JPEG image modifications are done without loss of image information.

### Saving an Image

To save an image, choose File Save . The image will be saved under the same name and file type. Therefore, unmodified images needn't be saved.

### Saving an Image under a Different Name

To save an image under a different name, or convert it to a different file type, choose File Save As .

Specify the filename in the Name field in the Save Image dialog, then click Save. The file is saved in the current folder by default. Image Viewer tries to determine the file type from the given filename suffix. If the image should be saved in another folder or the file type detection failed, expand the dialog by clicking on Browse for other folders. This allows further folder navigation and the specification of the file type from the drop down box.

You can save multiple images at once: see the next section.

### Saving Multiple Images

Saving multiple images at once allows you to convert several images to a different format, or give them similar filenames.

To save multiple images, select the images and choose File Save As . The following window is displayed:

#### Save As dialog for multiple images

Shows Eye of GNOME Salvar e nommar: dialog when saving multiple images.

The folder in which the images will be saved is specified by Destination Folder. Initially the folder is set to to the current folder. The Browse button opens a standard open folder dialog for browsing the filesystem. The resulting filename for each image is specified by Filename Format. The filename schema is constructed by simple characters and special tags. The following special tags are available:

- Filename (%f) - Original filename without the fileformat suffix.

- Counter (%n) - Auto-incremented number (starts at specified counter start).

Everything but these special tags are considered normal text.

The image format is determined by the drop-down box after the schema definition. Select a specific image format or use the as is option to state the the same format as the original file should be used.

The Options section allows to remove all space characters by underscores in the resulting filename if Replace spaces by underscore is checked. The Start counter at spin box determines at which number the counter starts if you use the %n tag for the file format specification.

The File Name Preview section of the dialog shows the resulting file name according to the above settings for an example filename from the selected images.

## Printing Images

### Setting your Page Settings

Before printing you need to set the page settings you would like to use. To do that choose File Page Setup.

In the Page Setup dialog you can now choose paper size and orientation. If possible also select your printer to have the page borders set correctly.

### Printing an Image

To print an image, perform the following steps:

1. Select File Print

2. In the Print dialog, select the printer you want to use from the list.

3. Click Print. Image Viewer starts printing now.

Images that are too large for the page are automatically scaled down to fit the page. Images that are smaller than the page are centered on it.

Please note that Image Viewer is currently lacking progress reporting while printing. During that time the user interface might become unresponsive for a short time.

### Arranging an Image on the Page

Maybe you don't want your image centered or want it scaled down even further. To do that you need to open the Print dialog (see ) and then select the Image Settings tab which offers you the following options:

- The options in the Position section allow you to change the images position on the page.

- It is also possible to position the image on the page by dragging it around in the Preview field.

- The options in the Size section allow you to scale your image to your liking. Scaling is limited by either the image size or by the page size, depending on what condition is met first.

- The Unit option allows you to change the metric unit which is used by the options on the Image Settings tab. When you change this option the other fields values are converted accordingly.

## Preferéncias

Preferences can be changed by going to Edit Preferences. You will be able to change the options for image viewing and slide shows. The changes apply to all open windows instantly.

### Image View

Image Enhancements

  Select the Smooth images when zoomed option to enable image smoothing when you change the image's zoom factor. If you select this option, your images will be smoothed to improve their display quality while viewing them with Image Viewer.

  If you select the Automatic orientation option, your images will be rotated on loading according to their metadata. For example portraits are automatically rotated upright. Note that this function requires a correctly set orientation tag in the image's metadata and thus does not work with all images. The rotation is not saved until you save the rotated image (see ).

Transparent Parts

  Select one of the following options to determine how Image Viewer displays transparent parts of an image:

  - As check pattern

    Displays any transparent parts of the image in a check pattern.

  - As custom color

    Displays any transparent parts of the image in a solid color that you specify. Click on the color selector button to select a color.

  - As background

    Displays any transparent parts of the image in the background color of the Image Viewer application.

### Slideshow

Image Zoom

  Select the Expand images to fit screen option to enlarge images to fit the screen during the slide show. If you do not select this option, images that are smaller than the screen size are not resized to fit the screen.

Sequence

  Select the Loop sequence option to cycle endlessly through the list of images during the slide show. If you do not select this option, the slide show returns to the collection view after the last image is displayed.

  Use the Switch image after ... seconds spin box to specify how long each image is displayed during the slide show. If you set this value to zero, the auto advance function is disabled and only manual browsing is available (see ).
