To report a bug or make a suggestion regarding the &appname; application or this manual, follow the directions in the MATE Feedback Page. User manual for Eye of MATE Image Viewer. Eye of MATE The Eye of MATE Image Viewer application enables you to view single image files, as well as large image collections. You can start &app; in the following ways: Open an image file in Caja. Choose Graphics Image Viewer from the Applications menu. Run eom at the prompt in a terminal such as mate-terminal, or from the Run Application dialog. To close the current &app; window choose File Close, or press CtrlW. &app; 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 &app; supports the following formats for saving: BMP - Windows Bitmap ICO - Windows Icon JPEG - Joint Photographic Experts Group PNG - Portable Network Graphics &app; may be able to open and save other image formats, depending on your system configuration and other installed software. &app; 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, &app; 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. &app; 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. When you start &app;, the following window is displayed:

Shows &app; main window. Contains titlebar, menubar, toolbar, and display area. Menubar contains File, Edit, View, and Help menus.

The &app; window contains the following elements: Menubar The menus on the menubar contain all of the commands that you need to work with images in &app;. Toolbar The toolbar contains a subset of the commands that you can access from the menubar. To show or hide the toolbar, choose ViewToolbar. Display area The display area shows the image file. Statusbar The statusbar provides information about the image. To show or hide the statusbar, choose ViewStatusbar. 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 ViewImage 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 ViewImage Information or press CtrlI. Most actions in &app; can be performed several ways. For example, you can open a file in the following ways: Drag an image file into the &app; 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. To open an image, perform the following steps: Choose FileOpen , or press CtrlO . In the Load Image dialog, select the file you want to open. Click Open. &app; displays the name of the image file in the titlebar of the window. To open another image, choose FileOpen again. &app; opens each image in a new window. To view all images in a folder, perform the following steps: Open one of the images in the folder (see ). Open the image collection by choosing ViewImage 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 ViewFull Screen or press F11. To view them as a slide show, choose ViewSlideshow 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 . 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. You can zoom in or out of the image in the following ways: Use the scroll wheel on your mouse. Scrolling down zooms out; scrolling up zooms in. Choose ViewZoom In or ViewZoom Out. To restore the image to its original size, choose ViewNormal Size. To make the image fit in the window, choose ViewBest 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 if it is too large. 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. To show the image using the entire screen, choose ViewFull 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 &app; automatically switches to the next image in your collection. You can start a slideshow by choosing ViewSlideshow 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 . 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 ). 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 . 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 . To undo a flip or rotate action, choose Edit Undo or press CtrlZ . 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 Caja 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. &app; 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. 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. 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. &app; 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 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:

Shows Eye of MATE Save As dialog when saving multiple images.

The folder in which the images will be saved is specified by the Destination folder drop-down box. Initially the folder is set to the current folder. Select Other... from the drop-down list to open 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 that 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 with underscores 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. Before printing you need to set the page settings you would like to use. To do that choose FilePage 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. To print an image, perform the following steps: Select FilePrint In the Print dialog, select the printer you want to use from the list. Click Print. &app; 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 &app; is currently lacking progress reporting while printing. During that time the user interface might become unresponsive for a short time. 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. &appname;'s default toolbar contains only a basic set of items to keep it simple. But you can modify the toolbar if you prefer a different set. If you want to modify the toolbar you need to open the toolbar editor by going to EditToolbar. The following window will pop up:

Shows Eye of MATE toolbar editor window.

It contains the items that are not in the toolbar and the separator item. You can now edit the toolbar: To add new items to the toolbar, drag them from the toolbar editor to the toolbar. To remove items from the toolbar, drag them from the toolbar to the toolbar editor. To rearrange items on the toolbar, drag them to their new position on the toolbar. When you have finished editing the toolbar, click the Close button in the toolbar editor window. This will close the toolbar editor and make your modified toolbar active. To revert your changes to the toolbar and return to the default layout, perform the following steps: Open the toolbar editor (see ). Click the Reset to Default button. Click the Close button to close the toolbar editor. The toolbar has been reset to the default layout now. Preferences can be changed by going to EditPreferences. You will be able to change the options for image viewing and slide shows. The changes apply to all open windows instantly. 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 &app;. 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 &app; 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 &app; application. 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 ).
