    .Sh DESCRIPTION
    .Nm
    
    is a mode-based image viewer.  It is especially aimed at commandline users who
    need a fast image viewer without huge GUI dependencies, though it can also be
    started by
    
    file managers to view an image.
    
    supports filelists, various image sorting modes, image captions and more.
    Control happens via keyboard shortcuts; the mouse can also be used to control
    it, but is only required for very few actions.
    
    .Nm
    is based on various modes, which are selected at startup by comandline
    options.
    .Pp
    Slideshow mode is the default.  It opens one window and displays the first
    image in it, the keyboard and mouse can be used to change slides
    .Pq images .
    In slideshow mode, images can be deleted either from the filelist or from the
    disk, the new filelist can then be saved to the disk and reopened at a later
    time.
    .Pp
    
    Montage mode forms a montage from the filelist.  The resulting image can be
    viewed or saved, and its size can be limited by height, width or both.
    .Pp
    Collage mode is very similar to montage mode, except the images are distributed
    randomly and may overlap each other.
    .Pp
    Index mode forms an index print from the filelist.  Image thumbnails are shown
    along with the filename, filesize and pixel size, printed using a truetype
    font of your choice.  The resulting image can be viewed or saved, and its size
    can be limited by height, width or both.
    .Pp
    Thumbnail mode is like index mode, but the mini-images are clickable and open
    the selected image in a new window.
    .Pp
    Multiwindow mode shows images in multiple windows, instead of as a slideshow
    in one window.  Don't use with a large filelist ;)
    .Pp
    List mode doesn't display images.  Outputs an
    .Cm ls - No style
    listing of the files in the filelist, including image info such as size,
    pixels, type, etc.  Customlist mode will display whatever image info you want,
    in the format you choose.
    .Pp
    .Nm
    
    can also list either all the loadable files in a filelist or all the
    
    unloadable files.  Useful for preening a directory.
    .
    
    .Sh OPTIONS
    .Bl -tag -width indent
    
    .It Cm -A , --action Oo Ar flag Oc Ns Ar action
    
    Specify a string as an action to perform on the image.  In slideshow or
    multiwindow modes, the action will be run when the enter key is pressed, in
    list mode, the action will be run for each file listed.  In
    loadables/unloadables mode, the action will be run for each
    loadable/unloadable file, respectively.
    
    .Pp
    If
    .Ar flag
    is
    .Qq \&; ,
    .Nm
    will not switch to the next image after executing the action.
    .Pp
    
    The action will be executed by /bin/sh.  Use format specifiers to refer to
    image info.  See
    .Sx FORMAT SPECIFIERS
    for examples.  E.g.
    .Qq feh -A "mv ~/images/%n" * .
    In slideshow mode, the next image will be shown after running the action, in
    multiwindow mode, the window will be closed.
    
    .It Cm --action1 No .. Cm --action9
    Extra actions which can be set and triggered using the appropiate number key.
    
    .It Cm -Z , --auto-zoom
    Zoom pictures to screen size in fullscreen
    .Pq affected by Cm --stretch No and Cm --ignore-aspect .
    
    .It Cm -x , --borderless
    Create borderless windows.
    
    .It Cm -Q , --builtin
    Use builtin HTTP client to grab remote files instead of
    .Xr wget 1 .
    
    .It Cm -P , --cache-thumbnails
    
    Enable (experimental) thumbnail caching in
    .Pa ~/.thumbnails .
    
    Only works with thumbnails <= 256x256 pixels.
    
    .It Cm -K , --caption-path Ar path
    
    Path to directory containing image captions.  This turns on caption viewing,
    and if captions are found in
    .Ar path ,
    which is relative to the directory of each image, they are overlayed on the
    displayed image.  E.g. with caption path
    .Qq captions/ ,
    and viewing image
    .Qq images/foo.jpg ,
    the caption will be looked for in
    .Qq images/captions/foo.jpg.txt .
    
    .It Cm -c , --collage
    Enable collage mode.  Collage mode is very similar to montage mode, except
    the images are distributed randomly.
    When using collage mode, you should also specify
    .Cm --limit-width
    and
    .Cm --limit-height .
    
    .It Cm -L , --customlist Ar format
    Use
    .Ar format
    .Pq printf-like string containing image info specifiers
    for list output.  See
    .Sx FORMAT SPECIFIERS .
    
    .It Cm --cycle-once
    Exit feh after one loop through the slideshow.
    
    .It Cm -G , --draw-actions
    
    Draw the defined actions and what they do at the top-left of the image.
    
    .It Cm -d , --draw-filename
    Draw the filename at the top-left of the image.
    
    .It Cm -f , --filelist Ar file
    
    This option is similar to the playlists used by music software.  If
    
    .Ar file
    exists, it will be read for a list of files to load, in the order they appear.
    The format is a list of image filenames, absolute or relative to the current
    
    directory, one filename per line.  If
    
    .Ar file
    doesn't exist, it will be created from the internal filelist at the end of a
    viewing session.  This is best used to store the results of complex sorts
    .Pq Cm -Spixels No for example
    for later viewing.  Any changes to the internal filelist
    .Pq such as deleting a file or it being pruned for being unloadable
    will be saved to
    .Ar file
    when
    .Nm
    exits.  You can add files to filelists by specifying them on the commandline
    when also specifying the list.
    
    .It Cm -e , --font Ar font
    Set global font.  Should be a truetype font, resident in the current directory
    or the font directory, and should be defined in the form fontname/points, like
    .Qq myfont/12 .
    
    .It Cm -C , --fontpath Ar path
    Specify
    .Ar path
    as extra directory in which to search for fonts; can be used multiple times to
    add multiple paths.
    
    .It Cm -I , --fullindex
    Same as Index mode, but you also get image size and dimensions printed
    below each thumbnail.
    
    Make the window fullscreen.
    
    .It Cm -g , --geometry Ar width No x Ar height
    Limit (and don't change) the window size.  Takes an X-style geometry
    .Ar string
    like 640x480.
    Note that larger images will be zoomed out to fit but you can see them at 1:1
    by clicking the zoom button.
    
    .It Cm -h , --help
    display help output and exit.
    
    .It Cm -Y , --hide-pointer
    
    Hide the pointer
    .Pq useful for slideshows etc .
    
    .It Cm -B , --image-bg Ar style
    Use style as background for transparent image parts and the like.
    Accepted values: white, black, default.
    
    .It Cm -i , --index
    Enable Index mode.  Index mode is similar to montage mode, and accepts the
    same options.  It creates an index print of thumbails, printing the image
    name beneath each thumbnail.  Index mode enables certain other options, see
    .Sx INDEX MODE OPTIONS .
    
    .It Cm --index-dim Ar bool
    Toggle showing image dimensions in thumbnail/index mode.
    
    .It Cm --index-name Ar bool
    Toggle showing the filename in thumbnail/index mode.

    .It Cm --info Ar commandline
    Execute
    .Ar commandline
    
    and display its output in the bottom left corner of the image.  Can be used to
    
    Birte Kristina Friesel's avatar
    Birte Kristina Friesel committed
    display e.g. image dimensions or EXIF information.  Supports
    .Sx FORMAT SPECIFIERS .
    .
    
    .It Cm -k , --keep-http
    When viewing files using HTTP,
    .Nm
    normally deletes the local copies after viewing, or, if caching, on exit.
    This option prevents this so that you get to keep the local copies.
    They will be in
    .Pa /tmp
    with
    .Qq Nm
    in the name.
    
    .It Cm -l , --list
    
    Don't display images.  Analyse them and display an
    
    .Xr ls 1 - No style
    listing.  Useful in scripts to hunt out images of a certain
    size/resolution/type etc.
    
    .It Cm -U , --loadable
    Don't display images.  Just print out their names if imlib2 can successfully
    load them.
    
    .It Cm -) , --menu-bg Ar file
    Use
    
    as background image in menus.
    
    .It Cm -M , --menu-font Ar font
    Use
    .Ar font
    .Pq truetype, with size, like Qq yudit/12
    as menu font.
    
    .It Cm --menu-style Ar file
    Read
    .Ar file
    to determine menu style.
    
    .It Cm -m , --montage
    Enable montage mode.  Montage mode creates a new image consisting of a grid of
    thumbnails of the images in the filelist.  When montage mode is selected,
    certain other options become available.  See
    .Sx MONTAGE MODE OPTIONS .
    
    .It Cm -w , --multiwindow
    Disable slideshow mode.  With this setting, instead of opening multiple files
    in slideshow mode, multiple windows will be opened; one per file.
    
    .It Cm --no-jump-on-resort
    Don't jump to the first image after resorting the filelist.
    
    .It Cm -N , --no-menus
    
    Don't load or show any menus.
    
    .It Cm --no-screen-clip
    By default, window sizes are limited to the screen size.  With this option,
    windows will have the size of the image inside them.  Note that they may
    become very large this way, making them unmanageable in certain window
    managers.
    
    .It Cm --no-xinerama
    Disable Xinerama support.  Only makes sense when you have Xinerama support
    compiled in.
    
    .It Cm -j , --output-dir Ar directory
    Save files to
    .Ar directory
    .Pq only useful with -k
    
    .It Cm -p , --preload
    Preload images.  This doesn't mean hold them in RAM, it means run through
    them and eliminate unloadable images first.  Otherwise they will be removed
    as you flick through.  This also analyses the images to get data for use in
    sorting, such as pixel size, type etc.  A preload run will be automatically
    performed if you specify one of these sort modes.
    
    .It Cm -q , --quiet
    Don't report non-fatal errors for failed loads.  Verbose and quiet modes are
    not mutually exclusive, the first controls informational messages, the second
    only errors.
    
    .It Cm -z , --randomize
    When viewing multiple files in a slideshow, randomize the file list before
    displaying.
    
    .It Cm -_ , --rcfile Ar file
    Use
    .Ar file
    to parse themes and options from, instead of the default
    .Pa ~/.fehrc , /etc/fehrc
    files.
    
    .It Cm -r , --recursive
    Recursively expand any directories in the commandline arguments
    to the content of those directories, all the way down to the bottom level.
    
    .It Cm -R , --reload Ar int
    Reload images after
    .Ar int
    seconds.  Mainly useful when viewing webcams via http.
    
    .It Cm -n , --reverse
    Reverse the sort order.  Use this to invert the order of the filelist.
    E.g. to sort in reverse width order, use
    .Cm -nSwidth .
    
    .It Cm -. , --scale-down
    When not in fullscreen: Scale images to screen size if they are too big.
    
    .It Cm -D , --slideshow-delay Ar float
    For slideshow mode, wait
    .Ar float
    seconds between automatically changing slides.  Useful for presentations.
    
    Specify a negative number to set the delay
    .Pq which will then be Ar float No * (-1) ,
    but start feh in paused mode.
    
    .It Cm -S , --sort Ar sort_type
    The file list may be sorted according to image parameters.  Allowed sort
    types are: name, filename, width, height, pixels, size, format.  For sort
    modes other than name or filename, a preload run will be necessary,
    causing a delay proportional to the number of images in the list.
    
    .It Cm -| , --start-at Ar filename
    Start the filelist at
    .Ar filename .
    See
    .Sx USAGE EXAMPLES .
    
    .It Cm -T , --theme Ar theme
    Load options from config file with name
    .Ar theme
    - see
    .Sx CONFIG FILE SYNTAX
    for more info.  Note that options from the theme file always override
    commandline options.
    
    .It Cm -t , --thumbnails
    Same as Index mode, but the thumbnails are clickable image launchers.
    
    does not affect the thumbnail window. It does, however, work for the image
    windows launched from thumbnail mode.
    
    .It Cm -~ , --thumb-title Ar string
    Set
    .Ar title
    for windows opened from thumbnail mode.  See also
    .Sx FORMAT SPECIFIERS .
    
    .It Cm -^ , --title Ar title
    
    Set window title.  Applies to all windows except those opened from thumbnail
    mode.  See
    
    .Sx FORMAT SPECIFIERS
    
    .It Cm -u , --unloadable
    Don't display images.  Just print out their names if imlib2 can NOT

    .Sh MONTAGE MODE OPTIONS
    
    .
    These additional options can be used for montage, collage and (partially)
    thumbnail modes.
    .
    
    .Bl -tag -width indent
    
    .It Cm -a , --alpha Ar int
    When drawing thumbnails onto the background, set their transparency level to
    .Ar int
    .Pq 0 - 255 .
    
    .It Cm -b , --bg Ar file No | Cm trans
    Use
    .Ar file
    as background for your montage.  With this option specified, the montage size
    will default to the size of
    .Ar file
    if no size restrictions were specified.  Alternatively, if
    .Ar file
    is
    .Qq trans ,
    the background will be made transparent.
    
    .It Cm -X , --ignore-aspect
    
    By default, the montage thumbnails will retain their aspect ratios, while
    
    fitting into thumb-width/-height.  This options forces them to be the size set
    by
    .Cm --thumb-width No and Cm --thumb-height .
    This will prevent any empty space in the final montage.
    
    .It Cm -H , --limit-height Ar pixels
    Limit the height of the montage.  These options can be used together to define
    the image size exactly, or separately.  If only one is specified, the other is
    calculated from the number of files specified and the size of the thumbnails.
    The default is to limit width to 800 pixels and calculate the height as
    necessary.
    
    .It Cm -W , --limit-width Ar pixels
    Limit the width of the montage.
    
    .It Cm -o , --output Ar file
    Save the created montage to
    .Ar file .
    
    .It Cm -O , --output-only Ar file
    Just save the created montage to
    .Ar file
    without displaying it.
    
    .It Cm -s , --stretch
    Normally, if an image is smaller than the specified thumbnail size, it will
    not be enlarged.  If this option is set, the image will be scaled up to fit
    the thumnail size.  Aspect ratio will be maintained unles
    .Cm --ignore-aspect
    is specified.
    
    .It Cm -E , --thumb-height Ar pixels
    Set thumbnail height.
    
    .It Cm -y , --thumb-width Ar pixels
    Set thumbnail width.
    
    .It Cm -J , --thumb-redraw Ar n
    
    Only relevant for
    .Cm --thumbnails :
    Redraw thumbnail window every
    .Ar n
    images.  In
    .Nm
    <= 1.5, the thumbnail image used to be redrawn after every computed thumbnail
    .Pq so, it updated immediately .
    However, since the redrawing takes quite long
    .Pq especially for thumbnail mode on a large filelist ,
    this turned out to be a major performance penalty.
    As a workaround, the thumbnail image is redrawn every 10th image now by
    default. Set
    .Ar n No = 1
    to get the old behaviour,
    .Ar n No = 0
    will only redraw once all thumbnails are loaded.
    
    .El
    .
    .Sh INDEX MODE OPTIONS
    .Bl -tag -width indent
    
    .It Cm -@ , --title-font Ar font
    Set font to print a title on the index, if no font is specified, no title will
    be printed.
    .El
    .
    
    .Sh BACKGROUND SETTING
    .Nm
    can also be used as a background setter.  It will store the command line
    necessary to set the background in
    .Pa ~/.fehbg ,
    so to have your background restored everytime you start X, you can add
    .Qq `cat ~/.fehbg`
    to your X startup script
    .Pq like Pa ~/.xinitrc .
    .Pp
    The following options control how exactly the background is set.  Each of them
    takes exactly one file as argument.
    .Bl -tag -width indent
    .
    .It Cm --bg-center
    Center the file on the background.  If it is too small, it will be surrounded
    by a black border
    .
    .It Cm --bg-fill
    Like
    .Cm --bg-scale ,
    but preserves aspect ratio by zooming the image until it fits.  Either a
    horizontal or a vertical part of the image will be cut off
    .
    
    .It Cm --bg-max
    Like
    .Cm --bg-fill ,
    but scale the image to the maximum size that fits the screen with black borders on one side.
    .
    
    .It Cm --bg-scale
    Fit the file into the background without repeating it, cutting off stuff or
    using borders.  But the aspect ratio is not preserved either
    .
    .It Cm --bg-tile
    Tile
    .Pq repeat
    the image in case it is too small for the screen
    .

    .Sh CONFIG FILE SYNTAX
    The config file allows the naming of option groups, called themes.
    
    .Pa ~/.fehrc No or Pa /etc/fehrc
    exist,
    .Nm
    will look in them for name/options pairs.
    If neither of them exist,
    .Nm
    will create a default one in
    .Pa ~/.fehrc .
    .Pp
    It takes entries of the form
    .Qq Ar theme options ... ,
    where
    .Ar theme
    is the name of the entry and
    .Ar options
    are the options which will be applied when the theme is used.
    .Pp
    An example entry would be
    .Qq imagemap -rVq --thumb-width 40 --thumb-height 30 .
    .Pp
    You cane use this theme in two ways.  Either call
    .Qo
    .Nm
    -Timagemap *.jpg
    .Qc
    or create a symbolic link to
    .Nm
    with the name of the theme you want it to use.  So from the example above:
    .Qo
    ln -s `which
    .Nm
    ` ~/bin/imagemap
    .Qc .
    Now just run
    .Qq imagemap *.jpg
    to use these options.
    .Pp
    
    Note that you can split a theme over several lines by placing a backslash at
    the end of a line, like in the shell.
    .Pp
    
    You can combine these themes with commandline options.  An example .fehrc is
    provided with a couple of cool example themes.

    .Sh MOUSE ACTIONS
    When viewing an image, by default mouse button 1 pans
    .Pq moves the image around
    or, when only clicked, moves to the next image
    .Pq slideshow mode only ;
    button 2 zooms
    .Po click and drag left->right to zoom in, right->left to zoom out, click once
    to restore zoom to 100%
    .Pc ;
    and mouse button 3 opens the menu.
    .Pp
    CTRL+Button 1 blurs or sharpens the image
    .Pq drag left to blur, right to sharpen ;
    CTRL+Button 2 rotates the image around the center point.
    .Pp
    A note about pan and zoom modes:
    In pan mode, if you reach a window border but haven't yet panned to the end of
    the image,
    .Nm
    will warp your cursor to the opposite border so you can continue panning.
    .Pp
    When clicking the zoom button and immediately releasing it, the image will be
    back at 100% zoom.  When clicking it and moving the mouse while holding the
    
    button down, the zoom will be continued at the previous zoom level.  The zoom
    will always happen so that the pixel on which you entered the zoom mode
    remains stationary.  So, to enlarge a specific part of an image, click the
    zoom button on that part.
    
    .Sh SIGNALS
    In slideshow mode,
    .Nm
    handles the following signals:
    .Bl -tag -width indent
    
    .Sh USAGE EXAMPLES
    Here are some examples of useful option combinations
    .Bl -tag -width indent
    
    .
    .It feh /opt/images
    Show all images in /opt/images
    .
    
    .It feh -r /opt/images
    
    Recursively show all images found in /opt/images and subdirectories
    .
    .It feh -rSfilename /opt/images
    Same as above, but sort by filename. By default, feh will show files in the
    order it finds them on the hard disk, which is usually somewhat random.
    .
    .It feh -t -Sfilename -E 128 -y 128 -W 1024 /opt/images
    Show 128x128 pixel thumbnails, limit window width to 1024 pixels.
    .
    .It feh -t -Sfilename -E 128 -y 128 -W 1024 -P -C /usr/share/fonts/truetype/ttf-dejavu/ -e DejaVuSans/8 /opt/images
    Same as above, but enable thumbnail caching in ~/.thumbnails and use a smaller
    font.
    .
    
    .It feh -irFarial/14 -O index.jpg /opt/images
    
    Make an index print of /opt/images and all directories below it, using 14 point
    
    Arial to write the image info under each thumbnail.  Save the image as
    index.jpg and don't display it, just exit.  Note that this even works without
    a running X server
    
    .It feh --unloadable -r /opt/images
    Print all unloadable images in /opt/images, recursively
    
    .It feh -w /opt/images/holidays
    Open each image in /opt/images/holidays in its own window
    
    .It feh -FD5 -Sname /opt/images/presentation
    Show the images in .../presentation, sorted by name, in fullscreen,
    automatically change to the next image after 5 seconds
    
    .It feh -rSwidth -A Qo mv '%f' ~/images/'%n' Qc /opt/images
    View all images in /opt/images and below, sorted by width, move an image to
    
    ~/image/image_name when enter is pressed
    
    .It feh --start-at ./foo.jpg \&.
    View all images in the current directory, starting with foo.jpg.  All other
    images are still in the slideshow and can be viewed normally
    
    .It feh --start-at foo.jpg *
    Same as above
    
    .
    .It feh --info \&"exifgrep '\&(Model\&|DateTimeOriginal\&|FNumber\&|ISO\&|Flash\&)' '%f' \&| cut -d \&. -f 4-\&" \&.
    Show some EXIF information, extracted by exifprobe/exifgrep
    
    .Sh DEPENDENCIES
    .Nm
    requires the
    .Cm jpegtran
    binary
    .Pq usually distributed in Qo libjpeg-progs Qc or similar
    for lossless rotation.
    .Pp
    To view images from URLs such as http://, you need to have
    .Cm wget
    available or use the builtin HTTP client
    .Pq see Cm --builtin .

    Xinerama support does not really work on Xinerama screens != 0.
    
    Thumbnail mode is somewhat inefficient, and because of that not nearly as fast
    as it could be.
