VERSION

This manual documents 2.19

Compile-time switches: libcurl support enabled, Xinerama support enabled, builtin EXIF support enabled

DESCRIPTION

is a mode-based image viewer. It is especially aimed at command line users who need a fast image viewer without huge GUI dependencies, though it can also be started by (graphical) file managers to view an image. By default (unless arguments or a filelist are specified) displays all files in the current directory.

supports filelists, various image sorting modes, image captions, HTTP and more. Configurable keyboard and mouse shortcuts are used to control it.

In many desktop environments, can also be used as wallpaper setter.

EXIF tags are supported either using exiv2 / exifgrep via --info (see the Sx USAGE EXAMPLES section ) or as a builtin feature by compiling with exif=1. In this build of , builtin EXIF support is enabled.

MODES

is based on various modes, which are selected at startup by command line options.

Slideshow mode is the default. It opens a window and displays the first image in it; the slideshow position can be advanced (or otherwise changed) using keyboard and mouse shortcuts. In slideshow mode, images can be deleted either from the filelist or from the disk, a changed filelist can also be saved to the disk and reopened at a later time. An image can also be read from stdin via Qq feh - .

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.

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.

Thumbnail mode is like index mode, but the mini-images are clickable and open the selected image in a new window.

Multiwindow mode shows images in multiple windows, instead of as a slideshow in one window. Don't use with a large filelist ;)

List mode doesn't display images. Instead, it outputs an ls - style listing of the files in the filelist, including image info such as size, number of pixels, type, etc. There is also a Customlist mode which prints image info in a custom format specified by a printf-like format string.

can also list either all the loadable files in a filelist or all the unloadable files. This is useful for preening a directory.

SUPPORTED FORMATS

can open any format supported by Imlib2, most notably jpeg, png, pnm, tiff, and bmp. The gif format is also supported, but only for static images. In case of animations, only the first frame will be shown. If the convert binary (supplied by ImageMagick) is available, it also has limited support for many other filetypes, such as svg, xcf and otf. Use --magick-timeout num with a non-negative value to enable it.

OPTIONS

-A , --action [flag [[ title ] action ] ]

Specify a shell command as an action to perform on the image. In slideshow or multiwindow mode, the action will be run when the action_0 key is pressed, in list mode, it will be run for each file. In loadable/unloadable mode, it will be run for each loadable/unloadable file, respectively. In thumbnail mode, clicking on an image will cause the action to run instead of opening the image.

If flag is Qq ; , will reload the current image instead of switching to the next one (slideshow mode) or closing the window (multiwindow mode) after executing the action. If [ title is specified (note the literal Qo [ Qc and Qo ] Qc , ) --draw-actions will display title instead of action in the action list. Note that title must not start with a space. If it does, the action is handled as if it did not have a title. This special case exists for backwards compatibility reasons and makes sure that actions like Qq [ -L %F ] && foo still work.

The action will be executed by /bin/sh. Use format specifiers to refer to image info, see Sx FORMAT SPECIFIERS for details. Example usage: Qq feh -A Qo mv ~/images/%N Qc * .

--action1 .. --action9 [flag [[ title ] action ] ]

Extra actions which can be set and triggered using the appropriate number key.

--auto-rotate

(only if compiled with exif=1) Automatically rotate images based on EXIF data. Does not alter the image files.

-Z , --auto-zoom

Zoom pictures to screen size in fullscreen / fixed geometry mode.

-x , --borderless

Create borderless windows.

-P , --cache-thumbnails

Enable thumbnail caching in ~/.thumbnails Only works with thumbnails <= 256x256 pixels.

-K , --caption-path path

Path to directory containing image captions. This turns on caption viewing, and if captions are found in 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 .

-L , --customlist format

Don't display images, print image info according to format instead. See Sx FORMAT SPECIFIERS .

--cycle-once

Exit after one loop through the slideshow.

-G , --draw-actions

Draw the defined actions and what they do at the top-left of the image.

--draw-exif

(only if compiled with exif=1) display some EXIF information in the bottom left corner, similar to using --info with exiv2 / exifgrep .

-d , --draw-filename

Draw the filename at the top-left of the image.

--draw-tinted

Show overlay texts (as created by --draw-filename et al ) on a semi-transparent background to improve their readability

-f , --filelist file

This option is similar to the playlists used by music software. If 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 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 (-Spixels for example ) for later viewing.

Any changes to the internal filelist (such as deleting a file or it being pruned for being unloadable) will be saved to file when exits. You can add files to filelists by specifying them on the command line when also specifying the list.

If file is Qq - , will read the filelist from its standard input.

-e , --font 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 .

-C , --fontpath path

Specify path as extra directory in which to search for fonts; can be used multiple times to add multiple paths.

--force-aliasing

Disable antialiasing for zooming, background setting etc.

-I , --fullindex

Same as index mode, but with additional information below the thumbnails. Works just like Qq feh --index --index-info %n\n%S\n%wx%h . Enables Sx MONTAGE MODE OPTIONS .

Note: This option needs to load all images to calculate the dimensions of the window, so when using it with many files it will take a while before a window is visible. Use --preload to get a progress bar.

-F , --fullscreen

Make the window fullscreen. Note that in this mode, large images will always be scaled down to fit the screen, --zoom zoom only affects smaller images and never scales larger than necessary to fit the screen size. The only exception is a zoom of 100, in which case images will always be shown at 100% zoom, no matter their dimensions.

When combined with --thumbnails this option only affects images opened from the thumbnail overview. The thumbnail list itself will still be windowed.

-g , --geometry [width x height [+ x + y ] ]

Limit (and don't change) the window size. Takes an X-style geometry string like 640x480 with optional +x+y window offset. Note that larger images will be zoomed out to fit, but you can see them at 1:1 by clicking the zoom button. Also note that this option does not enforce the geometry, changing it by a tiling WM or manually is still possible. After each resize, the resulting window size is used as the new size limit.

-Y , --hide-pointer

Hide the pointer (useful for slideshows)

-B , --image-bg style

Use style as background for transparent image parts and the like. Accepted values: checks, white, black. The default for windowed mode is checks, while fullscreen defaults to black.

-i , --index

Enable Index mode. Index mode is similar to montage mode, and accepts the same options. It creates an index print of thumbnails, printing the image name beneath each thumbnail. Index mode enables certain other options, see Sx INDEX AND THUMBNAIL MODE OPTIONS and Sx MONTAGE MODE OPTIONS .

--info [flag commandline ]

Execute commandline and display its output in the bottom left corner of the image. Can be used to display e.g. image dimensions or EXIF information. Supports Sx FORMAT SPECIFIERS . If flag is set to Qo ; Qc , the output will not be displayed by default, but has to be enabled by the toggle_info key.

-k , --keep-http

When viewing files using HTTP, normally deletes the local copies after viewing, or, if caching, on exit. This option permanently stores them on disk, either in the directory specified by --output-dir or in the current working directory.

--insecure

When viewing files with HTTPS, this option disables strict hostname and peer checking. This allows images on sites with self-signed certificates to be opened, but is no more secure than plain HTTP.

--keep-zoom-vp

When switching images, keep zoom and viewport settings (zoom level and X, Y offsets)

-l , --list

Don't display images. Analyze them and display an ls(1)-Nostyle listing. Useful in scripts to hunt out images of a certain size/resolution/type etc.

-U , --loadable

Don't display images. Just print out their names if imlib2 can successfully load them. Returns false if at least one image failed to load.

--magick-timeout timeout

Stop trying to convert unloadable files after timeout seconds. A negative value disables covert / magick support altogether, a value of zero causes to try indefinitely. By default, magick support is disabled.

--max-dimension width x height

Only show images with width <= width and height <= height If you only care about one parameter, set the other to 0 (or a negative value)

-M , --menu-font font

Use font (truetype, with size, like Qq yudit/12 ) as menu font.

--min-dimension width x height

Only show images with width >= width and height >= height If you only care about one parameter, set the other to 0.

-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 .

-w , --multiwindow

Disable slideshow mode. With this setting, instead of opening multiple files in slideshow mode, multiple windows will be opened; one per file.

--no-jump-on-resort

Don't jump to the first image after resorting the filelist.

-N , --no-menus

Don't load or show any menus.

--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.

--no-xinerama

Disable Xinerama support. Only makes sense when you have Xinerama support compiled in.

-j , --output-dir directory

Save files to directory (only useful with -k) By default, files are saved in the current working directory.

-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.

-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.

-z , --randomize

When viewing multiple files in a slideshow, randomize the file list before displaying. The list is re-randomized whenever the slideshow cycles (that is, transitions from last to first image).

-r , --recursive

Recursively expand any directories in the commandline arguments to the content of those directories, all the way down to the bottom level.

--no-recursive

Don't recursively expand any directories (enabled by default). Useful to override theme options.

-R , --reload int

Reload filelist and current image after int seconds. Useful for viewing HTTP webcams or frequently changing directories. (Note that the filelist reloading is still experimental.)

If an image is removed, will either show the next one or quit. However, if an image still exists, but can no longer be loaded, will continue to try loading it.

-n , --reverse

Reverse the sort order. Use this to invert the order of the filelist. E.g. to sort in reverse width order, use -nSwidth

-. , --scale-down

Scale images to fit window geometry (defaults to screen size when no geometry was specified). Note that the window geometry is not updated when changing images at the moment. This option is recommended for tiling window managers. This option is ignored when in fullscreen and thumbnail list mode.

In tiling environments, this also causes the image to be centered in the window.

--scroll-step count

Scroll count pixels whenever scroll_up, scroll_down, scroll_left or scroll_right is pressed. Note that this option accepts negative numbers in case you need to inverse the scroll direction; see Sx KEYS CONFIG SYNTAX to change it permanently. Default: 20

-D , --slideshow-delay float

For slideshow mode, wait float seconds between automatically changing slides. Useful for presentations. Specify a negative number to set the delay (which will then be float * (-1) ) but start in paused mode.

-S , --sort sort_type

The file list may be sorted according to image parameters. Allowed sort types are: name, filename, dirname, mtime, width, height, pixels, size, format. For sort modes other than name, filename, dirname, or mtime, a preload run will be necessary, causing a delay proportional to the number of images in the list.

The mtime sort mode sorts images by most recently modified. To sort by oldest first, reverse the filelist with --reverse.

-| , --start-at filename

Start the filelist at filename Note that at the moment, filename must match an (expanded) path in the filelist. So, if the file to be matched is passed via an absolute path in the filelist, filename must be an absolute path. If the file is passed via a relative path, filename must be an identical relative path. This is a known issue. See also Sx USAGE EXAMPLES .

-T , --theme theme

Load options from config file with name theme - see Sx THEMES CONFIG SYNTAX for more info. Note that commandline options always override theme options. The theme can also be set via the program name (e.g. with symlinks) so by default will look for a Qq Nm theme.

-t , --thumbnails

Same as Index mode, but the thumbnails are clickable image launchers. Note that --fullscreen and --scale-down do not affect the thumbnail window. They do, however, work for image windows launched from thumbnail mode. Also supports Sx INDEX AND THUMBNAIL MODE OPTIONS as well as Sx MONTAGE MODE OPTIONS .

-~ , --thumb-title string

Set title for windows opened from thumbnail mode. See also Sx FORMAT SPECIFIERS .

-^ , --title title

Set window title. Applies to all windows except those opened from thumbnail mode. See Sx FORMAT SPECIFIERS .

-u , --unloadable

Don't display images. Just print out their names if imlib2 can NOT successfully load them. Returns false if at least one image was loadable.

-V , --verbose

output useful information, progress bars, etc.

-v , --version

output version information and exit.

--xinerama-index screen

Override 's idea of the active Xinerama screen. May be useful in certain circumstances where the window manager places the feh window on Xinerama screen A while assumes that it will be placed on screen B.

In background setting mode: When used with any option other than --bg-tile Only set wallpaper on screen All other screens will be filled black/white. This is most useful in a Xinerama configuration with overlapping screens. For instance, assume you have two overlapping displays (index 0 and 1), where index 0 is smaller. To center a background on the display with index 0 and fill the extra space on index 1 black/white, use Qq --xinerama-index 0 when setting the wallpaper.

--zoom percent | max | fill

Zoom images by percent when in full screen mode or when window geometry is fixed. When combined with --auto-zoom zooming will be limited to the specified percent Specifying max is like setting --auto-zoom using fill makes zoom the image like the --bg-fill mode.

MONTAGE MODE OPTIONS

These additional options can be used for index, montage and (partially) thumbnail mode.

-a , --alpha int

When drawing thumbnails onto the background, set their transparency level to int (0 - 255)

-b , --bg file | trans

Use file as background for your montage. With this option specified, the montage size will default to the size of file if no size restrictions were specified. Alternatively, if file is Qq trans , the background will be made transparent.

-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 --thumb-width and --thumb-height This will prevent any empty space in the final montage.

-H , --limit-height pixels

Limit the height of the montage.

-W , --limit-width pixels

Limit the width of the montage, defaults to 800 pixels.

If both --limit-width and --limit-height are specified, the montage will be exactly width x height pixels in dimensions.

-o , --output file

Save the created montage to file

-O , --output-only file

Just save the created montage to file without displaying it.

-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 thumbnail size. Aspect ratio will be maintained unless --ignore-aspect is specified.

-E , --thumb-height pixels

Set thumbnail height.

-y , --thumb-width pixels

Set thumbnail width.

-J , --thumb-redraw n

Only relevant for --thumbnails Redraw thumbnail window every n images. In <= 1.5, the thumbnail image used to be redrawn after every computed thumbnail (so, it updated immediately) However, since the redrawing takes quite long (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 n = 1 to get the old behaviour, n = 0 will only redraw once all thumbnails are loaded.

INDEX AND THUMBNAIL MODE OPTIONS

--index-info format

Show image information based on format below thumbnails in index / thumbnail mode. See Sx FORMAT SPECIFIERS . May contain newlines. Use Qq --index-info '' to display thumbnails without any info text

Note: If you specify image-related formats (such as %w or %s) needs to load all images to calculate the dimensions of its own window. So when using them with many files, it will take a while before a window becomes visible. Use --preload to get a progress bar.

-@ , --title-font font

Set font to print a title on the index, if no font is specified, no title will be printed.

BACKGROUND SETTING

In many desktop environments, can also be used as a background setter. Unless you pass the --no-fehbg option, it will write a script to set the current background to ~/.fehbg So to have your background restored every time you start X, you can add Qq sh ~/.fehbg & to your X startup script (such as ~/.xinitrc ) As of 2.13, this script is executable, so Qq ~/.fehbg & will work as well.

Note that does not support setting the wallpaper of GNOME shell desktops. In this environment, you can use Qq gsettings set org.gnome.desktop.background picture-uri file:/// Ns Ar path instead.

For the --bg-center and --bg-max options, you can use the --geometry option to specify an offset from one side of the screen instead of centering the image. Positive values will offset from the left/top side, negative values from the bottom/right. +0 and -0 are both valid and distinct values.

Note that all options except --bg-tile support Xinerama. For instance, if you have multiple screens connected and use e.g. --bg-center will center or appropriately offset the image on each screen. You may even specify more than one file, in that case, the first file is set on screen 0, the second on screen 1, and so on.

Use --no-xinerama to treat the whole X display as one screen when setting wallpapers. You may also use --xinerama-index to use as a background setter for a specific screen.

--bg-center

Center the file on the background. If it is too small, it will be surrounded by a black border

--bg-fill

Like --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

--bg-max

Like --bg-fill but scale the image to the maximum size that fits the screen with black borders on one side.

--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

--bg-tile

Tile (repeat) the image in case it is too small for the screen

--no-fehbg

Do not write a ~/.fehbg file

CONFIGURATION

has three config files: themes for theme definitions, keys for key bindings and buttons for mouse button bindings. It will try to read them from $XDG_CONFIG_HOME/feh/ which (when XDG_CONFIG_HOME is unset) defaults to ~/.config/feh/ If the files are not found in that directory, it will also try /etc/feh/

All config files treat lines starting with a Qq # character as comments. Note that mid-line comments are not supported.

THEMES CONFIG SYNTAX

.config/feh/themes allows the naming of option groups, called themes.

It takes entries of the form Qq Ar theme options ... , where theme is the name of the entry and options are the options which will be applied when the theme is used. Note that the options are not parsed by any shell. Therefore, filename expansion Po Qq *.jpg and similar Pc is not supported. Quoting with both single and double quotes works, though.

An example entry would be Qq imagemap -rVq --thumb-width 40 --thumb-height 30 --index-info '%n\n%wx%h' .

You can use this theme in two ways. Either call Qo -Timagemap *.jpg Qc , or create a symbolic link to with the name of the theme you want it to use. For the example above, this would be Qo ln -s `which ` ~/bin/imagemap Qc . Now just run Qq imagemap *.jpg to use these options.

Note that you can split a theme over several lines by placing a backslash at the end of an unfinished line.

Command line options always override theme options.

KEYS CONFIG SYNTAX

.config/feh/keys defines key bindings. It has entries of the form Qq Ar action Op Ar key1 Op Ar key2 Op Ar key3 .

Each key is an X11 keysym name as shown by xev(1), like Qq Delete . It may optionally start with modifiers for things like Control, in which case key looks like mod - keysym Po for example Qq C-Delete for Ctrl+Delete or Qq C-1-Delete for Ctrl+Alt+Delete Pc

Available modifiers are C for Control S for Shift and 1 , 4 for Mod1 and Mod4 To match an uppercase letter like Qq S instead of Qq s , the Shift modifier is not required.

Specifying an action without any keys unbinds it (i.e. the default bindings are removed).

Note Do not use the same keybinding for multiple actions. When binding an action to a new key (or mouse button) make sure to unbind it from its previous action, if present. does not check for conflicting bindings, so their behaviour is undefined.

For a list of the action names, see Sx KEYS .

KEYS

In an image window, the following keys may be used (The strings in Bo square brackets Bc are the config action names )

a Bq toggle_actions

Toggle actions display (see --draw-actions )

A Bq toggle_aliasing

Enable/Disable anti-aliasing

c Bq toggle_caption

Caption entry mode. If --caption-path has been specified, then this enables caption editing. The caption at the bottom of the screen will turn yellow and can be edited. Hit return to confirm and save the caption, or escape to cancel editing. Note that you can insert an actual newline into the caption using Aq CTRL+return .

BUTTONS CONFIG SYNTAX

.config/feh/buttons This works like the keys config file: the entries are of the form Qq Ar action Op Ar binding .

Each binding is a button number. It may optionally start with modifiers for things like Control, in which case binding looks like mod - button (for example C-1 for Ctrl + Left button)

Note Do not use the same button for multiple actions. does not check for conflicting bindings, so their behaviour is undefined. Either unbind the unwanted action, or bind it to another unused button. The order in which you bind / unbind does not matter, though.

For the available modifiers, see Sx KEYS CONFIGURATION SYNTAX .

BUTTONS

In an image window, the following buttons may be used (The strings in Bo square brackets Bc are the config action names ) Additionally, all actions specified in the Sx KEYS section can also be bound to a button.

unbound Bq reload

Reload current image

1 Ao left mouse button Ac Bq pan

pan the current image

2 Ao middle mouse button Ac Bq zoom

Zoom the current image

3 Ao right mouse button Ac Bq toggle_menu

Toggle menu

4 Ao mousewheel down Ac Bq prev_img

Show previous image

5 Ao mousewheel up Ac Bq next_img

Show next image

Ctrl+1 Bq blur

Blur current image

Ctrl+2 Bq rotate

MOUSE ACTIONS

Default Bindings: When viewing an image, mouse button 1 pans the image (moves it around) or, when only clicked, moves to the next image (slideshow mode only) Quick drags with less than 2px of movement per axis will be treated as clicks to aid graphics tablet users. Mouse 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.

CTRL+Button 1 blurs or sharpens the image (drag left to blur, right to sharpen) CTRL+Button 2 rotates the image around the center point.

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, will warp your cursor to the opposite border so you can continue panning.

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.

SIGNALS

In slideshow mode, handles the following signals:

SIGUSR1

Switch to next image

SIGUSR2

Switch to previous image

USAGE EXAMPLES

Here are some examples of useful option combinations. See also: Aq feh.finalrewind.org/examples

feh /opt/images

Show all images in /opt/images

feh -r /opt/images

Recursively show all images found in /opt/images and subdirectories

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.

feh -t -Sfilename -E 128 -y 128 -W 1024 /opt/images

Show 128x128 pixel thumbnails, limit window width to 1024 pixels.

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.

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

feh --unloadable -r /opt/images

Print all unloadable images in /opt/images, recursively

feh -f by_width -S width --reverse --list .

Write a list of all images in the directory to by_width, sorted by width (widest images first)

feh -w /opt/images/holidays

Open each image in /opt/images/holidays in its own window

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

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

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

feh --start-at foo.jpg

Same as above

feh --info "exifgrep '(Model|DateTimeOriginal|FNumber|ISO|Flash)' %F | cut -d . -f 4-" .

Show some EXIF information, extracted by exifprobe/exifgrep

feh --action 'rm %F' -rl --max-dim 1000x800

Recursively remove all images with dimensions below or equal to 1000x800 pixels from the current directory.

DEPENDENCIES

requires the jpegtran and jpegexiforient binaries (usually distributed in Qo libjpeg-progs Qc or similar ) for lossless rotation.

To view images from URLs such as http://, you need compiled with libcurl support (enabled by default). See the Sx VERSION section.

BUGS

On systems with giflib 5.1.2, may be unable to load gif images. For affected mips, mipsel and arm devices, gif support is completely broken, while on x86 / x86_64 gifs can usually only be loaded if they are the first image in the filelist. This appears to be a bug in giflib, see Aq bugs.debian.org/cgi-bin/bugreport.cgi?bug=813729 for details. Workaround: Use --magick-timeout 5 (or some other positive value) to load gifs with imagemagick instead, or downgrade to giflib 5.1.1, or upgrade to giflib 5.1.4.

Thumbnail mode is somewhat inefficient, and because of that not nearly as fast as it could be.

--scale-down does not take window decorations into account and may therefore make the window slightly too large.

REPORTING BUGS

If you find a bug, please report it to Aq derf+feh@finalrewind.org or via Aq github.com/derf/feh/issues . You are also welcome to direct any feh-related comments/questions/... to #feh on irc.oftc.net.

Please include the feh version Aq the output of Qq feh --version , steps to reproduce the bug and, if necessary, images to reproduce it.

FUTURE PLANS

Plans for the following releases:

• Make zoom options more intuitive
