Welcome to the FIM (Fbi IMproved) image viewer program homepage

FIM is a lightweight universal image viewer, mostly for Linux (but not only).  
FIM aims to be a highly customizable and scriptable image viewer for users who are comfortable with software like the VIM text editor (see this minitutorial) or the Mutt mail user agent (see this minitutorial).  
It has been developed with Linux in mind, but can be built to run on several Unix systems or even on MS-Windows.
 
It is lightweight: it depends on a relatively few libraries, it displays in full screen and you control it using the keyboard.
It is universal: it can open many file formats and it can display pictures in the following video modes:

• Graphically, with the Linux framebuffer device (see screenshots).
• Graphically, under X/Xorg, using the SDL library (see screenshots).
• Graphically, under X/Xorg, using the Imlib2 library (see screenshots).
• Rendered as ASCII Art in any textual console, using the AAlib library (see screenshots).

The right video mode gets auto-detected or selected at runtime, and may be opted in/out before build at configure time, if desired.
 
FIM is free software (see licensing info) and it is richly documented (see the documentation section).
 
Its official web page is hosted on Savannah: http://savannah.nongnu.org/projects/fbi-improved/
 
The official mirror for stable releases is located on Savannah mirror network: http://download.savannah.nongnu.org/releases/fbi-improved
 
The official mailing list is at: http://savannah.nongnu.org/mail/?group=fbi-improved
 
FIM is an idea by Michele Martone, although inspiration has been drawn from other softwares as well as from certain science fiction movie scenes.  
FIM started as a fork of the Fbi image viewer by Gerd Hoffmann.

Tutorial: VI/VIM-like feel in FIM

• The motion keys: j (like 'down' arrow), k (like 'up' arrow), h (like 'left' arrow), l (like 'right' arrow),
• Repeat any interactive command by prepending it by a number.
  E.g.: magnify two times in a row by pressing 2+
• Filename based search.
  E.g.: jump to a file containing 'dog' in its name by pressing: / and entering dog then Enter.
  
• Search backwards using ? instead of /.
• Repeat the last action by pressing ..
• Jump to the first file by pressing ^ or to the last file by pressing $.
• Enter in command line mode by pressing : and Enter to go back in interactive mode.
• When in command line mode
  • type any command, like e.g. help and execute it after pressing Enter.
  • type a number and then Enter to jump to the image with that index in the list.
  • use the up and down arrows to navigate the history (via the GNU history library).
  • if using the framebuffer, GNU Emacs-like (via GNU readline, just as in BASH) command line editing is possible.
• Execute a command after startup: fim -c command.
• Read an image via standard input, e.g.: cat image.jpg | fim -i (note the difference: in VIM it's-, not -i).
  This is meant to be used with converters, e.g.: convert image.pic ppm:- | fim -i.
• Set autocommands with the autocmd command.

News: What's new with FIM

(last update: 19/07/2017)

	
	FIM NEWS -- history of (main) user-visible changes in FIM.

                Version 0.5-rc3

 * fix: mouse movement under SDL used to trigger unnecessary screen redraws.
 * bugfix: on certain framebuffer configurations part of the screen would not be redrawn.
 * bugfix: conversion from external program was vulnerable to failure due to missing check.
 * fix: gif error handling could have led to NULL pointer usage.
 * fix: the largest mipmap was not always being used.
 * fix: -lfl linkage is not really necessary: removed it.
 * fix: support for PPM files with 2 bytes per sample.
 * fix: configure script regex_t check was unnecessarily broken
 * fix: was likely using uninitialized data in Image()
 * fix: a few more checks when reading PCX files
 * documented the %k expando for _info_fmt_str and bugfix (avoiding data corruption when handling %k)
 * to ease reproducible builds: imposing LC_ALL=C to $(YACC) and $(SORT), vim2html.pl reads SOURCE_DATE_EPOCH
 * fix: when stdint.h is available use uint8_t, uint16_t, uint32_t instead of non-portable __u8, __u16, __u32
 * fix: ./configure --disable-pcx was not properly disabling PCX format support
 * fix: compilation was broken without framebuffer (FIM_WITH_NO_FRAMEBUFFER)
 * fix: compilation was broken without FIM_WITH_LIBSDL configured in
 * fix: with _re_search_opts='f' the in-descriptions search was broken
 * fix: removed obsolete documentation for the "window" command, now disabled
 * bugfix: repeating "recording 'repeat_last'" (default '.' key) by prepending a number now works
 * fix: cleaned up the internal keysyms initialization code
 * fix: lastly used image will be erased at last, after eventually prefetched images.
 * fix: configure will try to detect curses/ncurses.
 * fix: configure will use `sdl-config --static-lib`'.
 * fix: a check was missing in the PS decoder when reading from stdin.
 * bugfix: --offset option was ignoring lower bytes-offset.
 * fix in _seek_magic and documentation.
 * fix: in --offset mode, avoiding probing for external loader programs, handling of larger offsets.
 * fix: 'recording' command non functioning properly.
 * fix: configure would fail on --disable-aa and absent aalib.

                Version 0.5-rc2

 * configure will autodetect and turn aalib on by default
 * fix: will emit more precise diagnostics on unsupported device string
 * fix: adjusted man pages for roff cleanliness
 * fix: typos fixed in the documentation

                Version 0.5-rc1

   controlled by the use of special image variable specifiers ('expandos'):
    "%T" expando to get (and display) total memory used by the program 
    "%C" expando to get (and display) file/memory usage by image cache
    "%M" expando to get (and display) memory used by the current (displayed) image
    "%c" expando to get (and display) centering information
    "%m" expando to get (and display) current image mipmap occupation information
    "%k" expando to get (and display) current image i:_comment value
    "%?PRE?VAR?POST?" expando to get (and display) "PRE".i:VAR."POST"
    ...
 * search (and jump) on image descriptions via 'goto' and key '/'
 * when repeating search with 'repeat_last', will use last direction
 * '?' key is now assigned to backward search (goto '-//')
 * default 'C-p' key is now assigned to repeat last backward search (goto '-//')

   "#!fim:var="      (to unset i:var=value on all all the files following)
   "filename #!fim:=" (to i:_comment from the value read last)
   "filename #!fim:+comment" (similar, but will append the new comment)
   "filename #!fim:^comment" (similar, but will prepend the new comment)
   "filename #!fim:s/f/t" (similar, but replace string f with string t)

fim

NAME

fim - fbi (linux framebuffer imageviewer) improved

SYNOPSIS

fim [{options}] [--] {imagefile} [{imagefiles}]
... | fim [{options}] [--] [{imagefiles}] -
fim [{options}] [--] [{files}] - < {file_name_list_text_file}
fim --image-from-stdin [{options}] < {imagefile}
fim --script-from-stdin [{options}] < {scriptfile}

DESCRIPTION

fim is a ’swiss army knife’ for displaying image files. It is capable of displaying image files using different graphical devices while offering a uniform look and feel; it features an internal command language specialized to the image viewing purposes; it is capable of interacting with standard input and output; the internal command language is accessible via a command line capable of autocompletion and history; it features command recording, supports initialization files, customizable key bindings, internal variables and command aliases, vim-like autocommands, JPEG comments, EXIF tags display, EXIF rotation/orientation, and much more.

As a default, fim displays the specified file(s) on the detected graphical device (e.g. with SDL if X is detected, or the linux framebuffer device if not). JPEG,PNG,GIF,BMP,TIFF,PPM,PGM,PBM,PCX formats are supported. For ’XCF’ (Gimp’s) images, fim will try to use ’xcftopnm’. For ’.FIG’ vectorial images, fim will try to use ’fig2dev’. For ’.DIA’ vectorial images, fim will try to use ’dia’. For ’.SVG’ vectorial images, fim will try to use ’inkscape’. For other formats fim will try to use ImageMagick’s ’convert’ executable.

If {imagefile} is a directory, therein contained files of supported formats will be loaded. If {imagefile} contains a trailing slash (/), it will be treated as a directory; otherwise a check will be made using stat(2). To change this default, see description of the _pushdir_re variable and the --no-stat-push and --recursive options.

If configured at build time, fim will be capable of using SDL or aalib output.

This man page only describes the fim command line options. See man fimrc(5) for a full specification of the fim language, commands, variables, and an example configuration file.

USAGE

You may invoke fim from an interactive shell and control it with the keyboard, as you would do with any image viewer with reasonable key bindings.

fim is keyboard oriented: there are no user menus or buttons available. If you need some feature or setting which is not accessible from the default keyboard configuration, you probably need a custom configuration or simply need to type a custom command. For these, you can use the internal command and configuration language. The full specification for these is accessible at runtime using the internal help system (typing :help).

OPTIONS

Accepted command line {options} :

-a, --autozoom

Enable autozoom. fim will automagically pick a reasonable zoom factor when loading a new image (as in fbi).

-b, --binary[=24|1]

Display (any filetype) binary files contents as they were raw 24 or 1 bits per pixel pixelmaps. Will arrange the image by rows long as specified by the _preferred_rendering_width variable for the image width (unless a narrower image suffices). Regard this as an easter bunny option.

--as-text

Display (any filetype) files contents as they were text. Will only show printable characters. Regard this as an easter bunny option.

--cd-and-readdir

Step into the first loaded file directory and push other files.

-c {commands}, --execute-commands {commands}

The commands string will be executed before entering the interactive loop. Please note that if your commands are more complicated than a simple ’next’ or ’pornview’ command, they must be quoted and escaped in a manner suitable for your shell!

For example, -c ’*2;2pan_up;display;while(1){bottom_align;sleep "1" ; top_align}’ (with the single quotes) will tell fim to first double the displayed image size, then pan two times up, then display the image ; and then do an endless loop consisting of bottom and top aligning, alternated.

-C {commands}, --execute-commands-early {commands}

Just as the --execute-commands option, but commands will be executed before the loading of any config file.

For example, -C ’_scale_style=" "’ will make fim start with no auto-scaling.

-d {framebuffer device}, --device {framebuffer device}

Framebuffer device to use. Default is the one your vc is mapped to (as in fbi).

--dump-reference-help[=man].

Will dump to stdout the language reference help.

-D, --dump-default-fimrc

The default configuration (the one hardcoded in the fim executable) is dumped on standard output and fim exits.

-E {scriptfile}, --execute-script {scriptfile}

The scriptfile will be executed right after the default initialization file is executed.

-f {fimrc}, --etc-fimrc {fimrc}

Specify an alternative system wide initialization file (default: /usr/local/etc/fimrc), which will be executed prior to any other configuration file.

-F {commands}, --final-commands {commands}

The commands string will be executed after exiting the interactive loop of the program (right before terminating the program).

-h, --help[=s|d|l|m]

Print (short, descriptive, long, or complete man) program invocation help, and terminate.

--load-image-descriptions-file {filename}

Load image descriptions from {filename}. In {filename} each line is the name of an image file (its basename will be taken), then a Tab character (unless --image-descriptions-file-separator specifies otherwise), then the description text. Each description will be put in the _comment variable of the image at load time. Will override the comment eventually loaded from the file (e.g. JPEG, PNG or TIFF comment). Special comment lines like "#!fim:var=val" will lead i:var to be assigned value val (unquoted) at image loading time. Special description lines begin with markers: with "#!fim:=" the last description line to be used; with "#!fim:+" what follows + will be appended to the last description line; with "#!fim:^" what follows ^ will be prepended to the last description line; with "#!fim:s/f/t" the last description line will be used, but occurrences of string f will be substituted with string t (f and t can contain anything but not a /). If val is empty that variable will be unset. These variables are stored also in an internal index used by the limit command. This option sets _caption_over_image=2, so that a caption will be displayed over the image.

--image-descriptions-file-separator {sepchar}

A character to be used as a separator between the filename and the description part of lines specified just before a --load-image-descriptions-file.

-i, --image-from-stdin

Will read one single image from the standard input (the image data, not the filename). May not work with all supported file formats. In the image list, this image will be displayed as "<STDIN>".

-m {vmode}, --mode {vmode}

Name of the video mode to use video mode (must be listed in /etc/fb.modes). Default is not to change the video mode. In the past, the XF86 config file (/etc/X11/XF86Config) used to contain Modeline information, which could be fed to the modeline2fb perl script (distributed with fbset). On many modern xorg based systems, there is no direct way to obtain a fb.modes file from the xorg.conf file. So instead one could obtain useful fb.modes info by using the (fbmodes (no man page AFAIK)) tool, written by bisqwit. An unsupported mode should make fim exit with failure. But it is possible the kernel could trick fim and set a supported mode automatically, thus ignoring the user set mode.

-N, --no-rc-file

No personal initialization file will be read (default is ~/.fimrc) at startup.

--no-etc-rc-file

No system wide initialization file will be read (default is /usr/local/etc/fimrc) at startup.

--no-internal-config

No internal default configuration at startup (uses internal variable _no_default_configuration). Will only provide a minimal working configuration.

--no-commandline

With internal command line mode disabled.

--no-history-save

Do not save execution history at finalization (uses internal variable _save_fim_history).

--no-history-load

Do not load execution history at startup.

--no-history

Do not load or save execution history at startup.

-p, --script-from-stdin

Will read commands from stdin prior to entering in interactive mode.

-o [fb|sdl|aa|dumb|imlib2], --output-device [fb|sdl|aa|dumb|imlib2]

Will use the specified device as fim video output device, overriding automatic checks.The available devices depend on the original configuration/compilation options, so you should get the list of available output devices issuing fim --version. The aa option may be specified as aa={[’w’]} ; the ’w’ character allows windowed mode in case of aalib running under X (otherwise, the DISPLAY environment variable will be unset for the current instance of fim). The sdl option may be specified as sdl={[’w’][’m’][’r’][’W’][’M’][’R’]width:height} , where width is and height are integer numbers specifying the desired resolution; the ’w’ character requests windowed mode; the ’m’ character requests mouse pointer display; the ’r’ character requests support for window resize; the same letters uppercase request explicit negation of the mentioned features.

--offset {bytes-offset[[:upper-offset]|+offset-range]}

Will use the specified offset (in bytes) for opening the specified files. If upper-offset is specified, further bytes will be probed, until upper-offset. If +offset-range is specified, so many further bytes will be probed. This is useful for viewing images on damaged file systems; however, since the internal variables representation is sizeof(int) bytes based, you have a limited offset range.

-P, --text-reading

Enable textreading mode. This has the effect that fim will display images scaled to the width of the screen, and aligned to the top. Useful if the images you are watching text pages, all you have to do to get the next piece of text is to press space (in the default key configuration, of course).

-s {value}, --scroll {value}

Set scroll steps for internal variable _steps (default is 20%).

--slideshow {number}

Interruptible slideshow mode; will wait for {number} of seconds (assigned to the _want_sleep_seconds variable after each loading; implemented by executing while(_fileindex<_filelistlen){sleep _want_sleep_seconds; next;} as a first command.

-S, --sanity-check

A quick sanity check before starting the interactive fim execution, but after the initialization.

-t, --no-framebuffer

Fim will not use the framebuffer but the aalib (ASCII art) driver instead (if you are curious, see (info aalib)). If aalib was not enabled at tompile time, fim will work without displaying images at all.

-T {terminal}, --vt {terminal}

The terminal will be used as virtual terminal device file (as in fbi). See (chvt (1)), (openvt (1)) for more info about this. Use (con2fb (1)) to map a terminal to a framebuffer device.

--sort-basename

Sort files list before browsing according to file basename’s.

-u, --random

Randomly shuffle the files list before browsing (seed depending on time() function).

--random-no-seed

Randomly shuffle the files list before browsing (no seeding).

-v, --verbose

Be verbose: show status bar.

-V, --version

Display program version, compile flags, enabled features, linked libraries information, supported filetypes/file loaders, and then terminate.

-w, --autowidth

Scale the image according to the screen width.

--no-auto-scale

Do not scale the images after loading (will set ’_scale_style=" "’;).

--autowindow

Will resize the window size (if supported) to the image size. Don’t use this with other image scaling options.

--no-stat-push

Sets _push_checks=0 before initialization, thus disabling file/dir existence checks with stat(2) at push push time (and speeding up startup).

-H, --autoheight

Scale the image according to the screen height.

-W {scriptfile}, --write-scriptout {scriptfile}

All the characters that you type are recorded in the file {scriptout}, until you exit Fim. This is useful if you want to create a script file to be used with "fim -c" or ":exec" (analogous to Vim’s -s and ":source!"). If the {scriptout} file exists, it will be not touched (as in Vim’s -w).

-, --read-from-stdin

Read file list from stdin: each line one file.

Note that these the three standard input reading functionalities (-i,-p and -) conflict : if two or more of them occur in fim invocation, fim will exit with an error and warn about the ambiguity.

See the section INVOCATION EXAMPLES below to read some useful (and unique) ways of employing fim.

--read-from-stdin-elds <arg>

Specify an endline delimiter string for breaking lines read via -/--read-from-stdin. Line text before the delimiter will be treated as names of files to load; the text after will be ignored until a newline. This is useful e.g. to description files as filename list files.

-A, --autotop

Align images to the top (UNFINISHED).

-q, --quiet

Quiet mode. Sets _display_status=0;_display_busy=0;.

-r {resolution}, --resolution {resolution}

Set resolution (UNFINISHED).

-R, --recursive

Push files/directories to the files list recursively.

PROGRAM RETURN STATUS

The program return status is 0 on correct operation; 252 on unsupported device specification; 248 on bad input; 255 on a generic error; 42 on a signal-triggered program exit; or a different value in case of an another error.
The return status may be controlled by the use of the quit command.

COMMON KEYS AND COMMANDS

The following keys and commands are hardcoded in the minimal configuration. These are working by default before any config loading, and before the hardcoded config loading (see variable _fim_default_config_file_contents).

n goto ’+1f’
p goto ’-1f’
+ magnify
- reduce
h pan ’left’
l pan ’right’
k pan ’up’
j pan ’down’
q quit
You can type a number before a command binding to iterate the assigned command:
3k 3pan ’up’

: enter command line mode
:{number} jump to {number}^th image in the list

:*{factor} scale the image by {factor}
:{scale}% scale the image to the desired {scale}
:+{scale}% scale the image up to the desired percentage {scale} (relatively to the original)
:-{scale}% scale the image down to the desired percentage {scale} (relatively to the original)

You can visualize all of the default bindings invoking fim --dump-default-fimrc | grep bind .
You can visualize all of the default aliases invoking fim --dump-default-fimrc | grep alias .

The Return vs. Space key thing can be used to create a file list while reviewing the images and use the list for batch processing later on.

All of the key bindings are reconfigurable; see the default fimrc file for examples on this, or read the complete manual: the FIM.TXT file distributed with fim.

AFFECTING ENVIRONMENT VARIABLES

If using a gzipped font, the zcat program will be used to uncompress it (via execvp(3)).
If not specified, the following files will be probed and the first existing will be selected:

/usr/share/consolefonts/Uni3-TerminusBoldVGA14.psf.gz
/usr/lib/kbd/consolefonts/lat9-16.psf.gz
/usr/share/consolefonts/lat1-16.psf
/usr/share/consolefonts/lat1-16.psf.gz
/usr/share/consolefonts/lat1-16.psfu.gz
/usr/share/kbd/consolefonts/lat1-16.psf
/usr/share/kbd/consolefonts/lat1-16.psf.gz
/usr/share/kbd/consolefonts/lat1-16.psfu.gz
/usr/lib/kbd/consolefonts/lat1-16.psf
/usr/lib/kbd/consolefonts/lat1-16.psf.gz
/usr/lib/kbd/consolefonts/lat1-16.psfu.gz
/lib/kbd/consolefonts/lat1-16.psf
/lib/kbd/consolefonts/lat1-16.psf.gz
/lib/kbd/consolefonts/lat1-16.psfu.gz
/lib/kbd/consolefonts/Lat2-VGA14.psf.gz

/lib/kbd/consolefonts/Lat2-VGA8.psf.gz
/lib/kbd/consolefonts/Uni2-VGA16.psf.gz
/usr/share/consolefonts/default8x16.psf.gz
/usr/share/consolefonts/default8x9.psf.gz
/usr/share/consolefonts/Lat15-Fixed16.psf.gz
/usr/share/consolefonts/default.psf.gz
fim://

If the special fim:// string is specified, a hardcoded font will be used.

If unset, fim will probe for /dev/fb0.

COMMON PROBLEMS

fim needs read-write access to the framebuffer devices (/dev/fbN or /dev/fb/N), i.e you (our your admin) have to make sure fim can open the devices in rw mode. The IMHO most elegant way is to use pam_console (see /etc/security/console.perms) to chown the devices to the user logged in on the console. Another way is to create some group, chown the special files to that group and put the users which are allowed to use the framebuffer device into the group. You can also make the special files world writable, but be aware of the security implications this has. On a private box it might be fine to handle it this way through.

If using udev, you can edit : /etc/udev/permissions.d/50-udev.permissions and set these lines like here :
# fb devices
fb:root:root:0600
fb[0-9]*:root:root:0600
fb/*:root:root:0600

fim also needs access to the linux console (i.e. /dev/ttyN) for sane console switch handling. That is obviously no problem for console logins, but any kind of a pseudo tty (xterm, ssh, screen, ...) will not work.

INVOCATION EXAMPLES

fim media/
# Will load files from the directory media.

fim -R media/ --sort
# Will open files found by recursive traversal of directory media, then sorting the list.

find /mnt/media/ -name *.jpg | fim -
# Will make fim read the file list from standard input.

find /mnt/media/ -name *.jpg | shuf | fim -
# will make fim read the file list from standard input, randomly shuffled.

cat script.fim | fim -p images/*
# Will make fim read the script file script.fim from standard input prior to displaying files in the directory images

scanimage ... | tee scan.ppm | fim -i
# Will make fim read the image scanned from a flatbed scanner as soon as it is read

fim * > selection.txt
# Will output the file names marked interactively with the ’list "mark"’ command in fim to a file.

fim * | fim -
# will output the file names marked with ’m’ in fim to a second instance of fim, in which these could be marked again.

fim -c ’pread "vgrabbj -d /dev/video0 -o png";reload’
# will display an image grabbed from a webcam.

fim -o aa -c ’pread "vgrabbj -d /dev/video0 -o png";reload;system "fbgrab" "asciime.png"’
# if running in framebuffer mode, will save a png screenshot with an ASCII rendering of an image grabbed from a webcam.

fim -c ’while(1){pread "vgrabbj -d /dev/video0 -o png";reload;sleep 1;};’
# will display a sequence of images grabbed from a webcam; circa 1 per second.

NOTES

This manual page is neither accurate nor complete. In particular, issues related to driver selection shall be described more accurately. Also the accurate sequence of autocommands execution, variables application is critical to understanding fim, and should be documented. The filename "<STDIN>" is reserved for images read from standard input (view this as a limitation), and thus handling files with such name may incur in limitations. The SDL driver is quite inefficient, for a variety of reasons. In particular, its interaction with the readline library can be problematic (e.g.: when running in sdl mode without a terminal). This shall be fixed.

fim has bugs. Please read the BUGS file shipped in the documentation directory to discover the known ones.

fimrc

NAME

fimrc - fim configuration file and language reference

SYNOPSIS

~/.fimrc
/usr/local/etc/fimrc
fim --script-from-stdin [ {options} ] < {scriptfile}
fim --execute-script {scriptfile} [ {options} ]
fim --execute-commands {commands} [ {options} ]
fim --final-commands {commands} [ {options} ]
fim --write-scriptout {scriptfile} [ {options} ]
fim --write-scriptout /dev/stdout [ {options} ]

DESCRIPTION

This page explains the fim language, which is used for the fimrc configuration files, {scriptfile}s, or {commands} passed via command line {options}. This language can be used to issue commands (or programs) from the internal program command line accessed interactively through the ":" key (or rather, the key code specified by the "_console_key" variable). One may exit from command line mode by pressing the Enter key on an empty line (a non empty command line would be submitted for execution), or the Esc key (only in SDL mode). The general form of a fim command/program is shown in the next section.

FIM LANGUAGE GRAMMAR

This section specifies the grammar of the fim language.

Language elements surrounded by a single quote ("’") are literals.

Warning: at the present state, this grammar has conflicts. A future release shall fix them.

A STRING can be either a single quoted string or a double quoted string. A FLOAT is a floating point number. A QUOTED_FLOAT is a floating point number, either single ("’") or double (""") quoted. An INTEGER shall be an unsigned integer number. An IDENTIFIER shall be one of the valid fim commands (see COMMANDS REFERENCE ) or a valid alias. A VARIABLE shall be an already declared or undeclared variable identifier (see VARIABLES REFERENCE ) or a valid alias, created using the alias command. The "=~" operator treats the right expression as a STRING, and uses is as a regular expression for matching purposes. The SLASH_AND_REGEXP is a slash ("/") followed by a STRING, interpreted as a regular expression. See regex(1) for regular expression syntax.

The way some one-line statements are evaluated:

: enter command line mode
:{number} jump to {number}^th image in the list

:*{factor} scale the image by {factor}
:{scale}% scale the image to the desired {scale}
:+{scale}% scale the image up to the desired percentage {scale} (relatively to the original)
:-{scale}% scale the image down to the desired percentage {scale} (relatively to the original)

COMMANDS REFERENCE

alias
alias [{identifier} [{commands} [{description}]]]

align
align bottom : align to the lower side the current image; align top : align to the upper side the current image;

autocmd
autocmd {event} {pattern} {commands} : manipulate auto commands

autocmd_del
autocmd_del : manipulate auto commands. usage: autocmd_del {event} {pattern} {commands}

basename
basename {filename} : returns the basename of {filename}

bind
bind [{keysym} [{commands}]] : bind a keyboard symbol/shortcut {keysym} to {commands}; if {keysym} is at least two characters long and begins with 0 (zero), the integer number after the 0 will be treated as a raw keycode to bind the specified {keysym} to. activate the _verbose_keys variable to discover (display device dependent) raw keys.; binding is dynamical, so you can rebind keys even during program’s execution

cd
cd {path}: change the current directory to {path}. cd - will change to the previous current directory (before the last ":cd {path}" command)

clear
clear : clear the virtual console

commands
commands : display the existing commands

desaturate
desaturate : desaturate the displayed image colors. To get back the original you will have to reload the image.

desc
desc ’load’ {filename} [{sepchar}] : load description file {filename}, using the optional {sepchar} character as separator. See documentation of --load-image-descriptions-file for the format of {filename}.

display
display [’reinit’ {string}]|’resize’ {w} {h}] : display the current file contents; if ’reinit’ switch is supplied, the ’{string}’ specifier will be used to reinitialize (e.g.: change resolution, window system options) the display device; see documentation for the --output-device command line switch for allowed values of {string}; if ’resize’ and no argument, will ask the window manager to size the window like the image; if ’resize’ and two arguments, these will be used as width and height of window, to set.

dump_key_codes
dump_key_codes : dump the active key codes (unescaped, for inspection)

echo

goto
goto {[’+’|’-’]{number}[’%’][’f’|’p’]} | {/{regexp}/} | {’+//’}: jump to an image; if {number} is given, and not surrounded by any specifier, will go to image at index {number} ; if followed by ’%’, the effective index will be computed as a percentage to the current available images; if prepended by ’-’ or ’+’, the jump will be relative to the current index; the ’f’ specifier asks for the jump to occur within the files; the ’p’ specifier asks for the jump to occur in terms of pages, within the current file; if /{regexp}/ is given, will jump to the first image matching the given /{regexp}/ regular expression pattern; if given ’+//’, will jump to the first different image matching the last given regular expression pattern. Match will occur on both file name and description, eventually loaded via desc or --load-image-descriptions-file.

help
help [{identifier}] : provide online help, assuming {identifier} is a variable, alias, or command identifier. If {identifier} begins with /, the search will be on the help contents and a list of matching items will be given instead. A list of commands can be obtained simply invoking "commands"; a list of aliases with "alias"; a list of bindings with "bind".

if
if(expression){action;}[’else’{action;}] : see if

info
info : display information about the current file

limit
limit [{expression} |{variable} {value}] : A browsable file list filtering function (like limiting in the ’mutt’ program). Uses information loaded via --load-image-descriptions-file. If one argument only is provided, restrict to files whose description string matches {expression}. If two arguments are provided, restrict to files having property {variable} set to {value}. If invoked with one exclamation point (’!’) as argument will restrict to the currently marked files only. Invoked with no arguments, the original browsable files list is restored.

list
list : display the files list; list ’random_shuffle’: randomly shuffle the file list; list ’reverse’: reverse the file list; list ’clear’: clear the file list; list ’sort’: sort the file list; list ’sort_basename’: sort the file list according to the file base name; list ’pop’ : pop the last file from the files list; list ’remove’ [{filename(s)}] : remove the current file, or the {filename(s)}, if specified ; list {filename(s)} ’push’: push {filename(s)} to the back of the files list; list ’filesnum’: display the number of files in the files list; list ’mark’ [{args}] : mark image file names for stdout printing at exit, with {args} mark the ones matching according to the rules of the ’limit’ command, otherwise the current file; list ’unmark’ [{args}] : unmark marked image file names, with {args} unmark the ones matching according to the rules of the ’limit’ command, otherwise the current file; list ’marked’: show which files have been marked so far; list ’pushdir; {dirname}: will push all the files in {dirname}, when matching the regular expression in variable _pushdir_re or, if empty, from constant regular expression .JPG$|.PNG$|.GIF$|.BMP$|.TIFF$|.TIF$|.JPEG$|.JFIF$|.PPM$|.PGM$|.PBM$|.PCX$; list ’pushdirr’ {dirname}: like pushdir, but will also push encountered directory entries recursively.

popen
popen {syscmd} : pipe a command, invoking popen(): spawns a shell, invoking {syscmd} and executing as fim commands the output of {syscmd}

pread
pread {args} : execute {args} as a shell command and read the output as an image file (using popen)

unbind
unbind {keysym} : unbind the action associated to a specified {keysym}; if {keysym} is at least two characters long and begins with 0 (zero), the integer number after the 0 will be treated as a raw keycode to bind the specified {keysym} to. activate the _verbose_keys variable to discover (display device dependent) raw keys.

while
while(expression){action;} A conditional cycle construct. May be interrupted by hitting the Esc or the : key

window

VARIABLES REFERENCE

If undeclared, a variable will evaluate to 0.

There namespaces in which variables may exist are: current image, global. A namespace is specified by a prefix, which is one of: ’i:’, which shall be prepended to the variable name. The global namespace is equivalent to the empty one:’’. The special variable i:* expands to the collation of all the name-value pairs for the current image.

In the following, the [internal] variables are the ones referenced in the source code (not including the hardcoded configuration, which may be inspected and/or invalidated by the user at runtime).

_info_fmt_str [in,g:] custom info format string, displayed in the lower right corner of the status bar; may contain ordinary text and special ’expando’ sequences. These are: %p for current scale, in percentage; %w for width; %h for height; %i for image index in list; %l for image list length; %L for flip/mirror/orientation information; %P for page information; %F for file size; %M for screen image memory size; %m for memory used by mipmap; %C for memory used by cache; %T for total memory used (approximation); %R for total max memory used (as detected by getrusage()); %n for the current file path name; %N for the current file path name basename; ; %c for centering information; %v for the fim program/version identifier string; %% for an ordinary %. A sequence like %?VAR?EXP? expands to EXP if i:VAR is set; EXP will be copied verbatim except for contained sequences of the form %:VAR:, which will be expanded to the value of variable i:VAR; this is meant to be used like in e.g. ’EXIF_DateTimeOriginal?[%:EXIF_DateTimeOriginal:]?’, where an EXIF-set variable (make sure you have libexif for this) will be used only if present.
_inhibit_display [internal,g:] if 1, will inhibit display
_last_file_loader [out,g:] after each image load, _last_file_loader will be set to the last file loader used
_last_system_output [out,experimental,g:] the standard output of the last call to the system command

_magnify_factor [in,g:] the image scale multiplier used when magnifying images size
_max_cached_images [in,experimental,g:] the maximum number of images after which evictions will be forced. Setting this to 0 (no limits) is ok provided _max_cached_memory is set meaningfully.
_max_cached_memory [in,experimental,g:] the maximum amount of memory (in KiB) at which images will be continued being added to the cache. Setting this to 0 (no limit) will lead to a crash (there is no protection currently).
_max_iterated_commands [experimental,g:] the iteration limit for N in "N[commandname]" iterated command invocations
_no_default_configuration [in,g:] if 0, a default, hardcoded configuration will be executed at startup, after the minimal hardcoded one.

_no_rc_file [in,g:] if 1, the ~/.fimrc file will not be loaded at startup
_open_offset [in,optional,g:,i:] offset (specified in bytes) used when opening a file; [out] i:_open_offset will be assigned to images opened at a nonzero offset
_open_offset_retry [in,optional,g:] number of adjacent bytes to probe in opening the file
_orientation [internal,i:] Orthogonal clockwise rotation (orientation) is controlled by: ’i:_orientation’, ’g:_orientation’ and applied on a per-image basis. In particular, the values of the three variables are summed up and the sum is interpreted as the image orientation. If the sum is 0, no rotation will apply; if it is 1, a single ( 90’) rotation will apply; if it is 2, a double (180’) rotation will apply; if it is 3, a triple (270’) rotation will apply. If the sum is not one of 0,1,2,3, the value of the sum modulo 4 is considered. Therefore, ":i:_orientation=1" and ":i:_orientation=5" are equivalent: they rotate the image one time by 90’.
_preferred_rendering_dpi [in,optional,g:] if >0, pdf, ps, djvu rendering will use this value for a default document dpi (instead of a default value)
_preferred_rendering_width [in,optional,g:] if >0, bit based rendering will use this value for a default document width (instead of a default value)
_push_checks [in,experimental,g:] if 1 (default), will check with stat() existence of input files before push’ing them (set this to 0 to speed up loading very long file lists; in these cases a trailing slash (/) will have to be used to tell fim a pathname is a directory). This only works after initialization (thus, after command line files have been push’ed); use --no-stat-push if you wish to set this to 0 at command line files specification
_push_pushes_dirs [in,g:] if 1, the push command will also accept and push directories (using pushdir)
_pushdir_re [in] regular expression to match against when pushing files from a directory or an archive. By default this is ".JPG$|.PNG$|.GIF$|.BMP$|.TIFF$|.TIF$|.JPEG$|.JFIF$|.PPM$|.PGM$|.PBM$|.PCX$".
_pwd [out,g:] the current working directory; will be updated at startup and whenever the working directory changes
_re_search_opts [in,g:] affects regexp-based searches; if an empty string, defaults will apply; if contains ’i’ (’I’), case insensitive (sensitive) searches will occur; if contains ’b’, will match on basename, if contains ’f’ on full pathname.
_reduce_factor [in,g:] the image scale multiplier used when reducing images size
_retry_loader_probe [in,g:] if 1 and user specified a file loader and this fails, will probe for a different loader
_rows [in,g:] if >0, will set the number of displayed text lines in the console
_save_fim_history [in,g:] if 1 on exit, will save the ~/.fim_history file on exit
_scale_factor_delta [in,g:] value used for incrementing/decrementing the scaling factors
_scale_factor_multiplier [in,g:] value used for scaling up/down the scaling factors
_scale_style [in,g:] if non empty, this string will be fed to the scale command
_screen_height [out] the screen height
_screen_width [out,g:] the screen width
_seek_magic [optional,g:] will seek for a magic signature before opening a file (for now, use like this: fim -c ’_seek_magic=MAGIC_STRING;push file_to_seek_in.ext’ )
_status_line [in,g:] if 1, will display the status bar
_steps [in,g:] the default steps, in pixels, when panning images
_sys_rc_file [in,g:] string with the global configuration file name
_use_exiftool [in,g:] if >0 and supported, exiftool will be used to get additional information. if 1, this will be appened to _comment; if 2, will go to _exiftool_comment
_use_mipmaps [in,g:] if >0, will use mipmaps to speed up downscaling of images (this has a memory overhead equivalent to one image copy); mipmaps will not be cached.
_verbose_errors [in,g:] if 1, will display on stdout internal errors, while parsing commands
_verbose_keys [in,g:] if 1, after each interactive mode key hit, the console will display the hit key raw keycode
_verbosity [in,experimental,g:] program verbosity
_vsteps [in,g:] the default steps, in pixels, when panning images vertically (overrides steps)
_want_autocenter [in,g:] if 1, the image will be displayed centered
_want_exif_orientation [in,g:] if 1, will reorient images using information from EXIF metadata (and stored in in __exif_orientation, __exif_mirrored, __exif_flipped ).
_want_prefetch [in,g:] if 1, will prefetch further files just after display of the first file
_want_sleep_seconds [in,g:] number of seconds of sleep during slideshow mode
_want_wm_caption_status [in,g:] this works only if supported by the display device (currently only SDL). if set to a number that is not 0, will show the status (or command) line in the window manager caption; if set to a non-empty string, will interpret it just as a file info format string (see _info_fmt_str); if empty, will show the program version.

ascale [in,out,i:] the asymmetric scaling of the current image
desaturated [out,i:] 1, if the image is desaturated

CONFIGURATION FILE EXAMPLES

This is the default configuration, as contained in the _fim_default_config_file_contents variable.

# $LastChangedDate: 2016-01-17 22:14:48 +0100 (Sun, 17 Jan 2016) $
# Contents of the default ’fimrc’ file, hardcoded in the fim executable.
# Read the documentation (man fimrc) to discover how to change this default hardcoded file and how to make your own.
# Note that usually a ~/.fimrc file is read after these options take effect, so you could reset all of this with ease.
# Lines beginning with a pound (#) are ignored by fim (they are treated as comments).
#
# Internal variables.
# Some of these variables influence Fim’s behaviour (input variables), some are set by Fim (output variables).
# It is wise the input variables are set at the beginning of the file, so the bottom may issue commands correctly affected by them.

NOTES

This manual page is incomplete: a number of topics, as type conversions, or operator precedence, or exact command usage is left unspecified. The conditions for autocommands triggering are not specified as they should. A formal description of the various one-line commands, as well a more extensive example list is needed. Many of the listed variables are only valid within a namespace, and this shall be documented clearly.

BUGS

The fim language has a number of problems that shall be first documented, then fixed.

NAME

fimgs - poor man’s [http://]PostScript/pdf/dvi/cbr/rar/cbz/zip viewer for the linux framebuffer console

SYNOPSIS

fimgs [ {fimgs-options} ] file [-- [{fim-options}]]

DESCRIPTION

fimgs is a simple wrapper script which takes a PostScript or pdf or .cbr or .rar or .cbz or .zip or .dvi or any of the above prefixed with http:// or https:// or ssh:// as input, renders the pages using ghostscript into a temporary directory and finally calls fim to display them.

In case of compressed archives (in zip or rar formats), the images are decompressed into a directory and displayed using fim. In this latter case, only images contained in the archive will be displayed (no nested archives or pdf’s or ps’s or dvi’s).

The temporary directory name is taken from the $TMPDIR environment variable.

OPTIONS

To pass through options to fim, you may specify them after "--".

-r {resolution} Specify resolution for the ’gs’ -r option (e.g.: 96x96; default 120x120).

-p {password}

Specify password for the ’gs’ -p (password) option.
