fim

NAME

fim - fbi (linux framebuffer imageviewer) improved

SYNOPSIS

fim [ options ] [--] files ...

... | fim [ options ] [--] [ files ] - ...

fim - [ options ] < file_name_list_text_file

fim -i [ options ] < image_file_name

fim -p [ options ] < fim_script_file_name

DESCRIPTION

fim displays the specified file(s) on the linux console using the framebuffer device. jpeg, ppm, gif, tiff, xwd, bmp and png are supported directly. 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'.

Please note that the full documentation of fim is in the FIM.TXT file distributed in the source package. This man page only describes the fim command line switches.

OPTIONS

--

The arguments before -- beginning with - will be treated as command line switches. All arguments after -- will be treated as filenames regardlessly.

-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 pad with zeros. Regard this as a toy..

-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.

-d {device}, --device {device} framebuffer device to use. Default is the one your vc is mapped to (as in fbi).

--dump-reference-help

Will dump to stdout the reference help.

-D, --dump-default-fimrc

The default fimrc file (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 , --etc-fimrc

The /etc/fimrc file will be executed prior to any other configuration file. If not specified, it is *ignored*.

-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

display help and terminate the program.

-i, --image-from-stdin

Will read one single image from the standard input (yes: the image, not the filename). May not work with all supported file formats.

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

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 initialization file will be read (default is ~/.fimrc) at startup.

-p, --script-from-stdin

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

-o {device}, --output-device {device}

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. It will probably be a subset of {sdl, fb, aa, caca, dumb}.

--offset {offset}

Will use the specified offset (in bytes) for opening the specified files (useful for viewing images on damaged file systems).

-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 {n}, --scroll {n}

set scroll steps in pixels (default is 50).

-S, --sanity-check

a quick sanity check before starting fim.

-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.

-v, --verbose

be verbose: show status bar.

-V, --version

display version and compile flags, and then terminate.

-w, --autowidth

Will adapt the image size to the screen size.

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

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).

-

Reads file list from stdin.

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 EXAMPLES below to read some useful (and unique) ways of employing fim.

 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; please see the default fimrc file for examples on this, or read the complete manual: the FIM.TXT file distributed with fim.

AFFECTING ENVIRONMENT VARIABLES

 FBFONT          (just like in fbi) a consolefont or a X11 (X Font Server - xfs) font file.
                         For instance,  /usr/share/consolefonts/LatArCyrHeb-08.psfu.gz is a Linux console file.
                         Consult 'man setfont' for your current font paths.
                         NOTE : Currently xfs is disabled.
 FBGAMMA         (just like in fbi) gamma correction.
 FRAMEBUFFER     (just like in fbi) if set, will override user set framebuffer device file.
 TERM            (only in fim: see the default fimrc) will influence the output device selection algorithm, especially if $TERM=="screen"
 

 

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.

EXAMPLES

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 permuted.

c 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 'm' 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.

BUGS
