FBGAMMA
This variable may be used to specify a default gamma correction.
Linux framebuffer imageviewer
fbi [options]
file ...
Fbi displays the specified file(s) on the linux console using the framebuffer device. PhotoCD, jpeg, ppm, gif, tiff, xpm, xwd, bmp, png and webp formats are supported natively. For other fbi tries to use ImageMagick(1)´s convert(1).
-h, --help
Print usage info.
-V, --version
Print fbi version number.
--store
Write command line arguments to config file ~/.fbirc.
-l file, --list fileRead image filelist from file.
-P, --text
Enable textreading mode. In this mode fbi will display large images without vertical offset (default is to center the images). The SPACE command will first try to scroll down and go to the next image only if it is already on the bottom of the page. Useful if the images you are watching are text pages, all you have to do to get the next piece of text is to press space...
-a, --autozoom
Enable autozoom. Fbi will automagically pick a reasonable zoom factor when loading a new image.
--(no)autoupLike autozoom, but scale up only.
--(no)autodownLike autozoom, but scale down only.
--(no)fitwidthUse width only for autoscaling.
Be verbose: enable status line on the bottom of the screen (enabled by default).
Randomize the order of the filenames.
--(no)commentsDisplay comment tags (if present) instead of the filename. Probably only useful if you added reasonable comments yourself (using wrjpgcom(1) for example), otherwise you likely just find texts pointing to the software which created the image.
Enable editing commands.
--(no)backupCreate backup files (when editing images).
Preserve timestamps (when editing images).
--(no)readaheadRead ahead images into cache.
--cachemem sizeImage cache size in megabytes (default is 256).
--blend timeImage blend time in miliseconds.
-T n, --vt nStart on virtual console n.
-s steps, --scroll stepsSet scroll steps in pixels (default is 50).
-t sec, --timeout secStart a continuous slideshow where each image is loaded at sec second intervals without any keypress.
Don't loop (only use with -t).
-r n, --resolution nSelect resolution, n = 1..5 (default is 3, only PhotoCD).
-g n, --gamma nGamma correction. Requires Pseudocolor or Directcolor visual, doesn't work for Truecolor (default is 1).
-f <arg>, --font <arg>Set font. This <arg> can be anything fontconfig accepts (see fonts-conf(5)). Try fc-list(1) for a list of known fonts on your system. The fontconfig config file is evaluated as well, so any generic stuff defined there (such as mono, sans) will work as well. It is recommended to use monospaced fonts, the textboxes (help text, exif info) look better then.
-d /dev/fbN, --device /dev/fbNUse /dev/fbN device framebuffer. Default is the one your virtual console is mapped to.
-m videomode, --mode videomodeName of the video mode to use (video mode must be listed in /etc/fb.modes). Default is not to change the video mode.
--(no)interactiveAllow interactively controlling the program from the keyboard. This requires that stdin is a TTY. Default is to allow interactive control.
Fbi uses the following environment variables:
FBGAMMA
This variable may be used to specify a default gamma correction.
The commands take effect immediately; it is not necessary to type a carriage return.
In the following commands, i is a numerical argument.
|
Scroll large images. |
|---|---|
|
Previous image. |
|
Next image. |
i
|
Jump to image #i. |
RETURN
|
Write the filename of the current image to stdout(3), then go to the next image. |
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:
fbi file1.gif file2.jpg file3.jpg > fileimagelist.lst
some RETURN and SPACE...
fbi -l fileimagelist.lst
|
Autozoom. |
|---|---|

|
In. |
|
Out. |
i
|
Set zoom to i%. |
ESQ,
|
Quit. |
|---|---|
|
Toggle status line. |
|
Display textbox with brief help. |
|
Display textbox with some EXIF info. |
|
Pause the slideshow (if started with |
Fbi also provides some very basic image editing facilities. You have to start fbi with the -e switch to use them.
D,
|
Delete image. |
|---|---|
|
Rotate 90 degrees clockwise. |
|
Rotate 90 degrees counter-clock wise. |
|
Mirror image vertically (top / bottom). |
|
Mirror image horizontally (left to right). |
The delete function actually wants a capital letter D, thus you have to type Shift+d. This is done to avoid deleting images by mistake because there are no safety bells: If you ask fbi to delete the image, it will be deleted without questions asked.
The rotate function actually works for JPEG images only. It does a lossless transformation of the image.
