Fim (Fbi IMproved) aims to be a highly customizable and scriptable image viewer targeted at the users who are confortable with software like the Vim text editor or the Mutt mail user agent.
The application is based on the Fbi image viewer and works in the Linux framebuffer console (it is not an X program). It features the ability to filter the list of images with regular expressions, Vim-like autocommands, command line autocompletion and history, completely customizable key bindings, external/internal scriptability, and much more.
Main features:

- every possible internal action has a textual command name
- on-screen debug and information console in command mode
- command line history
- command line tab-based command autocompletion (thanks to the readline)
- command line command autocompletion (optional)
- key-action binding, with SHIFT and CONTROL key combinations
- simple if-while scriptability, with integer,float,and string variables and arithmetic evaluation
- command aliases support (macros)
- event autocommands (in Vims autocmd style)
- regular expressions to enrich autocommand behaviour
- configuration (initialization) file support
- usable builtin default configuration
- wrapper script to convert pdf,ps,eps,dvi,cbr(rar),cbz(zip),tar,tar.gz,tgz
- contents into images and display with Fim
- index based goto
- regular expressions (on filename) based goto
- stuff usual for an image viewer (scale, pan, etc..)
- stuff (un)usual for an image viewer (setting scale factor, auto width scale,
- auto heigth scale, marking of interesting files, sorting of files in the
- list, recording/replaying of sessions, repeat last action )
- script file execution
- system call
- pipe with some input program
- these features could be enabled or disabled at compile time editing the Makefile

Image::BMP is a bitmap parser/viewer.
SYNOPSIS
use Image::BMP;
# Example one:
my $img = new Image::BMP(
file => some.bmp,
debug => 1,
);
$img->view_ascii;
# Example two:
my $img2 = new Image::BMP;
$img2->open_file(another.bmp);
my $color = $img2->xy(100,100); # Get pixel at 100,100
my ($r,$g,$b) = $img2->xy_rgb(100,200);
Image::BMP objects can parse and even ascii view bitmaps of the .BMP format. It can read most of the common forms of this format.
It can be used to:
Just get image info, dont read the whole image:
my $img = new Image::BMP(file => some.bmp);
print "Resolution: $img->{Width} x $img->{Height}n";
View images
(See C< SYNOPSIS > example one)
Read images and poke at pixels
(See C< SYNOPSIS > example two)
Parse through all pixel data
(See C< ADD_PIXEL > below)
It does not currently write bmap data, simply because I didnt have a use for that yet. Convince me and Ill add it.
Version restrictions:
4-bit RLE compression
- I havent seen an image like this yet, it wouldnt be hard to add.
bitfields compression
- I dont even know what that is..
RLE delta compression
- This isnt tested yet - I havent seen an image that uses this portion of RLE compression, so it currently does what I think is right and then prints a message asking you to send me the image/results.
