image-viewer is a very simple Kommander script. But written following one of the 2-3 tutorials you can find on the net. Included in tarball you can find this guide to introduce in Kommander GUI. The site is: http://applications.linux.com/article.pl?sid=04/12/17/2033227&tid=49 and was written in 2004 by Michał Kosmulski

I know people want to use this great program..but documentations are very poor...this example helps people who wants to learn something about simple array, combobox, label and connections between signals and slots..very very important.

So, i hope the guide and the example will be usefull.

Image::Xpm is a Perl module that can load, create, manipulate and save xpm image files.

SYNOPSIS

use Image::Xpm;

my $j = Image::Xpm->new(-file, Camel.xpm);

my $i = Image::Xpm->new(-width => 10, -height => 16);

my $h = $i->new; # Copy of $i

$i->xy(5, 8, red); # Set a colour (& add to palette if necessary)
print $i->xy(9, 3); # Get a colour

$i->xy(120, 130, #1256DD);
$i->xy(120, 130, $i->rgb2colour(66, 0x4D, 31));

$i->vec(24, #808080); # Set a colour using a vector offset
print $i->vec(24); # Get a colour using a vector offset

print $i->get(-width); # Get and set object attributes
$i->set(-height, 15);

$i->load(test.xpm);
$i->save;

# Changing just the palette
$i->add_colours(qw(red green blue #123456 #C0C0C0));
$i->del_colour(blue);

This class module provides basic load, manipulate and save functionality for the xpm file format. It inherits from Image::Base which provides additional manipulation functionality, e.g. new_from_image(). See the Image::Base pod for information on adding your own functionality to all the Image::Base derived classes.

new()
my $i = Image::Xpm->new(-file => test.xpm);
my $j = Image::Xpm->new(-width => 12, -height => 18);
my $k = $i->new;

We can create a new xpm image by reading in a file, or by creating an image from scratch (all the pixels are white by default), or by copying an image object that we created earlier.

If we set -file then all the other arguments are ignored (since theyre taken from the file). If we dont specify a file, -width and -height are mandatory and -cpp will default to 1 unless specified otherwise.

-file

The name of the file to read when creating the image. May contain a full path. This is also the default name used for loading and saveing, though it can be overridden when you load or save.

-width

The width of the image; taken from the file or set when the object is created; read-only.

-height

The height of the image; taken from the file or set when the object is created; read-only.

-cpp

Characters per pixel. Commonly 1 or 2, default is 1 for images created by the module; read-only.

See the example for how to change an images cpp.

-hotx

The x-coord of the images hotspot; taken from the file or set when the object is created. Set to -1 if there is no hotspot.

-hoty

The y-coord of the images hotspot; taken from the file or set when the object is created. Set to -1 if there is no hotspot.

-ncolours

The number of unique colours in the palette. The image may not be using all of them; read-only.

-cindex

An hash whose keys are colour names, e.g. #123456 or blue and whose values are the palette names, e.g. , #, etc; read-only. If you want to add more colours to the image itself simply write pixels with the new colours using xy; if you want to add more colours to the palette without necessarily using them in the image use add_colours.

-palette

A hash whose keys are the palette names, e.g. , #, etc. and whose values are hashes of colour type x colour name pairs, e.g. c => red, etc; read-only. If you want to add more colours to the image itself simply write pixels with the new colours using xy; if you want to add more colours to the palette without necessarily using them in the image use add_colours.

-pixels

A string of palette names which constitutes the data for the image itself; read-only.

-extname

The name of the extension text if any; commonly XPMEXT; read-only.

-extlines

The lines of text of any extensions; read-only.

-comments

An array (possibly empty) of comment lines that were in a file that was read in; they will be written out although we make no guarantee regarding their placement; read-only.
get()

my $width = $i->get(-width);
my ($hotx, $hoty) = $i->get(-hotx, -hoty);

Get any of the objects attributes. Multiple attributes may be requested in a single call.

See xy and vec to get/set colours of the image itself.

set()
$i->set(-hotx => 120, -hoty => 32);

Set any of the objects attributes. Multiple attributes may be set in a single call; some attributes are read-only.

See xy and vec to get/set colours of the image itself.

xy()
$i->xy(4, 11, #123454); # Set the colour at point 4,11
my $v = $i->xy(9, 17); # Get the colour at point 9,17

Get/set colours using x, y coordinates; coordinates start at 0. If the colour does not exist in the palette it will be added automatically.

When called to set the colour the value returned is characters used for that colour in the palette; when called to get the colour the value returned is the colour name, e.g. blue or #f0f0f0, etc, e.g.

$colour = xy($x, $y); # e.g. #123456
$cc = xy($x, $y, $colour); # e.g. !

We dont normally pick up the return value when setting the colour.

vec()
$i->vec(43, 0); # Unset the bit at offset 43
my $v = $i->vec(87); # Get the bit at offset 87

Get/set bits using vector offsets; offsets start at 0. The offset of a pixel is ((y * width * cpp) + (x * cpp)).

The sort of return value depends on whether we are reading (getting) or writing (setting) the colour - see xy for an explanation.

rgb2colour() and rgb2color()
$i->rgb2colour(0xff, 0x40, 0x80); # Returns #ff4080
Image::Xpm->rgb2colour(10, 20, 30); # Returns #0a141e

Convenience class or object methods which accept three integers and return a colour name string.

load()
$i->load;
$i->load(test.xpm);

Load the image whose name is given, or if none is given load the image whose name is in the -file attribute.

save()
$i->save;
$i->save(test.xpm);

Save the image using the name given, or if none is given save the image using the name in the -file attribute. The image is saved in xpm format.

add_colours() and add_colors()
$i->add_colours(qw(#C0C0DD red blue #123456));

These are for adding colours to the palette; you dont need to use them to set a pixels colour - use xy for that.

Add one or more colour names either as hex strings or as literal colour names. These are always added as type c colours; duplicates are ignored.

NB If you just want to set some pixels in colours that may not be in the palette, simply do so using xy since new colours are added automatically.

del_colour() and del_color()
$i->del_colour(green);

Delete a colour from the palette; returns undef if the colour isnt in the palette, false (0) if the colour is in the palette but also in the image, or true (1) if the colour has been deleted (i.e. it was in the palette but not in use in the image).

Partition Image application is a Linux/UNIX utility which saves partitions in many formats (see below) to an image file.
The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable floppies (ZIP for example); partitions can be saved across the network since version 0.6.0.
Partition Image will only copy data from the used portions of the partition. For speed and efficiency, free blocks are not written to the image file.
This is unlike the dd command, which also copies empty blocks. Partition Image also works for large, very full partitions. For example, a full 1 GB partition can be compressed with gzip down to 400MB.
This is very useful to save partitions to an image in some cases:
- First you can restore your linux partition if there is a problem (virus, file system errors, manipulation error) . When you have a problem, you just have to restore the partition, and after 10 minutes, you have the original partition. You can write the image to a CD-R if you dont want the image to use hard-disk space.
- This utility can be used to install many identical PCs. For example, if you buy 50 PCs, with the same hardware, and you want to install the same linux systems on all 50 PCs, you will save a lot of time. Indeed, you just have to install on the first PC and create an image from it. For the 49 others, you can use the image file and Partition Images restore function.
