Free default image software for linux

create Image is an amarok script that can create an image of the current playlist and save the files to an iso image.

The iso image is found in the respective home folders.

GD::SecurityImage is a security image (captcha) generator.

SYNOPSIS

use GD::SecurityImage;

# Create a normal image
my $image = GD::SecurityImage->new(width => 80,
height => 30,
lines => 10,
gd_font => giant);
$image->random($your_random_str);
$image->create(normal => rect);
my($image_data, $mime_type, $random_number) = $image->out;
or
# use external ttf font
my $image = GD::SecurityImage->new(width => 100,
height => 40,
lines => 10,
font => "/absolute/path/to/your.ttf",
scramble => 1);
$image->random($your_random_str);
$image->create(ttf => default);
$image->particle;
my($image_data, $mime_type, $random_number) = $image->out;

or you can just say (most of the public methods can be chained)

my($image, $type, $rnd) = GD::SecurityImage->new->random->create->particle->out;

to create a security image with the default settings. But that may not be useful. If you require the module, you must import it:

require GD::SecurityImage;
GD::SecurityImage->import;

The module also supports Image::Magick, but the default interface uses the GD module. To enable Image::Magick support, you must call the module with the use_magick option:

use GD::SecurityImage use_magick => 1;

If you require the module, you must import it:

require GD::SecurityImage;
GD::SecurityImage->import(use_magick => 1);

The module does not export anything actually. But import loads the necessary sub modules. If you don t import, the required modules will not be loaded and probably, youll die().

The (so called) "Security Images" are so popular. Most internet software use these in their registration screens to block robot programs (which may register tons of fake member accounts). Security images are basicaly, graphical CAPTCHAs (Completely Automated Public Turing Test to Tell Computers and Humans Apart). This module gives you a basic interface to create such an image. The final output is the actual graphic data, the mime type of the graphic and the created random string. The module also has some "styles" that are used to create the background (or foreground) of the image.

If you are an Authen::Captcha user, see GD::SecurityImage::AC for migration from Authen::Captcha to GD::SecurityImage.

This module is just an image generator. Not a captcha handler. The validation of the generated graphic is left to your programming taste.

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.

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.
