Free imaging software for linux

HP Linux Imaging and Printing Driver Project consists of two projects:

1) HPIJS, a printer driver for HP devices

2) HP Linux Imaging and Printing (HPLIP), a complete printing and imaging solution for Linux (note: HPLIP includes HPIJS).

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 Assistant is a Firefox extension that launches an image in an external viewer, when user selects the context menu item provided, which is titled "Open Image..." and is located under View Image right-click menu item.

This allows for zooming, printing, and other rich functionality not available in the browser.

Image::Imlib2 is a Perl interface to the Imlib2 image library.

SYNOPSIS

use Image::Imlib2;

# create a new image
my $image = Image::Imlib2->new(200, 200);

# or load an image
$image = Image::Imlib2->load("foo.png");

# Enable the alpha channel support
$image->has_alpha(1);

# set a colour (rgba, so this is transparent orange)
$image->set_color(255, 127, 0, 127);

# draw a rectangle
$image->draw_rectangle(50, 50, 50, 50);

# draw a filled rectangle
$image->fill_rectangle(150, 50, 50, 50);

# draw a line
$image->draw_line(0, 0, 200, 50);

# set quality before saving
$image->set_quality(50);

# save out
$image->save(out.png);

# create a polygon
my $poly = Image::Imlib2::Polygon->new();

# add some points
$poly->add_point(0, 0);
$poly->add_point(100, 0);
$poly->add_point(100, 100);
$poly->add_point(0, 100);

# fill the polygon
$poly->fill();

# draw it closed on image
$image->draw_polygon($poly, 1);

# create a color range
my $cr = Image::Imlib2::ColorRange->new();

# add a color
my ($distance, $red, $green, $blue, $alpha) = (15, 200, 100, 50, 20);
$cr->add_color($distance, $red, $green, $blue, $alpha);

# draw it
my($x, $y, $width, $height, $angle) = (20, 30, 200, 200, 1);
$image->fill_color_range_rectangle($cr, $x, $y,
$width, $height, $angle);

Image::Imlib2 is a Perl port of Imlib2, a graphics library that does image file loading and saving as well as manipulation, arbitrary polygon support, etc. It does ALL of these operations FAST. It allows you to create colour images using a large number of graphics primitives, and output the images in a range of formats.

Image::Imlib2::Polygon and Image::Imlib2::ColorRange are described following Image::Imlib2 but may be referenced before their description.

Note that this is an early version of my attempt at a Perl interface to Imlib2. Currently, the API is just to test things out. Not everything is supported, but a great deal of functionality already exists. If you think the API can be tweaked to be a bit more intuitive, drop me a line!
Note that a development version of Imlib2 must be installed before installing this module.

Image Viewer is an image viewer with real-time interactive pan and zoom viewing that uses the GTK+ toolkit and Imlib (or Imlib2).
Image Viewer can open and save to any image format supported by Imlib, rectangular crop, grab the screen, print, and display on the root window.
Main features:
- View
- Convert
- Grab (Screenshot)
- Print
- Rotate
- Crop
- Resize
- Display on Desktop
Enhancements:
- A bug was fixed in the saving of animated GIF images in which looping was not an option.
- The disposal method support for GIF images was improved.

Resize Image is a service menu which adds the ability to resize an image to a new size.

Requires ImageMagick, KDialog and bash.

Image Tree is a complete and versatile photo publishing system in less than 200 lines of code.

ImgTree is based only on three files:

index php : contains all the php and html code. Must be put, unmodified in every folder of the directory tree.
data.php : contains the specific settings of every folder
style.css : the css style sheet

Every folder of the folder tree must contain the three files. Clearly index.php and style.php should be simply linked:

imgtree/
|-- data.php
|-- index.php
|-- style.css
|-- Section-A
| |-- data.php
| |-- index.php -> ../index.php
| |-- style.css -> ../style.css
| |-- 01-thumb.jpg
| |-- 01.jpg
| |-- 02-thumb.jpg
| |-- 02.jpg
| `-- ...
`-- Section-B
|-- data.php
|-- index.php -> ../index.php
|-- style.css -> ../style.css
|-- 00.jpg
|-- Subsection-B1
| |-- data.php
| |-- index.php -> ../index.php
| `-- style.css -> ../style.css
| |-- cover.jpg
`-- Subsection-B2
|-- data.php
|-- index.php -> ../index.php
|-- style.css -> ../style.css
|-- 01-thumb.jpg
|-- 01.jpg
|-- 02-thumb.jpg
|-- 02.jpg
`-- ...

Every folder act as a section and the behaviour can be choose between:

index : Contains a list of links to every subfolder of the current folder. For every section an image and a description are shown.
thumb : Thumbnails page. Shows every image file of the folder. Thumbnail must be named "xxx-thumb.jpg" for the xxx.jpg file. Ex: 01-thumb.jpg -> 01.jpg ; tramonto-thumb.jpg -> tramonto.jpg ; ecc.
cover : Cover page. Shows an image, a text and an associated link

The file data.php contin the settings specific for every section:

$gallerystart : is the gallery start to generate the back-menu. The path must be relative to the starting folder of the site
$name : name used to link the current section in the menus
$title : page title
$description: description, used as subtitle and for brief description in index pages
$indeximage : image used in index pages to link this section
$type : type of the page (cover|thumb|index)
$imgtitle : associtive array of the images descriptions. Used only by "thumb" pages
$coverimage : image used by "cover" pages
$covertext : text used by "cover" pages
$coverlink= : link used by "cover" pages
$covertitle : title used by "cover" pages

NEEDS a web server (Apache or similar) with PHP support
