Image Magazine provides a content type which acts both as a folder and as an image.
You populate it with 2 to 4 images, and optionnaly select a layout.
Options include width, background color, padding and margin, and layout mode.
ImageMag then merges the images into a layout while keeping the aspect ratios.
You can then use and call your ImageMag as a standard ploneImage, this mean you can :
.use instance/image_thumbnail, instance/image_large, and so on suffixes to call its different sizes
.call it directly from kupu to illustrate your articles (see readme.txt)
Works with:
- Plone 2.5.2
- Plone 2.5.1
- Plone 2.5

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 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.

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).

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.

QVV is image viewer based on TrollTechs Qt Toolkit! QVV is small, simple, handy ( last one is IMO ). However the sources are there -- you can come up with your own opinion.

NOTE: QVV 0.16 AND LATER VERSIONS REQUIRE QT 3.x!

QVV allows you to browse directories with lynx-like interface, view images browse next/prev image while showing image window or in the directory list, multiple image windows and directory browsers can be opened/closed with a single key, panning easy with arrow keys or mouse and few other things as well.

QVV is only few hundred lines of source code and handles as much file formats as Qt does -- JPEG (all sorts of jpegs that jpeglib supports), PNG, GIF, XPM and more..

Image rotator can be used to automatically detect and rotate landscape/portrait photos from digital cameras.
Currently, only outdoor photos are recognized. Image rotator is a command line tool which uses an artifical neural network to detect the orientation of images. Image reading, scaling, and rotation are done with the ImageMagick library.
Enhancements:
- The --verify option can now be used to decrease the number of false decisions.
- This is done by running the image three times (original, rotated left, rotated right) through the neural network.
- A small memory leak was fixed.
