Free image software for linux

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.

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

Requires ImageMagick, KDialog and bash.

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::ExifTool::QuickTime is a Perl module to read QuickTime and MP4 meta information.

SYNOPSIS

This module is used by Image::ExifTool

This module contains routines required by Image::ExifTool to extract information from QuickTime and MP4 video files.

Mozvert image is a Firefox extension that uses convert from ImageMagick for saving images to its preferred formats.

It adds the entry "Convert Image As..." after "Save Image As..." with 8 predefined formats: PNG, JPG, GIF, XPM, TIFF, BMP, PS (PostScript), XBM, ICO.

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::ParseGIF can parse a GIF image into its compenent parts.

SYNOPSIS

use Image::ParseGIF;

$gif = new Image::ParseGIF ("image.gif") or die "failed to parse: $@n";

# write out a deanimated version, showing only the first frame
$gif->deanimate(0);

# same again, manually printing each part
print $gif->header;
print $gif->part(0);
print $gif->trailer;
# or, without passing scalars around:
$gif->print_header;
$gif->print_part(0);
$gif->print_trailer;


# send an animated gif frame by frame
# - makes for a progress bar which really means something
$gif = new Image::ParseGIF ("progress.gif") or die "failed to parse: $@n";

$gif->print_header;

$gif->print_percent(0.00); # starting...
do_some_work_stage1();

$gif->print_percent(0.10); # 10% complete
do_some_work_stage2();

$gif->print_percent(0.25); # 25% complete
do_some_work_stage3();

$gif->print_percent(0.70); # 70% complete
do_some_work_stage4();

$gif->print_percent(1.00); # done!

$gif->print_trailer;

This module parses a Graphics Interchange Format (GIF) image into its component parts. A GIF is essentially made up of one or more images - multiple images typically are used for animated gifs.

Image::ExifTool is a Perl module that can read and write meta information.

SYNOPSIS

use Image::ExifTool ImageInfo;

# ---- Simple procedural usage ----

# Get hash of meta information tag names/values from an image
$info = ImageInfo(a.jpg);

# ---- Object-oriented usage ----

# Create a new Image::ExifTool object
$exifTool = new Image::ExifTool;

# Extract meta information from an image
$exifTool->ExtractInfo($file, %options);

# Get list of tags in the order they were found in the file
@tagList = $exifTool->GetFoundTags(File);

# Get the value of a specified tag
$value = $exifTool->GetValue($tag, $type);

# Get a tag description
$description = $exifTool->GetDescription($tag);

# Get the group name associated with this tag
$group = $exifTool->GetGroup($tag, $family);

# Set a new value for a tag
$exifTool->SetNewValue($tag, $newValue);

# Write new meta information to a file
$success = $exifTool->WriteInfo($srcfile, $dstfile);

# ...plus a host of other useful methods...

ExifTool provides an extensible set of perl modules to read and write meta information in image, audio and video files, including the maker note information of many digital cameras by various manufacturers such as Canon, Casio, FujiFilm, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Nikon, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Ricoh, Sanyo and Sigma/Foveon.
