Free thumbnail software for linux

GD::Thumbnail is a thumbnail maker for GD.

SYNOPSIS

use GD::Thumbnail;
my $thumb = GD::Thumbnail->new;
my $raw = $thumb->create(test.jpg, 80, 2);
my $mime = $thumb->mime;
warn sprintf "Dimension: %sx%sn", $thumb->width, $thumb->height;
open IMG, ">thumb.$mime" or die "Error: $!";
binmode IMG;
print IMG $raw;
close IMG;
or
use CGI qw(:standard);
use GD::Thumbnail;
my $thumb = GD::Thumbnail->new;

my $mime = $thumb->mime;
binmode STDOUT;
print header(-type => "image/$mime");
print $raw;

This a thumbnail maker. Thumbnails are smaller versions of the original image/graphic/picture and are used for preview purposes, where bigger images can take a long time to load. They are also used in image galleries to preview a lot of images at a time.

This module also has the capability to add information strips about the original image. Original images size (in bytes) and resolution & mime type can be added to the thumbnails upper and lower parts. This feature can be useful for web software (image galleries or forums).

This is a Yet Another type of module. There are several other thumbnail modules on CPAN, but they simply dont have the features I need, so this module is written to increase the thumbnail population on CPAN.

The module can raise an exception if something goes wrong. So, you may have to use an eval block to catch them.

GD::Image::Thumbnail is a Perl extension for creating thumbnailed images with GD.

SYNOPSIS

use GD::Image::Thumbnail;

my $img = GD::Image->new(100,20);

my $thm = $img->thumbnail; # same as { factor => 0.20 }
my $thm = $img->thumbnail($n); # same as { side => $n }

my $thm = $img->thumbnail({ factor => 0.25 });
my $thm = $img->thumbnail({ factor => 0.25, small => 1 });

my $thm = $img->thumbnail({ side => $n });
my $thm = $img->thumbnail({ side => $n, small => 1 });

my $thm = $img->thumbnail({ w => $w });
my $thm = $img->thumbnail({ h => $h });
my $thm = $img->thumbnail({ w => $w, h => $h });

my $thm = $img->thumbnail({ w => $w, small => 1 });
my $thm = $img->thumbnail({ h => $h, small => 1 });
my $thm = $img->thumbnail({ w => $w, h => $h, small => 1 });
thumb() ^
thumb() is shortcut for thumbnail() - useful for people who like to bite their nails :)
$img->thumbnail(@thm_args)
and
$img->thumb(@thm_args);
are doing the same thing

OPTIONS

factor => $n

This makes a thumbnail $n (0.20 by default) times the size of the original. Only a two decimal place number between 0 and 1 are allowed. If a factor is given side, h, and w are all ignored

side => $n

Makes the side that will result in a larger thumbnail $n pixels (or opposite if small => 1). If side is given then h and w are ignored.

w => $x and h => $y

You can specify one or both of these. If only one is given it makes that side that dimention. If you specify both, the side that will result in a larger thumbnail (based on the images orientation and *not* the values of w and h if different), is used (or opposite if small => 1).

small => 1

If true make the images the smallest possible. This will round down instead of up when rounding is necessary and will help decide which side gets set to the given value.

$img->thumbnail(10); # 100 x 25 image becomes 40 x 10
$img->thumbnail({ side => 10, small => 1}); # 100 x 25 image becomes 10 x 2
resample => 1

If true use copyResampled() instead of copyResized() See GDs documentation about the difference. This can also be turned on by specifying a true value as the second argument:

$img->thumbnail($n, 1);
$img->thumbnail({ factor => $n }, 1);

Thumbs is a Firefox extension that shows the first thumbnail from each linked gallery. After installing, use Customize Toolbars to add the Thumbs toolbar button, or select some links and right-click.

The Options window requires Firefox 1.5 Beta; it doesnt work in Firefox 1.0.x. Everything else should work, and you can still use about:config to tweak the options if want.

Fetchgals is a Web spider that locates and optionally downloads free pictures and movies from the internet.

Today, commercial porn sites are advertised like this: somebody puts together a thumbnail gallery, i.e. a web page with small thumbnail pictures linking to free full-size images or movies, and provides a link to the pay site. These thumbnail galleries are listed on central websites called Thumbnail Gallery Posts (TGPs). Unfortunately, many TGPs add a layer of redirects, popups, spyware and viruses. Fetchgals is designed to eliminate the TGP.

The fetchgals distribution comes with a huge list of TGPs. This list was generated by a separate script called findtgps, which is also included in the distribution. Fetchgals visits these TGPs in order to locate thumbnail galleries. The images and movies of these galleries can then be downloaded. Since theres a couple hundred gigabytes of free porn on the internet at any given time, fetchgals constantly monitors local disk space to avoid overruns. Alternatively, fetchgals can create local HTML pages that link to the known galleries; this minimizes disk and bandwidth usage.

The script is written in perl and uses multiple threads to maximize throughput. Both fetchgals and findtgps are in the public domain.

MPlayerThumbs for Kubuntu is a thumbnail generator for video files on Konqueror.

Unlike the original konqueror plugin (in my gentoo box is artsplugin-xine), it DOESNT depend neither on xine nor arts, instead it uses only mplayer.

You can take advantage of this on x86_64 systems, where you can use a 32bit mplayer to load win32codecs. To configure the location of your mplayer binary launch mplayerthumbsconfig.

Also its faster than the xine plugin, since it can seek and play only a limited number of frames.

MPlayerThumbs for Kubuntu catches a random frame from 15% to 70%, checking also how contrasted is the image, and dropping bad frames.

Photo Novilab provides a Web image gallery generation program.

Photo Novilab is an highly customizable program written in PHP that lets you create photo galleries on your Web site simply by uploading the images.

It creates a thumbnail gallery and has the capability to insert a button to send the photo link by email.

It also features the ability to view how many times a picture has been viewed.

v Every picture is published along with the text sent from the mobile phone.
Main features:
- POP3 support
- STDIN support (when piped directly from sendmail)
- image pagination with a configurable number of columns and images per page
- an image rotation function via the Web
- photo tag editing via the Web
- automatic thumbnail generation
- a user access log with originating IP and network display (php-whois required)
- user account maintenance via the Web
- a photo search function
- multi-language support
- EXIM support (for extracting the real picture date and time).

Emblems Hack is a simple hack to kdelibs-3.5.5 (and 3.5.6) that adds basic emblem support, like in GNOME. (It doesnt use the same format, though.)

There is currently no GUI to select emblems for files, so to set an emblem, run this command: attr -s emblem -V icon-name file

icon-name can be either a valid KDE icon name or an absolute path (e.g. /home/user/icon.png).

Currently, emblems are not drawn on thumbnail previews. Ill attempt to fix this in the next version.
