Free image collectors software for linux

stic bundles a few Linux tools which are intended to support the task of collecting an unreasonable amount of pictures (preferrably in JPEG format).
similar
a program for detecting duplicate or very similar images. It maintains a
database of characteristic color samples which it compares with submitted
pictures. similar depends on libjpeg and ImageMagick s convert (on a
modern Linux desktop system these components should already be present).
Storage medium may be a usual filesystem or a MySQL database. There
also is a MySQL UDF extension to compare image samples within SQL queries.
similar contains the communications module described at sagent.
simv
a core program to perform file management tasks on an image collection.
Its main purpose is to coordinate file movements with the content of
similars database. This applies to importing new files which get tested
against the existent collection, as well as to inform similar about moving
and deleting files within the collection.
simv depends on an external image viewer like ImageMagick s display
(should already be present on a modern Linux desktop system) or John
Bradleys xv (quite a fast one).
simv contains the communications module described at sagent.
sagent
a standalone version of the communications module used in simv and
similar. This software receives input from its start terminal and multiple
clients, distributes several types of output back to them, and is also
able to act itself as such a client.
Since communications mainly use TCP/IP there is an encryption layer
(Blowfish with 128 bit keys) which provides user authentication. Any
single activity of such a user may be particularly permitted or denied.
Secure connections should be possible that way as long as one can defend
the keyfiles and programs on client and server host against foreign
access.
Front-end connection software is available in C, Tcl/Tk and PHP3 to build
custom clients. In the most primitive case even telnet can act as a
client.
The standalone program sagent may be used as communications node in a tree
of clients. Another purpose is to be a shell frontend which sends commands
to a server and receives its replies.
snntpbatch
a command line based NNTP (newsgroups) client. It is mainly intended for
automatic download of images by use of a filter language. Nevertheless it
also downloads the message texts and converts them to HTML code which
includes the downloaded images. Also, it is capable of automatically
posting sets of images to the newsgroups.
The tools are designed to be very independent of the system flavor. On an
average Linux desktop there should be no need to update existing system
components. Actually one could use stic without having display equipment for
graphics.
Any program activity which is possible in dialog may also be performed in
batch runs. Therefore the tools are quite suitable for users who like to get
boring tasks automated and manual tasks simplified.
All tools code is open source and distributed under BSD license.

Enhancements:
- The new encrypted protocol version 0.2 is standard now : SHA-1 seal, 256 bit keys, variable chaining initialization vector.
- The protocol of a connection is chosen by the client and may or may not be accepted by the server.
- See sagent command -security options clientprotocol , serverprotocol.

Image Repository provides a centralized image repository capable of holding thousands of images with keyword/tag-based browsing.
Image Repository is a centralized image repository capable of holding thousands of images with keyword/tag-based browsing and filtering.
Main features:
- Its goal is to provide you with an easy way to have a centralized image library with thousands of images categorized by keywords, dates, etc.
- It has special handling that lets you browse the keyword space like it was a collection of nested folders. Example: Browse to keyword "Carnivores", you will get the available keywords "Cats", "Dogs", and the selection will narrow down, applying all the keywords you have selected on your path through the keyword space.
- It comes complete with a Kupu "library", meaning you can browse the keywords through the Kupu image insertion dialog to make it easy to locate images even in a large collection of images.
- It has a tagging interface that lets you tag images with a thumbnail like view, and apply keywords to multiple images at once.
- It uses whatever image type you have installed (it does need to be added as an addable type and be able to supply thumbnails like the default Plone image type, though).
Enhancements:
- Added action to register the repository in Kupu. [fschulze]
- Using interfaces, views and adapters in various places to make this more flexible. [fschulze]
- Removed unused code. [fschulze]

ImageConverter is able to convert one image type (example:gif) to another type (example:jpeg).

ImageConverter application uses ImageMagick to conver the images!

DB based NetFLow Collector aims to collect Cisco NetFlow data and store it to a database.
DB based NetFlow Collector has a plugin interface, which makes it flexible for fitting in particular tasks.
Enhancements:
- First release. post your comments/bug reports.

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 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.

Open Media Collectors Database project (OpenDb) is a PHP and MySQL based inventory application that allows you to easily catalog and lend media-related items, including DVD, VCD, CD, VHS, games, books, and laser discs.
There are also quite a few Contributed item types available, and if thats not enough you can define your own.
OpenDb is GPL licenced and built on PHP and MySQL. Anything that you can collect and lend, you can catalog with this system. OpenDb allows you to add new types, by describing them in system database tables designed for the purpose.
It includes workflow mechanism for lending, possibility to use different themes and/or creating themes, retrieving data from Amazon, imdb & others, plugins, language packs, etc.
Main features:
- Catalogue all sorts of things including DVD, (S)VCD, DivX, CD, VHS, Games, Books and Laser Discs
- Lending workflow
- Flexible add of new types
- Themes
- Supports metadata from Amazon, imdb, etc.
- Plugins
- Language Packs

Xenomorph is OpenSource software running on Unix/X11 systems. It provides a unified concept of polynomial and morphologic image filters. It is built for precision, not for speed, that means it works in floating-point mode internally.

It can read PNG, JPG and many other formats, and it writes PNG. A nice feature of this software is its upgradeability by adding new filters. You can learn here how to do this.

The software is built with the Trolltech QT3 widget-set, which means Windows and OSX- versions are possible, but the port would cost money (Trolltech provides his free license for UNIX OpenSource development only) so its not available right now.

Xenomorph is released under the Gnu Public License (GPL), which basically means it is allowed to use and distribute it for free (and only for free).
