Free image server software for linux

IIPImage is an Open Source light-weight client-server system for the remote viewing of very high-resolution images. The project is designed to be bandwidth and memory efficient and usable even over a slow internet connection. The system is fast because the client only needs to download the portion of the whole image that is visible on the screen of the user at their current viewing resolution.
The client requests a view of an image and the server only needs to send back the image tiles necessary for that particular view. This makes it possible to view, navigate and zoom around very large images that would be impossible to download and manipulate on the local machine. It also makes the system very scalable as the image tile downloads will take the same regardless of the size of the source image. In addition, to reduce the bandwidth necessary even further, the tiles sent back are dynamically JPEG compressed with a level of compression that can be optimized for the available bandwidth by the client. In this way it is possible to view extremely large gigapixel images in real-time over the internet.
In order for the system to be as efficient as possible, the images are stored in the multi-resolution TIFF tiled pyramidal format. This allows the server to extract regions of the full image at different resolutions very quickly with little processing overhead. Image of several gigapixels in size can be stored on a central server and viewed by many different users without the need to download large amounts of data.
The system was originally devised by the National Gallery in London and the University of Southampton for the Viseum (1996) and Acohir (1999) EU projects.
The aim of these projects was to create a system for viewing very high resolution colorimetric museum images over the internet. In the case of Acohir, to extend the system to handle 3D object sequences. A published paper describing this work is available online. The current versions of the software, though, have been completely rewritten since then. This kind of system, though, is also applicable to other areas such as geographical informations systems or medical imaging.
Main features:
- Fast lightweight Fast CGI server module that can be embedded in most web servers (Apache, Lighttpd, MyServer etc)
- Several clients available - java applet, javascript etc
- Instant dynamic generation of JPEG overviews or details at any resolution
- Allows easy viewing of extremely large images (gigapixel size) with no significant memory requirements
- Standard TIFF-based image format that can be read by many image processing tools (Photoshop, GIMP, VIPS etc)
- 16 bits per channel image handling
- Greyscale, sRGB and CIE L*a*b* colour spaces
- Panoramic 3D object image sequences
- Secure image distribution: only JPEG-compressed views of the image are sent to the client. The full-resolution image does not need to be accessible
- Example uses: high resolution museum images, geographical information systems, medical imaging etc.
Enhancements:
- The major new feature is a hillshading function for image relief maps.
- In addition, major stability and performance enhancements have been made to the tile cache.
- There has also been a major code cleanup and refactoring to make the core fully modular.

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.

Tigase Server project is a lightweight and scalable Jabber/XMPP server. No third party libraries are needed. For services with very high load and a huge number of users, it can be deployed on as many machines as needed.
Enhancements:
- This release corrects and improves the packet filter, adds a startup script for Mandriva Linux, and fixes a problem with stream initialization on very fast machines.
- The IOService class is now synchronized.
- There are many performance improvements, and processing packets from/to remote servers has been added.

GN gopher server provides a fast gopher and HTTP server.

GN is a fast, light and (for 1995 standards) secure gopher server. An effort is underway to fix the known buffer overflows and bring GN up to par with todays standards.

To use these scripts with the sample sample setup as descibed in the installation guide you need to run mkcache in this (/docs/examples) directory or run mkcache -r in the /docs directory.

To use the image clicking capabilities involving "imagemap" you must get this program from NCSA and compile it. Instructions for setting it up are at

The compiled C program must be renamed imagemap.cgi (or at least something with a suffix .cgi)

Darwin Calendar Server provides a CalDAV server.

The Darwin Calendar Server is a standards-compliant server that allows multiple users to collaboratively share calendaring information. It provides a shared location on the network to store schedules, and allows users to send each other and manage invitations.

In order to provide interoperability with multiple calendaring clients, the server implements the CalDAV protocol, which is an extension of WebDAV, which is in turn an extension of HTTP.

pDonkeyS is Perl implementation of an eDonkey server. The main goal of the server is to provide framework for further eDonkey protocol exploration, but it could be useful in testing of client software, since the server can be configured to output very detailed debugging info about eDonkey traffic.

Image Resize Wizard is a PHP script witch you can add to your web site that enables your visitors to re-size their images quickly and efficiently.
The user just selects their image and the largest side length and click "resize". Image Resize Wizard is very easy to install and can add some very useful functionality to your site.
Main features:
- Image Resize Wizard is easy to install. Just unzip and upload, or if youre using it on a local server, just unzip!
- The Image Resize Wizard interface is as simple as it gets. Just two inputs, a click, and the user gets their image resized.
- No odd libraries needed, the script should work on most servers with PHP installed.
