Free graphic library software for linux

Gd is a graphics library. It allows your code to quickly draw images complete with lines, arcs, text, multiple colors, cut and paste from other images, and flood fills, and write out the result as a PNG or JPEG file. This is particularly useful in World Wide Web applications, where PNG and JPEG are two of the formats accepted for inline images by most browsers.

In gd 1.0, it stood for "gif draw." After the Unisys patent on the LZW compression used in GIF came to light and GIF support was dropped, it did not officially stand for anything, but lets just say "graphics draw" and leave it at that. (GIF support is back, thanks to the expiration of the patent, but gd can draw much more than GIFs.)

This is a quick install guide:

1. Type ./configure
2. Type make install

GOBLIN is a C++ class library focussed on graph optimization and network programming problems. GOBLIN Graph Library deals with all of the standard graph optimization problems discussed by textbooks and in courses on combinatorial optimization.
This software package also consists of a shell interpreter which extends the well-known Tcl/Tk language to graph objects and a graph browser and editor tool. Executable solvers are available for practical optimization problems. The graph browser applies for teaching and scientific documentation purposes.
GOBLIN is open source software and licenced by the GNU Lesser Public License (LGPL). That is, GOBLIN may be downloaded, compiled and used for scientific, educational and other purposes free of charge. For details, in particular the statements about redistribution and changes of the source code, observe the LGPL document which is attached to the package.
Main features:
- The gosh interpreter extends the Tcl/Tk scripting language to graph objects in a natural way.
- The goblet graph browser and editor tool. Graphical front end to the library.
- An open class hierarchy which strictly separates between abstract classes (all mathematical algorithms are defined as methods of abstract classes), implementations (i.e. by incidence lists, adjacency matrices) and logical views (problem transformations).
- A generic branch and bound module with several applications to graph optimization.
- Logging and tracing functionality which allows to study the various algorithms by examples.
- A runtime configuration module controls the selection of mathemetical methods, logging information, and the tracing of data objects.
- Compile time configuration module for code optimization.
- A file interface which can be easily extended to new problem classes.
- Source code for executable solver programs.
Today, GOBLIN provides strongly polynomial algorithms for the following graph optimization problems:
- Shortest paths in graphs and digraphs with negative lengths.
- Negative cycles and minimum mean cycles.
- Strong and 2-connected components.
- Minimum spanning trees, arborescences and 1-trees.
- Maximum st-flows, feasible circulations and b-flows.
- Min-cost st-flows, b-flows and circulations.
- Assignment problems of any kind.
- 1-matchings, b-matchings, capacitated b-matchings, f-factors and degree-constrained subgraphs.
- Directed and undirected Chinese postman problems, T-joins.
Enhancements:
- This release comes with explicit code for orthogonal drawing of trees.
- There are also new generator methods for regular planara graphs.
- A lot of doxygen comments has been added, but dexcription are still far from complete.

FF RADIUS Library is a C library that implements some parts of RFCs 2865 and 2866 to provide a RADIUS implementation.
Youre welcome to modify/enhance it! Please let me know of any further developments, in order for me to include/link them.
Enhancements:
- A segfault was fixed in makeMD5().

Fid Core Library is the core library for the Frigand Imperial Desktop, a genuine Unix desktop environment based around multiprocessing, text-stream IPC, and the "everything is a file" concept.
It supports Emacs-like extensibility, customizability, and built-in multi-buffer support.
Enhancements:
- This release adds testing support for the axioms over buffer implementations and user interfaces, a better implementation of interactive, and a new cursor movement mechanism that allows the user interface to manage point itself (and, hence, keep it always on a widget).

AA Helper Library is a basic library of helper functions for AAlib.

Inspiration that started this is AAJM, when I implemented circles and lines. More or less on a whim, I turned it into a more convincing project.

Yes, Im fully aware of the existence of libcaca. A few things:

1. Libcacas picture definition isnt as good as aalibs - as the designer of libcaca stated, its designed to make colors work right on ascii displays, rather than necessarily the shapes. For a simple example of this, run cacafire next to aafire on a screen at the same time

2. AA Helper addresses most of libcacas other good points - sprites and graphics primitives, primarily

3. If youre at the point where you feel the urge to even start this argument, youve got bigger issues than whether or not a text-mode library is as good as another

asio is a cross-platform C++ library for network programming that provides developers with a consistent asynchronous I/O model using a modern C++ approach.

asio is released under the Boost Software License.

Java DIME Library project implements Direct Internet Message Encapsulation (DIME), which is a lightweight binary encapsulation format that can be used to encapsulate multiple payloads of arbitrary types and sizes into a single message.
DIME is ideal for incorporating binary attachments into any XML-based protocol. The library fully supports the latest DIME specifications.
Enhancements:
- Corrected DimeRecord.isFirst() thanks to John Russell

TCB::Library provides a database-backed book library package for DBIx::Frame.

TCB::Library is a DBIx::Frame object written to keep track of library books at the TCB Group at UIUC.

It provides a Web interface for adding books to the library, for users to check out and return them, and for reminder messages to be sent out periodically to list what books are checked out.

This is actually a fairly basic function of research groups, but doesnt have a standard software package.
