Free software library software for linux

Software Render Library is an Open Source software implementation of a polygon-based renderer (like your graphics card).
Main features:
- Transform vertices (from world to screen coordinates)
- Lighting
- Apply fog
- Rasterization of points, lines and triangles
- Texturation
- Z-Buffers
- Alpha blending
- Output to several pixel formats
Installation:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute
`configure itself.
If youre using GNU `make or any other `make program that supports the `VPATH variable, you should instead create a new directory, `cd to it and type `../srlib-src/configure.
This way you can keep the source directory clean and have your sources in a directory which is not modifyable by normal users.
Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Type `make install to install the libraries, headers and documentation. At the moment, only static libraries are built; support for shared libraries will be provided soon.
4. You can remove the library binaries and object files from the build directory by typing `make clean. To also remove the files that `configure created (so you can compile the package for a different kind of computer), type `make distclean.
There is also a `make maintainer-clean target, but that is intended mainly for the packages developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.
Version restrictions:
- Read or write files and file formats, like png or jpeg. Software Render Library expects pixel data in a suitable format in a memory buffer.
- Read and process file formats describing a scene. Software Render Library only takes simple commands like "render this list of triangles" or "apply this certain light".
- Tesselation, i.e. dividing more abstract elements like cubes or spheres into lines and triangles.

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).

Standard Portable Library is a pointer friendly C/C++ STL substitute. The API is similar to Java or .NET and includes common data structures, networking, and database support.

++Skype is a C++ library for skype add-on platform independent software development.
++Skype library is platform independent, easy to use, and easy to extend because of the flexible library design, inspired by modern C++ design ideas.
Performance is one of the goals: only compile-time polymorphism is used. The library license allows you to develop freely redistributed applications without any fee.
Main features:
- Platform independent (Now only linux and windows platforms are supported, but we are looking into the future! Smiling);
- Easy to use;
- Easy to extend because of the flexible library design, inspired by modern C++ design ideas;
- Perfomance was on of our goals - only compile-time polymorphism is used;
- Library license allows you to develop freely redistributed applications without any fee;
- Open source.
Enhancements:
- X11 Protocol support is included in the Linux implementation of the library.
- D-BUS library is no longer a requirement.
- You can remote control Skype via the X11 protocol.

CVS Perl library is a Perl module which is a wrapper around the CVS command with an object-oriented interface.

Installation:

To install this module type the following:

perl Makefile.PL
make
make test
make install

Papyrus is a 2d C++ scenegraph library that utilizes the cairo library to perform drawing operations. In this respect, Papyrus Library is similar to the Gnome::Canvas library.

The initial implementation focuses on function over form, and as a result it should not be considered an optimized run-time library (but it does run reasonably well).

btnSMS Library is a C library that provides an easy interface for sending SMS messages through the Beyond The Net SMS service provider.

Messages can be sent to nearly every country in the world with many different options.

Haru Free PDF library is a free, cross platform, open-sourced software library for generating PDF.
Main features:
- Generating PDF files with lines, text, images.
- Outline, text annotation, link annotation.
- Compressing document with deflate-decode.
- Embedding PNG, Jpeg images.
- Embedding Type1 font and TrueType font.
- Creating encrypted PDF files.
- Using various character set (ISO8859-1~16, MSCP1250~8, KOI-8R).
- Supporting CJK fonts and encodings.
Enhancements:
- fixed a problem of HPDF_Circle() which causes buffer overflow.
- added HPDF_Ellipse().
