The Graphics Transformation Languages is a set of libraries for using and
integrating transformation algorithms (such as filter or color conversion) in
graphics applications.
The goal is to provide the tools, languages and libraries to create generic
transformation for graphics. Those transformations could then be used by
different programs (Krita, The Gimp, CinePaint, gegl...).
Currently the focus is on developing two languages, designed for two different
implementations.
- OpenCTL which is a GPL compatible of the Color Transformation Language, this
language is dedicated at transforming the value of a single pixel (for
instance brightness adjustement or desaturate). CTL is designed to be part of
the Color Management process.
- OpenShiva is inspired by Adobe's Hydra language from the AIF Toolkit, Shiva
is a language that apply a kernel-like transformations on an image, that means
it works using more than one pixel.
This is a low level console graphics library, originally based on VGAlib 1.2
by Tommy Frandsen. VGAlib supported a number of standard VGA graphics modes,
as well as high resolution/high color modes found on many popular graphics
adapters. As of now, support for many more chipsets had been added.
It supports transparent virtual console switching, that is, you can switch
consoles to and from text and graphics mode consoles using Alt-[Function
Key]. Also, SVGAlib corrects most of VGAlib's textmode corruption behavior
by catching SIGSEGV, SIGFPE, SIGILL, and other fatal signals and ensuring
that a program is running in the currently visible virtual console before
setting a graphics mode.
This meta-port installs the graphics and image manipulation components
of KDE 4.
The Progressive Graphics File (PGF) is an efficient image file format that is
based on a fast, discrete wavelet transform with progressive coding features.
PGF can be used for lossless and lossy compression.

GD.pm is a Perl interface to Thomas Boutell's gd graphics library
(version 2.01 or higher). GD allows you to create color drawings
using a large number of graphics primitives, and emit the drawings
as PNG files.
ggplot2 is a plotting system for R, based on the grammar of graphics,
which tries to take the good parts of base and lattice graphics and
none of the bad parts. It takes care of many of the fiddly details
that make plotting a hassle (like drawing legends) as well as
providing a powerful model of graphics that makes it easy to produce
complex multi-layered graphics.
Cenon is a graphical tool of a special kind. Build upon a modular graphical
core, Cenon offers a wide variety of possibilities and applications. The
best of all, Cenon is free software, available with full source codes, and
at home on many computer platforms. It can be used for (including, but not
limited to):
* Desktop Publishing
* Vector Graphics Conversion (quite a few formats supported)
* CAM and PCB-Prototyping (via commercial module)
* Astrology (via free module)
