appleseed is modern, open source, physically-based rendering engine designed
to produce photorealistic images, animations, and visual effects.
It provides individuals and small studios with an efficient, reliable suite
of tools built on robust foundations and open technologies.
Started in 2009, it has grown into a robust production rendering toolset and
has been battle-tested on several projects such as TV documentaries, ads,
promotional videos, and animation shorts.
ArgyllCMS is an ICC compatible color management system. It supports
accurate ICC profile creation for scanners, cameras and film recorders
and calibration and profiling of displays and RGB & CMYK printers.
Delaboratory is a color correction utility for digital images. It features:
- Floating point precision (not 8-bit like Gimp, not 16-bit like most raw
processors)
- Native support for multiple colorspaces (sRGB, ProPhoto RGB, LAB, CMYK,
LCH, HSL, HSV, BW)
- Non-destructive editing (adjustment layers)
- KISS design, realtime preview
- Basic operations: CMYK curves, CMYK levels, RGB curves, RGB levels,
white balance in LAB, saturation in LAB, LAB curves, BW curve, HSV
equalizer, LCH equalizer, recover shadows/highlights, vignette, local
contrast, LAB/BW/RGB/CMYK gradients
- Expert operations: levels, curves, equalizer, exposure, saturation,
white balance, fill, tone, local contrast, auto_dodge/auto_burn, sharpen,
vignette, gradient, gaussian blur, recover highlights, recover shadows,
channel mixer, high pass, c2g, copy
- Many blend modes (multiply, screen, overlay, inverted overlay, dodge,
burn, add, grain extract, grain merge, sub, difference, darken, lighten),
color/luminosity blending for RGB and CMYK
- RAW support (via dcraw), up to 5 color samplers, histograms and color
matrices, etc.
FT is a generic, native graph management system for GNUstep and Cocoa and
is written in Objective-C. With FT you can persistently manage graphs
consisting of nodes and edges. Each node may provide so-called services.
Such a service may be e.g. a dictionary services, which all nodes provide
at present. This service allows the storage of any data in a node and is
based on keys which uniquely identify content within a dictionary.

The GIMP is designed to provide an intuitive graphical interface to a
variety of image editing operations. Here is a list of the GIMP's
major features:
Image editing
-------------
* Selection tools including rectangle, ellipse, free, fuzzy, bezier
and intelligent.
* Transformation tools including rotate, scale, shear and flip.
* Painting tools including bucket, brush, airbrush, clone, convolve,
blend and text.
* Effects filters (such as blur, edge detect).
* Channel & color operations (such as add, composite, decompose).
* Plug-ins which allow for the easy addition of new file formats and
new effect filters.
* Multiple undo/redo.
A simple viewer for edj files. Should provide more ease of use than the edje
viewer that comes with edje itself.
A screen saver module which bounces a line around the screen.
I originally submitted this as a kernel module, but after
seeing George Reid's plasma-kmod port I realised that was
a better way to do it.
Little CMS intends to be a small-footprint color management library, with
special focus on accuracy and performance. It uses the International Color
Consortium standard (ICC), and offers fast transformation routines between
ICC profiles.
Color management refers to techniques that ensure consistent colors while
images are transferred from scanners or cameras to monitors and printers.
