Scan Tailor is an interactive post-processing tool for scanned pages.
It performs operations such as page splitting, deskewing, and removing
garbage. All operations can be done automatically, however it's still
possible to manually correct their results
Quantum GIS (QGIS) is a user friendly Open Source Geographic Information
System. QGIS supports vector, raster, and database formats.
QGIS is licensed under the GNU GPL.
Some of the major features include:
- Support for spatially enabled PostGIS tables
- Support for shapefiles, ArcInfo coverages, Mapinfo and other formats
- Raster support for a large number of formats
- Identify features
- Display attribute tables
- Select features
- GRASS Digitizing
- Feature labeling
Tiled is a general purpose tile map editor. It's built to be easy
to use, yet flexible enough to work with varying game engines,
whether your game is an RPG, platformer or Breakout clone. Tiled
is free software and written in C++, using the Qt application
framework. The main features in a nutshell:
* General purpose tile map editor with XML-based map format
* Supports orthogonal and isometric maps
* Custom objects can be placed with pixel precision
* Full undo/redo and copy/paste support
* Add custom properties to tiles, layers, objects or the map
* Automatically reloads tilesets when changed externally
* Resize or offset your tile map later as needed
* Efficient tile editing tools like stamp and fill brushes
* Supports input/output plugins to open and save files in custom
formats
C++ library to create, manipulate, and render SVG files
This library servers for displaying PNG images in programs
using the Allegro multimedia library.
Xournal is an application for notetaking, sketching, keeping a journal using a
stylus. It is similar to Microsoft Windows Journal or to other alternatives such
as Jarnal, Gournal, and NoteLab.
Xournal aims to provide superior graphical quality (subpixel resolution) and
overall functionality; however it lacks the collaborative features of Jarnal.
Since Xournal is still in its early development stages, it may not be fully
stable, and some features have not been implemented yet.
Xournal supports annotation of PDF files through the Poppler library; PDF files,
much like paper styles, are loaded as an immutable background image.
Luminance HDR is an open source graphical user interface application that
aims to provide a complete workflow for HDR image processing.
Supported features:
* Create an HDR file from a set of images (formats: JPEG, TIFF 8-bit and
16-bit, RAW) of the same scene taken at different exposure settings
* Rotate, resize, and crop HDR images
* Tonemap HDR images
* Copy EXIF data between sets of images
Supported HDR formats (with file extensions):
* OpenEXR (.exr)
* Radiance RGBE (.hdr)
* TIFF formats: 16-bit, 32-bit (float) and LogLuv (.tiff)
* PFS native format (.pfs)
* Raw image formats (various)
Supported LDR formats: JPEG, PNG, PPM, PBM, TIFF (8-bit).

LuxRender is a physically based and unbiased rendering engine. Based on
state of the art algorithms, LuxRender simulates the flow of light according
to physical equations, thus producing realistic images of photographic
quality. Some of the main features of LuxRender are:
* biased and unbiased rendering: Users can choose between physical
accuracy (unbiased) and speed (biased);
* full spectral rendering: Instead of the RGB colour spectrum, full
spectra are used for internal calculations;
* hierarchical procedural and image based texture system: Procedural and
image based textures can be mixed in various ways, making it possible to
create complex materials;
* displacement mapping and subdivision: Based on procedural or image
textures, object surfaces can be transformed;
* network and co-operative rendering: Rendering time can be reduced by
combining the processing power of multiple computers;
* perspective (including shift lens), orthographic, and environment
cameras;
* HDR output: Render output can be saved in various file formats,
including .png, .tga, and .exr.
Fully functional exporters are available for Blender and Maya, while
exporters for a growing number of 3D applications are under development.
Mandelbulber is an experimental application that helps to make
rendering 3D Mandelbrot fractals much more accessible. A few of the
supported 3D fractals: Mandelbulb, Mandelbox, BulbBox, JuliaBulb,
Menger Sponge, Quaternion, Trigonometric, Hypercomplex, and Iterated
Function Systems (IFS). All of these can be combined into infinite
variations with the ability to hybridize different formulas together.
