"jpgtn" is based on "tnpic" by Russell Marks and on "gtnpic" by Willie
Daniel. "tnpic" was originally distributed as a utility with Marks' "zgv"
program. "gtnpic" was an attempt to clean up and expand upon the original
tnpic program and "maybe add some new features along the way." Jpgtn
differs from both "tnpic" and "gtnpic" in purpose. It is *not* an indexer
of image files. It simply creates thumbnails of images stored in JPEG
format.
AMIDE is a competely free tool for viewing, analyzing, and registering
volumetric medical imaging data sets. It's been written on top of GTK+, and runs
on any system that supports this toolkit.
Art of Illusion is a free, open source 3D modelling and rendering studio.
Many of its capabilities rival those found in commercial programs.
Highlights include subdivision surface based modelling tools,
skeleton based animation, and a graphical language for designing procedural
textures and materials..
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.
The goal of the lensfun library is to provide an open source database of
photographic lenses and their characteristics. In the past there was an
effort in this direction (see http://www.epaperpress.com/ptlens/), but then
author decided to take the commercial route and the database froze at the
last public stage. This database was used as the basement on which lensfun
database grew, thanks to PTLens author which gave his permission for this,
while the code was totally rewritten from scratch (and the database was
converted to a totally new, XML-based format).
The lensfun library not only provides a way to read the lens database and
search for specific things in it, but also offers a set of algorithms for
correcting images based on detailed knowledge of lens properties and
calibration data. Right now lensfun is designed to correct distortion,
transversal (also known as lateral) chromatic aberrations, vignetting, and
colour contribution of the lens (e.g. when sometimes people says one lens
gives "yellowish" images and another, say, "bluish").
libEMF is a C/C++ library which provides a drawing toolkit
based on ECMA-234. The general purpose of this library is
to create vector graphics files on POSIX systems which can
be imported into StarOffice/OpenOffice.
GLText is a portable font rendering library for C++ OpenGL applications. It
uses FreeType2 to read and render high-quality TrueType fonts with a minimal
footprint. With just a few easy lines of C++, you can add gorgeously
rendered text to your graphical applications.
GLText is an open source project licensed under the LGPL. Basically this means
that you can use and link your application with it regardless of what license
your application uses. If you make changes to GLText, however,
you must make those changes open source under the LGPL.
Written with portablility in mind, GLText works on Windows, Linux, FreeBSD and
IRIX - virtually anywhere that FreeType2 supports.
libgnomecanvasmm provides C++ wrappers for libgnomecanvas, for use with gtkmm.
A GUI for Panorama Tools, to stitch panoramic images.
With hugin you can assemble a mosaic of photographs into a complete
immersive panorama, stitch any series of overlapping pictures and much
more.
libiptcdata is a library, written in C, for manipulating the International
Press Telecommunications Council (IPTC) metadata stored within multimedia files
such as images. This metadata can include captions and keywords, often used by
popular photo management applications. The library provides routines for
parsing, viewing, modifying, and saving this metadata. The libiptcdata
package also includes a command-line utility, iptc, for editing IPTC data in
JPEG files.
