Fracplanet is an application to generate random planets and terrain
with oceans, mountains, icecaps and rivers. Parameters are specified
interactively and the results displayed using OpenGL. The generated
objects can be dumped in Pov-Ray format.
The GdkPixBuf library provides a number of features:
- Image loading facilities.
- Rendering of a GdkPixBuf into various formats:
drawables (windows, pixmaps), GdkRGB buffers.
- A cache interface

This is a library for OpenGL to load PNG graphics files as an
OpenGL texture as easily as possible. It also has a number of
options for generating the alpha channel and mipmaps.
epstool - Create or extract preview bitmaps in EPS files.
Features:
- Add EPSI or DOS EPS previews.
- Extract postscript from DOS EPS files.
- Uses Ghostscript to create preview bitmaps.
- Scan a bitmap created by Ghostscript to find bounding box.
- Create TIFF or Interchange from part of a bitmap created
by Ghostscript.
HDR Tools is a set of command-line tools for creating and manipulating High
Dynamic Range (HDR) images. It consists of six programs: hdr_create,
hdr_fix_ca, hdr_denoise, hdr_squish, hdr_adjust, and hdr_convert.
Together, they can convert a set of bracketed photographs to HDR image (in
EXR format), fix chromatic aberrations and CCD noise, perform tone mapping
and some simple color manipulations, apply gamma correction and optionally
adjust the exposure, crop, and finally convert the result into a "normal"
image (a JPG, for example).
icon-slicer is a utility for generating icon themes and libXcursor cursor
themes.
The inputs to icon-slicer are conceptually:
A) a set of multi-layer images, one for each size
B) a XML theme description file
Each image contains all the cursors arranged in a grid; for cursors the
layers are:
- a layer with a dot for the hotspot of each cursor
- the main image or first animation frame for multi-frame animated cursors
- the second animation frame for multi-frame animated cursors
For icons, the layers are:
- a layer with the images
- an optional layer with attachment points for emblems
- an optional layer with boxes for embedding text into icons
In practice, since loading of multilayer images is not supported by standard
image libraries, each layer is input as a separate image file.
ImageViewer is a small application which display images based on the
GNUstep API. In the future I will add image catalogue creation and
other goodies, right now it is what it is, an image viewer application.

This is the Image Compiler, which generates images from textual description.
Most important features include:
- Does not need display to run
- Can be run from the command line or as CGI script. In the latter case,
the image is output to the browser (in PNG or JPEG format)
- The size of the output image is automatically determined, no size has to
be specified (although you can give a fixed size
- Coordinates are in pixels, only positive coordinates are visible. Angles
are in integer degrees, no limitations (except the maximum integer limit).
Colors can be specified in one of three formats, including X11 color
(rgb) strings
- A pre-processor can be applied on the input file first; simple
arithmetic can be performed
- Supports commands for drawing lines, circles (filled or not), rectangles
(filled or not), ellipses (filled or not), arcs, and text. Images can
also be imported. For text and images an alignment parameter is
available, and text and images can be rotated over any angle and can
also be mirrored
jbig2dec is a decoder implementation of the JBIG2 image compression format.
JBIG2 is designed for lossy or lossless encoding of 'bilevel' (1-bit monochrome)
images at moderately high resolution, and in particular scanned paper documents.
In this domain it is very efficient, offering compression ratios on the order of
100:1.
