Multican is Canon EOS cameras USB remote control utility for 300D, 350D, 30D,
20D, and 5D. Multican allows scripted remote control of multiple cameras; it
is possible to control up to six cameras attached at the same time.
Multican communicates with camera directly, without generic library such as
provided by gPhoto2, and currently has no GUI, which makes it no replacement
for Canon's EOS Utility, but it can be useful nonetheless in various setups,
e.g. for astrophotography.
mtPaint is a simple GTK+1/2 painting program designed for creating icons
and pixel based artwork. It can edit indexed palette or 24 bit RGB images
and offers basic painting and palette manipulation tools. It also has
several other more powerful features such as channels, layers and
animation. Due to its simplicity and lack of dependencies it runs well on
GNU/Linux, Windows and older PC hardware.
Non-Uniform Rational B-Splines (NURBS) are parametric functions which can
represent any type of curves or surfaces. This C++ library hides the basic
mathematics of NURBS, allowing the user to focus on the more challenging
parts of their projects.
The NURBS++ package includes a matrix library, an image manipulation
library, a numerical library and a NURBS library.
This library is copyrighted under the terms of the LGPL by its author,
Phillipe Lavoie <lavoie@zeus.genie.uottawa.ca>.
OpenRM Scene Graph is set of tools and utilities that implement a
high performance, flexible and extendible scene graph API. Underneath
OpenRM, OpenGL(tm) is used as the graphics platform for rendering,
so OpenRM is highly portable and can deliver blazing rendering speeds.
OpenRM can be used on any platform that has OpenGL, and has been
built and tested on:
x86 Linux (s/w via Mesa, h/w using vendor drivers, e.g., nVidia)
Irix
Solaris
FreeBSD
Win32 (95/98/NT/2K/ME).
OpenRM is a derivative work of RM Scene Graph (tm), a commercial
scene graph product from R3vis Corporation. Late in 1999, R3vis announced
the release of OpenRM into the Open Source community, with the
OpenRM debut occuring on 1 March 2000. R3vis continues to maintain
and develop RM Scene Graph, which contains additional features not
present in OpenRM.
OptiPNG is a PNG optimizer that recompresses image files to a smaller
size, without losing any information. This program also converts
external formats (BMP, GIF, PNM; TIFF support is coming up) to optimized
PNG, and performs PNG integrity checks and corrections.
The idea has been inspired from pngcrush, and is explained in detail in
the PNG-Tech article "A guide to PNG optimization". The implementation
is carried forward in OptiPNG, which offers a faster execution per
trial, and a wider search space.
Panorama viewer using OpenGL
A set of command line (and one GUI) programs for reading, writing, manipulating
and viewing high-dynamic range (HDR) images and video frames.
PIDDLE - Plug-In Drawing, Does Little Else
------------------------------------------
PIDDLE is a Python module for creating two-dimensional graphics in a
manner that is both cross-platform and cross-media; that is, it can
support screen graphics (e.g. QuickDraw, Windows, Tk) as well as file
output (PostScript, PDF, GIF, etc.). It makes use of the native 2D
drawing calls of each backend, for maximum efficiency and quality. It
works by defining a base class (piddle.Canvas) with methods for all
supported drawing primitives. A particular drawing context is provided
in the form of a derived class. PIDDLE applications will be able to
automatically select an appropriate backend for the user's environment.
Pngnq is a tool for quantizing PNG images in RGBA format.
Pngnq is an adaptation by Stuart Coyle of Greg Roelf's pnqquant using
Anthony Dekker's neuquant algorithm.
The neuquant algorithm uses a neural network to optimise the color map
selection. This is fast and quite accurate, giving good results on many
types of images.
The PNGwriter library, which requires libpng, allows you to plot to a 48-bit
PNG file, saving it directly to disk. Plotting is as easy as specifying the
red, green, and blue values and the x, y coordinates of the pixel. It includes
functions for plotting simple geometric shapes (circle, rect, line), reading
the colour of a pixel, reading in a whole PNG file (great for image analysis),
plotting and reading in HSV colourspace, and many others that might come in
handy.
