PoDoFo is a library to work with the PDF file format. The name comes
from the first letter of PDF (Portable Document Format). A few tools
to work with PDF files are already included in the PoDoFo package.
Impressive is a program that displays PDF presentation slides with style.
Smooth alpha-blended slide transitions are provided for the sake of eye
candy, but in addition to this, Impressive offers some unique tools that
are very useful for presentations.
JpGraph is an OO class library for PHP. JpGraph makes it easy to
draw both "quick and dirty" graphs with a minimum of code and complex
professional looking graphs which requires a very fine grain of control.
The library assigns context sensitive default values for most parameters
which helps minimize the learning curve.
potrace is a Peter Selinger's GPLed utility for tracing
bitmaps - converting them into smooth, scalable images.
It accepts as input a bitmap B/W images (PBM, PGM, PPM
and BMP formats), and returns encapsulated PostScript
(EPS) as the default output. Other output format are
available: PS, SVG, Xfig, PGM, PDF and experimental
GimpPath.
You can create scalable images from scans, such as
logos, hand taken notes, etc. The resulting smooth
images can then be rendered at any resolution.
Precision Raster Image Convolution Engine.
PRICE can open several image file formats and apply high-quality filters
and other enhancements.
projectM is an LGPL'ed reimplementation of Milkdrop under OpenGL. All projectM
requires is a video card with 3D acceleration and your favorite music.
pstoedit converts Postscript(TM) and PDF files to other vector graphic
formats so that they can be edited graphically.
This set of C (Cython) extensions provides acceleration of common
operations for slow points in PyOpenGL 3.x.
PyOpenGL is an interface between the Python programming language and the OpenGL
library (and related libraries). The package provides interfaces to:
- The OpenGL library itself, which is a three-dimensional graphical
rendering interface. For more information, visit
http://www.opengl.org.
- The GLU library which provides access to routines for doing
quadrics, tesselation etc.
- The GLUT (GL UTilitity) library from Mark Kilgard, which provides a
windowing environment.
- The Togl (Tk/OpenGL) widget from Brian Paul and Ben Benderson (an
alternative to GLUT which interfaces to Tk).
The Python bindings offer some value-added tools in addition to the
standard API, including support for fast processing of arrays of
coordinates, trackball support, etc.
PyX is a Python package for the creation of encapsulated PostScript figures.
It provides both an abstraction of PostScript and a TeX/LaTeX interface.
Complex tasks like 2d and 3d plots in publication-ready quality are built out
of these primitives.
Features
* PostScript output for device independent, free scalable figures
* seamless TeX/LaTeX integration
* full access to PostScript features like paths, linestyles, fill patterns,
transformations, clipping, etc.
* advanced geometric operations on paths like intersections, transformations,
splitting, etc.
* sophisticated graph generation: modular design, pluggable axes, axes
partitioning based on rational number arithmetics, flexible graph styles,
etc.
