Deegree's WPS is able to process Feature Collections based on arbitrary processes. OGC's WPS (Schut & Whiteside 2005) specification describes WPS as follows: "WPS defines a standardized interface that facilitates the publishing of geospatial processes, and the discovery of and binding to those processes by clients. "Processes" include any algorithm, calculation or model that operates on spatially referenced data. "Publishing" means making available machine-readable binding information as well as human-readable metadata that allows service discovery and use."

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.

Pixie is a RenderMan like photorealistic renderer. It is being developed in the hope that it will be useful for graphics research and for people who can not afford a commercial renderer. Some of supported features: * All RenderMan 3.4 primitives * Programmable shading (RenderMan Shading Language) * High quality texture/shadow/environment mapping * High dynamic range input/output * Raytracing * Motion blur * Depth of field * Reyes style rendering (very fast) * Occlusion culling * Area light sources * Network parallel rendering * DSO shaders * Global illumination * Photon mapping

Entangle is an application which uses GTK+3 and libgphoto2 to provide a graphical interface for tethered photography with digital cameras. It includes control over camera shooting and configuration settings and "hands off" shooting directly from the controlling computer: - Trigger the shutter from the computer - Live preview of scene before shooting - Automatic download and display of photos as they are shot - Control of all camera settings from computer

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.

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.
