PicBook automatically produces a photo album in HTML format of your scanned images or photographs. It come with automatic image processing, slideshow, transition effects, and other nifty features. It is easy to customise with its configuration file and HTML-templates. PicBook is a Bourne shell script and therefore should run on any Unix or Linux system. It requires the standard grep and awk commands, which should be available on most systems. Additionally, it needs the "convert" and "identify" commands from the ImageMagick package to handle images.
PikView is an image viewer which uses the KDE libraries. It can read the following image types: PNG, JPEG, TIFF, GIF, NetPBM, and, via the (optional) ImageMagick library, PSD, TGA, EPS, PICT, DCX, PCX, MIF, BMP, VIFF, and PNM. It also supports asynchronous preloading, zooming, thumbnails (cachable), rapid image filing, fullscreen, printing, slideshow, flicker-free repainting, drag-and-drop moving/copying, and Konqueror embedding.
Pixelize is a program that will use many scaled-down images to try to duplicate, as closely as possible, another image. It works by splitting up the image you want rendered (or duplicated) into a grid of small rectangular areas. Each area is analyzed and replaced with an image chosen from a large database of images. Pixelize tries to pick images that best match each area.
PLIB is a set of libraries to write games and other realtime interactive applications that are 100% portable across a wide range of hardware and operating systems. It's used by Majik3D, FlightGear, and others, and includes libraries for GUI widgets, sound replay, geometry, scene graph, joystick, and fonts/text.
PLOTICUS is a command line utility for creating bar, line, pie, boxplot, scatterplot, sweep, heatmap, vector, timeline, Venn diagrams, and other types of charts and plots. ploticus is good for automated or just-in-time graph generation. It handles date, time, and categorical data nicely, and has some basic statistical capabilities. It can output to GIF, PNG, SVG, SWF, JPEG, PostScript, EPS, and X11. You can use convenient preset options or create complex scripts with rich and detailed color and style operations.
Pmw is a toolkit for building high-level compound widgets in Python using the Tkinter module. It consists of a set of base classes and a library of flexible and extensible megawidgets built on this foundation. These megawidgets include notebooks, comboboxes, selection widgets, paned widgets, scrolled widgets and dialog windows.
pngcheck is the official PNG tester and debugger. Originally designed simply to test the CRCs within a PNG image file (e.g., to check for ASCII rather than binary transfer), it has since been extended to check and optionally print almost all the information about a PNG image and to verify that it conforms to the PNG specification. It also includes partial support for MNG animations.
