Mapnik is a toolkit for developing GIS applications. At the core is a C++ shared library providing algorithms/patterns for spatial data access and visualization. Essentially a collection of geographic objects (map, layer, datasource, feature, and geometry), the library doesn't rely on "windowing systems" and can be deployed in any server environment. It is intended to play fair in a multi-threaded environment and is aimed primarily, but not exclusively, at Web-based development. High-level Python bindings (boost.python) facilitate rapid application development, targeting zope3, django, etc.
PDF 2 PSP is a simple tool for converting PDF documents and printouts into JPEG images suitable for displaying on the Sony PSP handheld game console. This allows you to download e-books, game manuals, album liners, etcetera to your PSP. Once they're on your PSP, you can read them anywhere. Because of the extensive PDF support built into OS X, any document you can print can be stored as a PDF and converted and downloaded to your PSP. It works best when used with a PSP synchronization tool such as PSPWare, but it can also be used as a stand-alone tool.
JLM image viewer is able to view standard image types as well as JLM and PLM image types. It is also able to lighten or darken an image using a "lightspace" technique. The technique is equivalent to changing the exposure time of the camera which took the image. The lightening or darkening method is generally considered superior to techniques found (such as gamma correction) which are found in image manipulation programs such as photoshop or the GIMP.
