PDF::API2 is 'The Next Generation' of Text::PDF::API, a Perl module-chain that facilitates the creation and modification of PDF files. It features support for the 14 base PDF Core Fonts, TrueType fonts, and Adobe-Type1, with unicode mappings, embedding of bitmap images, compression via zlib, and a rich object-oriented API.
The Paranoid modules provide a number of routines that are intended for use in strict and taint-safe scripts. The modules cover a variety of tasks from command-line argument parsing to process and network management. All of the modules use a debug trace framework for diagnostic output that is easily used and extended for application code as well.
Report Magic is an add-on for Analog, a Web site logfile analysis program. Generated reports include a description with tabulated, graphed, and summarized results. All colors, fonts, and background images are completely customizable to help make resulting reports fit the theme of your Web site. Report Magic has translations for several languages. It runs on any platform that will run Perl and pre-compiled versions are available for Win32 and Mac.
Sman is "The Searcher for Man Pages", an enhanced version of "apropos" and "man -k". Sman adds several key abilities over its predecessors, including stemming and support for complex boolean text searches such as "(linux and kernel) or (mach and microkernel)". It shows results in a ranked order, optionally with a summary of the manpage with the searched text highlighted. Searches may be applied to the manpage section, title, body, or filename. The complete contents of the man page are indexed. A prebuilt index is used to perform fast searches.
The metric implemented in the Image::Density Perl Module estimates the density of data where there is data, and has a reasonable correlation with goodness as judged by humans. That is, if you let a human look at a set of images and judge quality, the density values for those images as calculated here tend to correlate well with the human judgement (densities that are too high or too low represent "bad'' images). It is intended for use on bitonal TIFF images, such as those from scanning paper documents.
