PDF Automation Server (PAS) can receive PDF documents from multiple sources concurrently, including email, FTP servers, and local or network folders. Processes can then be defined independently for each document source to perform a number of different functions on the documents. Finally, PAS can route the original or modified document to multiple destinations, including folders, printers, email, and FTP servers. PAS supports the following PDF processing functions: printing, setting security, conversion to images, merging, flattening, and extraction of form field data, importing, exporting, and flattening of annotations, text extraction, assembling, splitting, merging, digital signatures, and stamping.
The Big Faceless Java PDF Viewer is a Swing component that can display PDF documents. It is intended for developers who don't require the full API. The PDF Viewer can be installed as an applet, an application, via Java Web Start, or embedded in a Swing application. Printing, saving, text search, forms, digital signatures, and annotations are some of the many features available. The viewer can be tailored to include just the features you need, and is a cost-effective solution for those needing the features of Adobe Acrobat on a Java platform.
Pod::Manual is a module that gathers the pod of several Perl modules into a comprehensive manual. Its primary objective is to generate a document that can be printed, but it also allow to output the document into other formats (e.g., docbook). podmanual is a utility that uses Pod::Manual.
PTRANS reads P5 and P6 (PGM, PPM, PNM) files, and performs Floyd-Steinberg dithering and scaling while only holding two scanlines of image data at a time. It can be used on gigapixel images while only consuming a small amount of RAM. It outputs P4 (PBM) dithered monochrome bitmap and P5 (PGM) grayscale images. It performs pixel interpolation and smoothing. Gamma correction and contrast curves may be set from the command line.
Moonshiner is a graphical frontend for Ghostscript's PostScript-to-PDF converter. While Ghostscript (and its wrapper ps2pdf) is a very powerful instrument, it is quite challenging to use its parameters on the command line, especially if you often change the settings as to what kind of color conversion, image resampling, etc. you want Ghostscript to perform. While the author has never used Adobe's Distiller, and thus cannot really compare the two, Moonshiner (as the name suggests) is supposed to be a work-alike for the Linux world (at least GUI-wise, as the actual work is of course done by Ghostscript).
Post Scriptum is a programming language for preparing PostScript documents and programs. The language is procedural, and uses classical control structures (functions, loops, and conditional statements) and commonly known data types (numbers, arrays, strings, and dictionaries). Its syntax is simple, clear, and easy to learn. The compiler translates programs written in Post Scriptum directly to a PostScript file, which can be than executed by a PostScript interpreter (such as Ghostscript), printed, or used as a procset, driver, or library.
