PostScript lacks a lot of basic operators such as tan, acos, asin, cosh, sinh, tanh, acosh, asinh, atanh, exp (with e base). Also (oddly) cos and sin use arguments in degrees. Pst-math provides all those operators in a header file pst-math.pro with wrappers pst-math.sty and pst-math.tex. In addition, sinc, gauss, gammaln and bessel are implemented (only partially for the latter). The package is designed essentially to work with pst-plot but can be used in whatever PS code (such as pstricks SpecialCoor "!", which is useful for placing labels). The package also provides a routine SIMPSON for numerical integration and a solver of linear equation systems.
The package enables the user to connect information, and to place labels, without knowing (in advance) the actual positions of the items to be connected, or where the connecting line should go. The macros are useful for making graphs and trees, mathematical diagrams, linguistic syntax diagrams, and so on. The package contents were previously distributed as a part of the pstricks base distribution; the package serves as an extension to PSTricks.
The package is useful when building an image from assorted material, as in the slides of a projected presentation. The package requires pstricks, and shares that package's restrictions on usage when generating PDF output.
The package provides plotting of data (typically from external files), using PSTricks. Plots may be configured using a wide variety of parameters.
Pst-text is a PSTricks based package for plotting text along a different path and manipulating characters. It includes the functionality of the old package pst-char.
The package provides helper functions for other PSTricks related packages.
Collects together examples that have been posted to the pstricks mailing list, together with many additional features for the basic pstricks, pst-plot and pst-node, including: bugfixes; new options for the pspicture environment; arrows; braces as node connection/linestyle; extended axes for plots (e.g., logarithm axes); polar plots; plotting tangent lines of curves or functions; solving and printing differential equations; box plots; matrix plots; and pie charts. The package makes use of PostScript routines provided by pst-math.
Pxfonts supplies virtual text roman fonts using Adobe Palatino (or URWPalladioL) with some modified and additional text symbols in the OT1, T1, and TS1 encodings; maths alphabets using Palatino/Palladio; maths fonts providing all the symbols of the Computer Modern and AMS fonts, including all the Greek capital letters from CMR; and additional maths fonts of various other symbols. The set is complemented by a sans-serif set of text fonts, based on Helvetica/NimbusSanL, and a monospace set derived from the parallel TX font set. All the fonts are in Type 1 format (AFM and PFB files), and are supported by TeX metrics (VF and TFM files) and macros for use with LaTeX.
The package defines new commands \Centering, \RaggedLeft, and \RaggedRight and new environments Center, FlushLeft, and FlushRight, which set ragged text and are easily configurable to allow hyphenation (the corresponding commands in LaTeX, all of whose names are lower-case, prevent hyphenation altogether).
This small package replaces \textsuperscript and \textsubscript commands by equivalent commands that use OpenType font features to access appropriate glyphs if possible. The package also patches LaTeX's default footnote command to use this new \textsuperscript for footnote symbols. The package requires fontspec running on either XeLaTeX or LuaLaTeX. The package holds functions that were once parts of the xltxtra package, which now loads realscripts by default.
