For an overview of Ghostscript and a list of the documentation files, see README. System files ------------ gs_init.ps - Ghostscript reads this automatically when it starts up. It contains definitions of many standard procedures and initialization for a wide variety of things. gs_fonts.ps - gs_init.ps reads this in. It initializes Ghostscript's font machinery and provides some utility procedures that work with fonts. gs_statd.ps - gs_init.ps reads this in. It creates a dummy statusdict and some other environmental odds and ends for the benefit of P*stScr*pt files that really want to be printed on a LaserWriter. gs_2asc.ps - This utility file helps extract the ASCII text from PostScript source files. It redefines many operators. For more information, see the comments in the file. gs_dps1.ps - gs_init.ps reads this in if the dps feature is included in the configuration. It provides support for various Display PostScript and Level 2 features. sym__enc.ps - the Symbol encoding, loaded only if referenced. Art --- chess.ps - A black-and-white chessboard. golfer.ps - A gray-scale picture of a stylishly dressed woman swinging a golf club. escher.ps - A colored version of a hexagonally symmetric Escher drawing of interlocking butterflies. Can be printed on monochrome devices, with somewhat less dramatic results. cheq.ps - A chessboard "font" used by chess.ps (obtained from the Adobe file server). snowflak.ps - A rectangular grid of intricate colored snowflakes. (Renders very slowly.) colorcir.ps - A set of nested ellipses made up of colored bars. tiger.ps - A dramatic colored picture of a tiger's head. Utilities --------- For more information on these utility programs, see the comments at the beginning of the files. bdftops.ps - a utility for converting BDF fonts to outline form: see fonts.doc for more information. decrypt.ps - a utility for decrypting the eexec section of a font. gslp.ps - a utility for doing "line printing" of plain text files. impath.ps - a utility for reconstructing outlines from bitmap images, used by bdftops. landscap.ps - a file that you can put in front of your own files to get them rendered in landscape mode. pstoppm.ps - a utility for rendering PostScript files onto PPM (bitmap) files. ps2image.ps - a utility for converting an arbitrary PostScript file into a .ps file consisting of just PostScript bitmaps, one per page. wrfont.ps - a utility for writing out an unprotected Type 1 font, such as the standard Ghostscript fonts. Odds and ends ------------- empty.ps - an empty file. lines.ps - a test program for line joins and caps. pcharstr.ps - a program to print out the CharStrings and Subrs in a Type 1 font. ppath.ps - a couple of utilities for printing out the current path, for debugging. prfont.ps - a program to print a font catalog. quit.ps - a file containing just the word "quit". traceop.ps - a memory usage monitor for debugging. type1ops.ps - the Type 1 font format opcodes. unprot.ps - a program to disable access checking.
