For an overview of Ghostscript and a list of the documentation files, see README. Generally used 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_btokn.ps - gs_init.ps reads this in if the btoken feature is included in the configuration. It provides support for binary tokens. gs_ccfnt.ps - gs_init.ps reads this in if the ccfonts feature is included in the configuration. It provides support for compiled fonts. 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 PostScript files that really want to be printed on a LaserWriter. 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. gs_lev2.ps - gs_init.ps reads this in if the Ghostscript interpreter includes Level 2 PostScript functions. It contains definitions of procedures and miscellaneous initialization for the Level 2 functions. gs_res.ps - gs_init.ps reads this in if the Level 2 resource machinery is included. Currently, this is the case for all Level 2 configurations. gs_type1.ps - gs_init.ps reads this in if the Ghostscript interpreter includes Type 1 font capability (which it normally does). gs_*_e.ps - These files define the Encodings known to Ghostscript. All of them except gs_std_e.ps and gs_iso_e.ps are loaded only if referenced. More obscure system files ------------------------- gs_cmdl.ps - This file is not used yet. Eventually it will replace C code that parses the Ghostscript command line. gs_diskf.ps - This file implements the -dDISKFONTS feature (diskfont.dev). See use.txt for a description of this feature. gs_kanji.ps - This file provides support for the Wadalab free Kanji font. It is not included automatically in any configuration. gs_pdfwr.ps - This file contains some patches for providing information to the pdfwrite driver. It is included only if the pdfwrite driver is included. gs_pfile.ps - This file provides runtime support for packed fonts. It is not included automatically in any configuration. PDF-specific system files ------------------------- gs_pdf.ps - The ProcSet that provides runtime support for PDF files. pdf2ps copies this into its output. gs_l2img.ps - The ProcSet that emulates the PostScript Level 2 'image' operator on Level 1 systems. pdf2ps copies this into its output if the PSLevel1 option was selected. pdf_2ps.ps - The additions to the PDF interpreter that allow it to convert PDF to PostScript. pdf_base.ps - Utilities for interpreting PDF objects and streams. pdf_draw.ps - The interpreter for drawing-related PDF operations. pdf_font.ps - Code for handling fonts in PDF files. pdf_main.ps - Document- and page-level control for interpreting PDF files. 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. ridt.eps - The RIDT '91 logo. Note that since this is an EPS file, you will have to add -c showpage at the end of the command line to print it or convert it to a raster file. Utilities --------- For more information on these utility programs, see the comments at the beginning of the files. The ones marked with * have batch files or shell scripts of the same name (e.g., bdftops, bdftops.bat) to invoke them conveniently. align.ps - a test page for determining the proper margin and offset parameters for your printer. bench.ps - a file useful for running benchmarks. * bdftops.ps - a utility for converting BDF fonts to outline form: see fonts.txt for more information. caption.ps - a file for putting a caption in a box at the bottom of each page, useful for trade show demos. docie.ps - an emulation of the CIE color mapping algorithms. * 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. level1.ps - a file that turns off any Level 2 features. packfile.ps - a utility for compressing fonts into a single file. prfont.ps - a utility to print a font catalog. * ps2ascii.ps - a utility for extracting the ASCII text from PostScript source files. It redefines many operators. For more information, see the comments in the file. ps2ai.ps - a utility for converting an arbitrary PostScript file into a form compatible with Adobe Illustrator. NOTE: ps2ai doesn't work properly with Adobe's Helvetica-Oblique font, and other fonts whose original FontMatrix involves skewing or rotation. * ps2epsi.ps - a utility for converting an arbitrary PostScript file into EPSI form. quit.ps - a file containing just the word "quit". (The -c switch now makes this unnecessary; this file exists for backward compatibility.) rollconv.ps - a utility for converting files produced by Macromedia's Rollup program to a Type 0 form directly usable by Ghostscript. showpage.ps - a file containing just the word "showpage". (The -c switch now makes this unnecessary; this file exists for backward compatibility.) viewcmyk.ps - a utility for displaying CMYK files. viewgif.ps - a utility for displaying GIF files. viewjpeg.ps - a utility for displaying JPEG files. viewpcx.ps - a utility for displaying PCX files. viewpbm.ps - a utility for displaying PBM/PGM/PPM files. waterfal.ps - a utility to print a "waterfall" of fonts at different sizes. Development tools ----------------- acctest.ps - a utility that checks whether the interpreter enforces access restrictions. decrypt.ps - a utility for decrypting the eexec section of a font. markpath.ps - a utility for showing the points on a path. pcharstr.ps - a utility for printing out the CharStrings and Subrs in a Type 1 font. ppath.ps - a couple of utilities for printing out the current path, for debugging. traceop.ps - a utility for tracing uses of any procedure or operator for debugging. type1enc.ps - the Type 1 font format encryption and decryption algorithms, written in PostScript. uninfo.ps - some utilities for printing out PostScript data structures. unprot.ps - a prologue to disable access checking. viewps2a.ps - a utility for displaying the output of ps2ascii.ps. winmaps.ps - a utility for creating mappings between the Adobe encodings and the Microsoft Windows character sets. wrfont.ps - a utility for writing out an unprotected Type 1 font, such as the standard Ghostscript fonts. zeroline.ps - a utility for testing how interpreters handle zero-width lines. Odds and ends ------------- lines.ps - a test program for line joins and caps. type1ops.ps - the Type 1 font format opcodes.
