Ghostscript has a notion of 'output devices' which handle saving or displaying the results in a particular format. "display device" window will still appear). And the "c" suffix indicates a Windows console based binary (note that the Gswin32.exe is for x86 Windows systems, whilst gswin64.exe is for x86_64 Windows On Windows, the two digit number indicates the word length of the system for which the binary was built (so On other systems the executable may have a different name: System The message shows for that version of the Ghostscript executable: You can get a brief help message by invoking Ghostscript with the Please see the reference sections on options and devices for a more complete listing. The most important are described in detail here. Many of them include " ="įollowed by a parameter. An option may appear anywhere in the command line, and applies to all files named after it on the line. The interpreter also quits gracefully if it encounters end-of-file or control-C. The -dBATCH -dNOPAUSE options in the examples above disable the interactive prompting. After processing the files given on the command line (if any) it reads further lines of PostScript language commands from the primary input stream, normally the keyboard, interpreting each line separately. The interpreter runs in interactive mode by default. The interpreter reads and executes the files in sequence, using the method described under " File searching" to find them. (EPS), DOS EPS (EPSF), and Adobe Portable Document Format (PDF). Ghostscript is capable of interpreting PostScript, encapsulated PostScript You can use the 'ps2' set with eps files. These just call Ghostscript with the appropriate There are other utility scripts besides ps2pdf, including pdf2ps, ps2epsi, pdf2dsc, ps2ascii, There are also a number of utility scripts for common to convert a PostScript document to PDF: ps2pdf file.ps dTextAlphaBits=4 -sOutputFile='paper-d.pgm' paper.ps To rasterize a whole document: gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pgmraw -r150 \ To render a figure in grayscale: gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pnggray -sOutputFile=figure.png figure.pdf To render the same image at 300 dpi: gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=png16m -r300 \ To convert a figure to an image file: gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=png16m -dGraphicsAlphaBits=4 \ You'll be prompted to press return between pages. To view a file: gs -dSAFER -dBATCH document.pdf The details of how these work are described below. Ghostscript on unix-like systems type: gs. The command line to invoke Ghostscript isĮssentially the same on all systems, although the name of the executable Please refer to the documentation for those applications for using Ghostscript in other contexts. Ghostscript is also used as a general engine inside other applications (for viewing files for example). ![]() This document describes how to use the command line Ghostscript client. Appendix: Running Ghostscript with third-partyįor other information, see the Ghostscript.Appendix: Paper sizes known to Ghostscript. ![]() Using Ghostscript with overprinting and spot colors.Changing the installed default paper size.These documents do not specify the endianness, which is however big endian, as can be seen looking into a DVI file itself. ![]() It seems to be based on a TUGboat article of the same name from 1992, but which is much shorter. Like PDF, DVI uses a limited sort of machine language with termination guarantees that is not a full, Turing-complete programming language like PostScript.Īs of 2004 there is a compilation of the specifications a DVI driver must implement by the "TUG DVI Driver Standards Committee". (Both PostScript and PDF formats can either embed their fonts inside the documents.) For a DVI file to be printed or even properly previewed, the fonts it references must be already installed. LaTeX).ĭVI differs from PostScript and PDF in that it does not support any form of font embedding, but merely references external font name. TeX markup may be at least partially reverse-engineered from DVI files, although this process is unlikely to produce high-level constructs identical to those present in the original markup, especially if the original markup used high-level TeX extensions (e.g.
