    pic2graph

    
    
    

    SYNOPSIS

           pic2graph [ -unsafe ] [ -format fmt ] [ -eqn delim ]
    
    
    

    DESCRIPTION

           Reads  a  PIC  program  as input; produces an image file (by default in
           Portable Network Graphics format) suitable for the Web as output.  Also
           translates  eqn(1)  constructs, so it can be used for generating images
           of mathematical formulae.
    
           PIC is a rather expressive graphics minilanguage suitable for producing
           box-and-arrow  diagrams of the kind frequently used in technical papers
           and textbooks.  The language is sufficiently flexible to be quite  use-
           ful  for  state charts, Petri-net diagrams, flow charts, simple circuit
           schematics, jumper layouts, and other kinds of  illustration  involving
           repetitive  uses  of  simple  geometric forms and splines.  Because PIC
           descriptions are procedural and object-based, they are both compact and
           easy to modify.
    
           The PIC language is fully documented in "Making Pictures With GNU PIC",
           a document which is part of the groff(1) distribution.
    
           Your input PIC code should not be wrapped with the .PS and  .PE  macros
           that normally guard it within groff(1) macros.
    
           The output image will be a black-on-white graphic clipped to the small-
           est possible bounding box that contains all the black pixels.  By spec-
           ifying  command-line options to be passed to convert(1) you can give it
           a border, set the background transparent, set the  image's  pixel  den-
           sity, or perform other useful transformations.
    
           This  program uses pic(1), eqn(1), groff(1), gs(1), and the ImageMagick
           convert(1) program.  These programs must be installed  on  your  system
           and accessible on your $PATH for pic2graph to work.
    
    
    

    OPTIONS

           -unsafe
                  Run  pic(1)  and  groff(1) in the 'unsafe' mode enabling the PIC
                  macro sh to execute arbitrary commands.  The default is to  for-
                  bid this.
    
           -format fmt
                  Specify  an  output format; the default is PNG (Portable Network
                  Graphics).  Any format that convert(1) can emit is supported.
    
           -eqn delim
                  Change the fencepost characters that delimit  eqn(1)  directives
                  ($ and $, by default).  This option requires an argument, but an
                  empty string is accepted as a directive to disable  eqn(1)  pro-
                  cessing.
    
           Command-line switches and arguments not listed above are passed to con-
           vert(1).
