EQN2GRAPH(1) General Commands Manual EQN2GRAPH(1) NAME eqn2graph - convert an EQN equation into a cropped image SYNOPSIS eqn2graph [ -unsafe ] [ -format fmt ] DESCRIPTION Reads an EQN equation (one line) as input; produces an image file (by default in Portable Network Graphics format) suitable for the Web as output. Your input EQN code should not have the .EQ/.EN preamble that that nor- mally precedes it within groff(1) macros; nor do you need to have dol- lar-sign or other delimiters around the equation. 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 eqn(1), groff(1), and the ImageMagick convert(1) pro- gram. These programs must be installed on your system and accessible on your $PATH for eqn2graph to work. OPTIONS -unsafe Run groff(1) in the `unsafe' mode enabling the PIC macro sh to execute arbitrary commands. The default is to forbid this. -format fmt Specify an output format; the default is PNG (Portable Network Graphics). Any format that convert(1) can emit is supported. Command-line switches and arguments not listed above are passed to con- vert(1). FILES /usr/local/share/groff/1.18.1/tmac/eqnrc The eqn(1) initialization file.
