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 de- fault in Portable Network Graphics format) suitable for the Web as output. Your input EQN code should not have the .EQ/.EN preamble that that normally precedes it within groff(1) macros; nor do you need to have dollar-sign or other delimiters around the equation. The output image will be a black-on-white graphic clipped to the smallest possible bounding box that contains all the black pixels. By specifying command-line options to be passed to convert(1) you can give it a border, set the background transparent, set the image's pixel density, or perform other useful transformations. This program uses eqn(1), groff(1), and the ImageMagick convert(1) program. 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 exe- cute 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.
