EQN2GRAPH(1) General Commands Manual EQN2GRAPH(1) NAME eqn2graph - convert an EQN equation into a cropped image SYNOPSIS eqn2graph [-format output-format] [convert-arguments] eqn2graph --help eqn2graph -v eqn2graph --version DESCRIPTION eqn2graph reads a one-line eqn(1) equation from the standard input and writes an image file, by default in Portable Network Graphics (PNG) format, to the standard output. The input EQN code should not be preceded by the .EQ macro that normally precedes it within groff(1) macros; nor do you need to have dollar-sign or other delimiters around the equation. Arguments not recognized by eqn2graph are passed to the ImageMagick or GraphicsMagick pro- gram convert(1). By specifying these, you can give your image a border, set the image's pixel density, or perform other useful transformations. The output image is clipped using convert's -trim option to the smallest possible bounding box that contains all the black pixels. OPTIONS -format output-format Write the image in output-format, which must be understood by convert; the default is PNG. --help Display a usage message and exit. -v --version Display version information and exit. ENVIRONMENT GROFF_TMPDIR TMPDIR TMP TEMP These environment variables are searched in the given order to determine the direc- tory where temporary files will be created. If none are set, /tmp is used. AUTHORS eqn2graph was written by Eric S. Raymond <esr AT thyrsus.com>, based on a recipe for pic2graph(1), by W. Richard Stevens.
