PIC2GRAPH(1) General Commands Manual PIC2GRAPH(1) NAME pic2graph - convert a PIC diagram into a cropped image SYNOPSIS pic2graph [-unsafe] [-format output-format] [-eqn delimiters] [convert-arguments] pic2graph --help pic2graph -v pic2graph --version DESCRIPTION pic2graph reads a pic(1) program from the standard input and writes an image file, by de- fault in Portable Network Graphics (PNG) format, to the standard output. It furthermore translates eqn(1) constructs, so it can be used for generating images of mathematical for- mulae. The input PIC code should not be wrapped with the .PS and .PE macros that normally guard it within groff(1) documents. Arguments not recognized by pic2graph 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 -eqn delimiters Use delimiters as the opening and closing characters that delimit eqn directives; the default is "$$". The option argument delimiters should be a two-character string, but an empty string ("") is accepted as a directive to disable eqn process- ing. -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. -unsafe Run groff in unsafe mode, enabling the PIC command sh to execute arbitrary Unix shell commands. The groff default is to forbid this. -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.
