pic2graph reads a gpic(1) program from the standard input and writes an image file, by default in Portable Network Graphics (PNG) format, to the standard output. It furthermore translates geqn(1) constructs, so it can be used for generating images of mathematical formulae.
The input PIC code should not be wrapped with the .PS and .PE/.PF macros that normally guard it within groff(1) documents.
Arguments not recognized by pic2graph are passed to the ImageMagick or GraphicsMagick program 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.
--help displays a usage message, while -v and --version show version information; all exit afterward.
pic2graph was written by Eric S. Raymond, based on a recipe by W. Richard Stevens.
