This program makes PNG and/or GIF graphics from DVI files as obtained from TeX and its relatives. Its benefits include:
– Speed. It offers very fast rendering of DVI as bitmap files, which makes it suitable for generating large amounts of images on-the-fly, as needed in preview-latex, WeBWorK and others;
– It does not read the postamble, so it can be started before TeX finishes. There is a --follow switch that makes dvipng wait at end-of-file for further output, unless it finds the POST marker that indicates the end of the DVI;
– Interactive query of options. dvipng can read options interactively through stdin, and all options are usable. It is even possible to change the input file through this interface.
– Support for PK, VF, PostScript Type1, and TrueType fonts, colour specials, and inclusion of PostScript, PNG, JPEG or GIF images.
