dvipng 1.14

Makes PNG or GIF graphics from DVI files
This program makes PNG and/or GIF graphics from DVI files as obtained from TeX and its relatives.

If GIF support is enabled, GIF output is chosen by using the `dvigif' binary or with the `--gif' option.

dvipng is intended to produce anti-aliased screen-resolution images as fast as is possible. The target audience is people who need to generate and regenerate many images again and again. The primary target is the preview-latex (X)Emacs package, a package to preview formulas from within (X)Emacs. Yes, you get to see your formulas in the (X)Emacs buffer, see `http://www.gnu.org/software/auctex/#preview-latex'.

Another example is WeBWorK, an internet-based method for delivering homework problems to students over the internet, giving students instant feedback as to whether or not their answers are correct, see `http://webwork.math.rochester.edu'.

Other applications may also benefit, like web applications as latex2html and WYSIWYG editors like LyX.

Main features:

  • Speed. It is a very fast bitmap-rendering code for DVI files. On a fairly low-end laptop, it takes less than a second to generate 150 one-formula images. This makes dvipng 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 EOF 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.
  • Supports PK, VF, PostScript Type1, and TrueType fonts, color specials and simple PostScript inclusion specials.

What's New in This Release:
  • This version changes raw PostScript processing to avoid the non-rendering PostScript specials created by hyperref.
  • A command-line switch to turn off raw PostScript rendering has been added.
  • Finally, a few bugs have been fixed, such as correct decoding of the -T switch, a CRLF bug when reading configuration files in Windows, and a few bugs associated with subprocesses.
