Math Plugin_en

With this Plugin for JSPWiki you can enter mathematical formulas in Latex syntax directly in the Wiki and display them as Gifs in a similar way like it is possible with the famous Wikipedia. Everything happens in Java - you do not need Latex or other non-java binaries.

The visualization of the formulas is most of the work. This is done by HotEnq, a Java Component of the Ruhr University Bochum, specialist area automatic control engineering and process computer science. Thank you at Professor Dr. Dr.-Ing. Christian Schmid for friendly permission.

For the generation of the GIF images the ACME.jar of the ACME Laboratories is used (Freeware).
