Laeqed 1.1

Laeqed is a Latex equation editor specifically targeted at producing PNG images of math equations for use on web pages.

Laeqed runs wherever Java and Latex runs, i.e. Linux, Windows, Mac...

The Latex equation, preamble, postamble and dvipng options are saved with the PNG as meta data. This means that you can reopen any equation created by Laeqed and edit it if necessary.

Here is a listing of the meta data saved with the metric equation seen in the above screenshot:
