Description:
TexMaths is a LaTeX equation editor for LibreOffice
TexMaths generates SVG or PNG images from LaTeX equations, inserts them into the document, and the LaTeX source is stored alongside the image in the ODT format. TexMaths can be used to edit the source and regenerate the image, or one can unzip the ODT and extract the LaTeX source from the content.xml.
