About TpX drawing tool

TpX is a simple graphical editor for inclusion graphics into TeX files. It can also be used as a standalone editor for vector graphics.

The output is a file (with extension .TpX) containing the drawing as TeX code or as a \includegraphics link to an external file created by the program. User can choose between several output formats. TpX saves its own data in TeX file comments so that the drawing could be loaded into TpX and edited again. This internal TpX format is based on XML and could be understood and edited easily.

The closest analog for TpX is a similar program jPicEdt.
