I often create graphics in OpenOffice.org Draw, containing vector graphics, text labels, with photos occasionally mixed in. OpenOffice.org supplies a variety of export formats. Is there any way to export the graphics from this software to a format that can be placed in a ConTeXt document, such that the text labels are rendered using the font choices and typography of ConTeXt?
Since OO Draw cannot write TikZ code directly, you will need an intermediate format. Basically there are two options, only one of them works.
ODG -> SVG -> Inkscape SVG -> TikZ: inkscape2tikz
Since OpenOffice Draw is capable of producing SVG output, you can open it in Inkscape (version 0.48 or later, any current version should do) and use the PDF+LaTeX export feature as suggested by this answer. The basic idea is that the drawing without text is exported as PDF, and the text portions are exported as TikZ code. This tutorial (also linked from the above answer) shows in detail how to do it. I'm not sure if it's possible to produce ConTeXt, though.
The inkscape2tikz extension doesn't help here. It seems to be unmaintained and produced various issues when I tried it on a small example:
ODG -> EPS -> PGF: eps2pgf
I haven't tried the tool, which is also the subject of one of the replies to PS-or-PDF to tikz converter? . However, this approach (and also ODG -> PDF -> PGF) is bound to fail, since the generated EPS/PDF do not contain the label text as entire string but rather as individual characters.
