in order to be able to use the drawing in reports and the like, exporting
the schema as a picture, as a png file with transparent background (no grid)

This requires server support, as client JS cannot achieve this. However, www sql
designer is mainly client-based. Therefore, I cannot do this (until someone 
wishes to
completely duplicate wwwsql functionality on server and is able to send a 
"patch").

there are multiple ways to achieve the thing.
* draw the whole thing on a <canvas> element, that can be right-clicked & saved
* generate an svg document
* generate a vml document

depending on the browser ;)

Most of the visual layout of WWWSQL is done via HTML+CSS (only connector lines 
are
vectors). Mimicking this in _any_ way (yes, including svg/vml/canvas 
approaches) is
basically duplicating the code - something I strongly opt against. Therefore, 
this
issue remains as "wontfix", until somebody insane enough submits a patch.

SVG could be generated by  iterating over the tables, rows and connectors and 
presenting a pop-up window 
where it could be copied from. No code duplication is necessary, as all object 
properties (colors, sizes, etc) will 
be copied verbatim from existing DOM. I will work on it -- eventually.

Keep in mind that this might be more difficult than you think. First, tables 
are HTML
and there is no trivial html <-> svg bijection available. Second, there is no 
SVG in
IE. Third, SVG lacks some features present in HTML+CSS, such as word/line 
wrapping -
SVG test just does not wrap.
