Inkscape is an incredible piece of software, but maybe you should better test with e.g. Firefox, since there are *many* SVGs out there which only display fine in the almighty Inkscape. (Could you attach the example SVG? It looks simple enough to serve as a testcase.) > However, the problem seems to be that the Qt SVG renderer simply > doesn't support clipping paths, period. That's an unfortunate limitation, indeed. :-( > Furthermore, they seem to > have decided they won't fix this, as the bug was closed with "won't > fix": > > http://bugreports.qt.nokia.com/browse/QTBUG-1865 In this older tracker item (before migration), you can see that the "Won't Fix" was later changed to "Deferred", now "Expired": http://qt.nokia.com/developer/task-tracker/index_html?method=entry&id=204966 That at least does not look like Nokia's official policy is that this won't get fixed. Anyhow, I am not so sure I fully understand the situation. AFAICS, there are two separate issues here: a) generation of the SVG b) SVG rendering Even if Qt's renderer does not support clipping, what does that have to do with a) (which is relevant for ipython export)? Does MPL use Qt for SVG export? ('Cause the tracker item is about QSvgGenerator, a QPaintDevice for *generating* SVGs.) I wonder why QSvgGenerator is not fixed even without clipping support in Qt's SVG renderer.. I can understand if they say "we want to be able to render what we produce", but in this case this introduces seemingly unnecessary limitations. (BTW: The viewbox will not help, this only sets a global SVG 'viewbox' property, which is not related to path clipping at all.) Have a nice day, Hans PS: Here are the current docs; I could not find a word about clipping in them: http://doc.qt.nokia.com/4.7/qtsvg.html http://doc.qt.nokia.com/4.7/qsvggenerator.html ------------------------------------------------------------------------------ Beautiful is writing same markup.
