Hello, so far no response...we had discussion with boemann, so I paste it here, maybe it will inspire somebody for some idea.
<irc-talk> (11:47:40 AM) boemann: LukasT: suggestion: paint fill and outline as two steps (11:48:13 AM) boemann: if say nostroke the just replace that part of the path with a move (11:49:04 AM) boemann: then you can still paint/fill like now but the disabled part is not drawn (12:03:52 PM) LukasT: boemann: what do you mean by replace that part of the path with move? (12:08:29 PM) boemann: like create a qpainterpath copy but where the disabled parts are nor drawn (12:10:16 PM) LukasT: boemann: how to create qpainterpath copy where the disabled parts are nor drawn? some pseudo code? (12:10:43 PM) boemann: well i have not looked at the code in detail (12:10:47 PM) boemann: or at all (12:11:08 PM) LukasT: boemann: but I want some pseudo code of :how to create qpainterpath copy where the disabled parts are nor drawn: (12:11:11 PM) boemann: but i assume you have some kind of generic path you create the qpainterpath from (12:11:22 PM) LukasT: boemann: we have KoSubpath (12:11:35 PM) LukasT: boemann: that is set of points which is converted to QPainterPath (12:11:57 PM) LukasT: and N KoSubpaths are converted to one QPainterPath so that fill rule can be evaluated (12:12:10 PM) boemann: right and then instead of adding that to the qpainterpath you just do a qpainterpath::moveTo() to the final position of that subpath (12:12:11 PM) LukasT: I tried to render the shape per subpath (12:12:41 PM) boemann: that way you still end up with one qpainterpath but with subparts disabled (12:13:04 PM) LukasT: boemann: but how that solves nostroke? nostroke means that the shape of the subpath is filled but the stroke is not there (12:13:29 PM) boemann: yes you need to paint in two steps (12:13:35 PM) boemann: first fill then stroke (12:13:46 PM) boemann: and create two different qpainterpaths (12:13:57 PM) boemann: for stroke moveTo should do (12:14:03 PM) LukasT: boemann: sounds like a good plan, I will try (12:14:18 PM) boemann: but for fill you might have to do a lineTo to get the right result (12:18:15 PM) LukasT: boemann: I think there might be a problem with rendering fill and stroke separately (12:18:23 PM) LukasT: boemann: the order of the shape subpaths (12:19:14 PM) LukasT: boemann: is important, some part (subpath) of the shape can cover part of the other subpath's outline (12:20:37 PM) boemann: hmm (12:20:47 PM) boemann: true (12:21:48 PM) boemann: in that case i think there is no other solution than to implement the fill and draw ourselves (12:22:08 PM) LukasT: that is complex task (12:22:40 PM) boemann: sure is (12:23:00 PM) boemann: better way would be to patch qt (12:23:21 PM) LukasT: yes (12:25:43 PM) boemann: i still think the nofill attribute on subpath level is flawed (12:25:49 PM) boemann: it just doesn't make sense (12:30:45 PM) LukasT: boemann: it's like injecting fill rule algorithm :) </irc-talk> These methods gave me some hope for the nofill, nostroke problem http://doc.qt.nokia.com/latest/qpainterpath.html#toFillPolygons http://doc.qt.nokia.com/latest/qpainterpath.html#toSubpathPolygons but I still haven't found what I'm looking for...(read in the melody of that U2 song) No solution found :-( Any ideas? _______________________________________________ calligra-devel mailing list calligra-devel@kde.org https://mail.kde.org/mailman/listinfo/calligra-devel
