Hello devs,<br><br>I'm working on a project to draw simple arc/curves lines to represent (a lot of ) flow between two points. <br>I think it's a good idea to use the new geometry type "CIRCULARSTRING" implemented in Postgis to store/edit the arc/curve, one problem ... <br>
QGIS can't actually draw curved lines...<br><br>Actually here my few and poor idea to resolve this problem :<br><br>> I use <span style="font-size: 10pt; "><span>Stefan
Ziegler QGIS plugin CADTOOLS to compute and draw any</span></span> WKT using the CIRCULARSTRING geometry type, with few point to limit the complexity of polylines generated<br><br>> I'm waiting for the next QGIS dev version, because it seems developper want to implement this function ( cf<a href="http://www.qgis.org/wiki/6._QGIS_Developer_Meeting_in_Zurich_2011"> QGIS Developer Meeting in Zurich 2011</a> or <a href="http://www.qgis.org/wiki/KCube-developer">http://www.qgis.org/wiki/KCube-developer</a> )<br>
<br>> I'm trying to develop (in python or it's only possible in C++ ?) a new drawing extension which implement one function to draw pure bezier or simple arc with CIRCULARSTRING geometry in input ?<br><br>So QGIS dev, what's your opinion about that, or your next plan if you have a roadmap to implement these functionnality ? <br clear="all">
If you want to develop this functionnality in this summer, i'm ok to help and debug the code with you ...<br><br>Ps: i have post a question in gis stackexchange, but no answer actually ...<br> <a href="http://gis.stackexchange.com/questions/12007/how-i-can-draw-or-edit-curved-lines-in-free-gis">http://gis.stackexchange.com/questions/12007/how-i-can-draw-or-edit-curved-lines-in-free-gis</a><br>
