Hi everyone, I have a question about how to use CADDigitize plugin from pyqgis.
1. I would like to get the active instance of this plugin from QgisInterface (iface). I understand when the plugin is installed there is a reference of this plugin recorded here (iface). Is it possible to do this?

You have some example on PostGis documentation (parameters are the same) http://postgis.net/docs/ST_Buffer.html QGis define this parameters in Settings->Options->Digitizing->Curve offset tool. You can get this parameters via QSettings : join = QSettings().value("Qgis/digitizing/offset_join_style", 0, type=int) quad = QSettings().value("Qgis/digitizing/offset_quad_seg", 8, type=int) endCap = quad miter = QSettings().value("Qgis/digitizing/offset_miter_limit", 5, type=int) Regards l.bartoletti Le 18/09/2015 23:12, Tudorache, Marian a écrit : Hi everyone, I would like to find more details about QgsGeometry::buffer with more styles. In QGIS API Documentation there are two version of the buffer: Simple version with distance and segments and with sytles. The one with styles is defines as: ( distance, segments, endCapStyle, joinStyle, mitreLimit ); I do not understand the followings parameters: endCapStyle: Round (1) / Flat (2) / Square (3) end cap style joinStyle: Round (1) / Mitre (2) / Bevel (3) join style mitreLimit: Limit on the mitre ratio used for very sharp corners Does someone has some examples or recommend a book where to find more details please? The QGIS API Documentation does not give me too much.
