[Qgis-user] Buffer segments to approximate

[Andreas Neumann]

Hi,

Buffers for points are round. There are also round corners for 
line/polygon buffers, depending on the linecap styles and line join 
styles. QGIS and simple features can only display straight lines. The 
number of the segements to approximate means the higher the number, the 
more vertices you will have for a circle approximation.

See also http://postgis.net/docs/manual-2.1/ST_Buffer.html as an 
explanation for buffer styles and segments.
