[Qgis-user] About QgsGeometry::buffer

[Tudorache, Marian]

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.


Thanks,
Marian
