I am starting to learn PyQGIS and following tutorials online. However, I have QGIS 3.0 and most of the tutorials use QGIS version 2. I am trying to do a buffer on a point shapefile, but only have the code for Qgis 2. I have looked at the backwards incompatible changes (https://qgis.org/api/api_break.html) but cannot work out how to adjust the code. The 'GeometryAnalyzer' class, which contained the buffer function in Qgis 2 no longer exists, so I am not sure where to find it now. I am sure there is a simple solution..
The code for Qgis 2 as far as I know is as follows:
from qgis.analysis import QgsGeometryAnalzer layer = iface.activeLayer() QgsGeometryAnalyzer().buffer(layer, 'OutputFilePath/FileName.shp', 0.5, False, False, -1)
How can this be adjusted to Qgis 3?
