I am trying to do offset curve of a line
my layer projection is ESPG:3857 WGS-84\pseudo-Mercator
lyr=iface.activeLayer()
geom=lyr.selectedFeatures()[0].geometry()
newgom=geom.offsetCurve(5,2,1,0.0001)
feat=QgsFeature(lyr.fields())
feat.setGeometry(newgom)
lyr.addFeature(feat)
it's creating new line but when i calculate distance its given 4.1(in ellipsoid) and 5(in Cartesian) i need 5 meters in ellipsoid how can i get?
