Before QgsMapRenderer was deprecated if we wanted to activate OTF we used code like this:

canvas = QgsMapCanvas()
canvas.mapRenderer().setProjectionsEnabled(True)

Currently, QgsMapRenderer is divided into two classes QgsMapSettings and QgsMapRendererJob. I did some research, but with no success. So how we can achieve the same now?

Not sure if this will be possible as according to one of the QGIS devs @ndawson in response to Feature request #11644:

"Disabling on the fly projection is no longer an option in QGIS 3.0"

  • So, you are saying that even this class is deprecated I can use it anyway?

    Thanks. That's what I was looking for, despite that it's not a good information (at least for me :) ).
