This is probably a simple request but I cannot find a way around it:
how can I read from python the map canvas CRS?
I know how to set it up:
canvas = self.iface.mapCanvas()
canvas.mapRenderer().setProjectionsEnabled(True)
canvas.mapRenderer().setDestinationCrs(QgsCoordinateReferenceSystem(EPSG_CODE))
But I want to do that ONLY if I need it:
canvas = self.iface.mapCanvas()
canCRS = (????)
wgsCRS = QgsCoordinateReferenceSystem(4326)
bBox = canvas.extent()
if canCRS == wgsCRS:
# get get lat long of canvas extent
lon = bBox.xMinimum()
lat = bBox.yMinimum()
lonMax = bBox.xMaximum()
latMax = bBox.yMaximum()
return lon, lat, lonMax, latMax
else:
# set map canvas CRS and get lat long of the extent
canvas.mapRenderer().setProjectionsEnabled(True)
canvas.mapRenderer().setDestinationCrs(wgsCRS)
lon = bBox.xMinimum()
lat = bBox.yMinimum()
lonMax = bBox.xMaximum()
latMax = bBox.yMaximum()
return lon, lat, lonMax, latMax
How do I get the map canvas CRS in EPSG code so I can compare it with QgsCoordinateReferenceSystem(4326)? Which method should I use?

Try:
canvas.mapRenderer().destinationCrs().authid()
That will return the map canvases' current crs as an epsg code
