Exporting current view as georeferenced image using PyQGIS

Question

I found Exporting composition as image using PyQGIS to export the current view as an image.

The following code works and was accepted as an answer.

c = iface.activeComposers()[0].composition()
image = c.printPageAsRaster(0)
image.save('output.png', 'png')

Sadly, the images produced by this code are not georeferenced, even if I use different image formats.

How is it possible to programmatically export current view as georeferenced image with QGIS?

You could use:

iface.mapCanvas().saveAsImage( "myGeoreferencedView.png" )

It exports both PNG and PNGw files. The latter is known as World file and contains coordinate information.

But not the crs, though maybe there is a gdal aux created as well? – mdsumner May 23 '16 at 13:28
Nope, only two files are generated. You can choose among several formats like TIF or TIFF, but you'll only get the raster and its corresponding World file. – Germán Carrillo May 23 '16 at 13:50
I requested GTiff some years ago, they may be ready for this now? It's a real lost opp – mdsumner May 23 '16 at 21:56
