[Qgis-developer] Batch generation of map images with MTR

[Nathan Woodrow]

Hey Richard,

There is a new class you can use for the rendering because we now have MTR
you have to wait for the image, or listen for the done event.  The code is
pretty easy and you can see an example of me using it here:

 https://github.com/DMS-Aus/qgis2img/blob/master/qgis2img/render.py#L43

The basics are:

    job = QgsMapRendererParallelJob(settings)
    job.start()
    job.waitForFinished()
    image = job.renderedImage()

settings is a QgsMapSettings class which you can make or take from the
canvas using iface.mapCanvas().mapSetttings()

QgsMapSettings has a list of layers to render so you can update that
without changing the layers on the canvas, it's very handy.

Give that a try and see how you go.

- Nathan
