Hi

One more question:
The script fails to export larger images (round about 12,000 x 30,000).
Either the image.save() function returns "False" or the written image is
empty.
I read, that QImage() has a sizelimitation of 32,768 x 32,768 pixel. But
this should not be the problem here, right?
Are there limitation for the QgsMapRenderer? Or is this a memory issue?
I tested on a laptop computer with 1GB RAM (with Ubuntu 11.04) and a Windows
machine with 4 GB RAM. Both with the result desrcribed above...

Any ideas?

Thanks for helping.

Cheers
Stefan
