I have exported a slide from Pannoramic viewer with magnification set to 1:2
I get an error if I try to view this slide using the openslide-python interface with the deepzoom-server
"Level 0 has non-zero image concat factor".
The slide is shown as the jpeg in the .mrxs file, but properties do not appear, and zooming is is severley limited

And true enough: the [LAYER_0_LEVEL_0_SECTION] section of the slidedat.ini has a key IMAGE_CONCAT_FACTOR = 1
If I change this key to 0, the error does not appear, but the slide shows erratic behaviour.

The resulting slide does work in the Pannoramic viewer, and in Aperio Scanscope software.

I'm happy to provide examples if needed
