Pan large image failes

Helo! I try pan an image:

file Schillerstraße_53_zus.png
Schillerstraße_53_zus.png: PNG image data, 720 x 13504, 8-bit/color RGBA, non-interlaced
GBA, non-interlaced

I don't see any zooming in the preview-window, but whole image at once. Installed is Debian Squeeze. Thank you! Gennadiy

The video tutorials section of this web site has an example of panning across an image.

Ok, thank you; I move in this direction. With regards, Gennadiy
