Hi,

Very slow with bigger files

Hi Erel,
I tested the scrolling and magnifying with big files (11 MB jpg and 27 MB bmp) and it's very slow now. How can it be improved. Tested on a new computer (DualCore 2,2 GHz, 2 GB RAM, XP SP2). May be you can help?

Hi wolfgang,

Maybe it could be faster taking every time a smaller part of your map.
