I have the same problem by calculating hotspot positions on the my map
canvas.

for example if i use an 100x100px image with center of 53.112000,
6.992000 with span of 0.0040.
i thought top left corner was (center - (span/2)) in both directions
and bottom right was (center + (span/2))

this is not right? too bad :(

i know an exception is if the image was NOT 1:1 (100x100)...
if image is 240x320 the span is 240(100%, 0.0040) x 320(133.3%,
0.005332)

so its true what John Coryat says?... its not possible to get the
"real" coordinates when i use static maps ?

thx a lot

Benjamin
