[mapserver-users] mapserver wrong scale computation

[Mario Jurcevic]

Hi,
I am trying to create an image with same size as the map extent, only by 
a scale factor of 500.
The mapserver scale computation gives 500.8989383487 scale.

If I set the image inch*72.129302863661 instead of default 72 the 
mapsever scale computed is
500.00127000041.

What is the correct value for resolution?

Regards,
