[mapserver-users] Scalebar vs Numeric scale

[Rui Gomes]

Hi. I find a resolution to get the dpi.

The answer is in this forum topic:

Use a hidden css div and a width 1 inch. Then use javascript (or
other) to get the offsetWidth (in pixel). The number of pixel is the
dpi resolution.

I don know if is the best answer but works
