Large area error

[Stansfield, William]

Hello all,

I have been performing some measurements on v. large images (~600mb tiffs) using ImageJ  on a Unix platform.
Using the measure command, I sometimes get Integrated Densities and Mean Gray values that are negative numbers.
The largest integrated value I seem to be able to obtain before it gets hokey is roughly 3.5 million.
Anyone have any thoughts?

Thanks very much in advance,

This bug will be fixed in ImageJ 1.38h.
