Looking at identify -verbose info: on each image shows:

Alpha:
min: 255 (1)
max: 0 (0)

mean: 44.6997 (0.175293)
standard deviation: 96.9555 (0.380217)
kurtosis: 0.917287
skewness: -1.70801


This seems backwards to me for alpha and for opacity. Min should be 0 and max should be 255(1)

This seems to be fixed now in IM 6.6.1-4 Q16 Mac OSX Tiger.

Thanks.
