Latest version IM 6.4.3-7 beta (as of today, Sun, Sep 14) Q16 Mac OSX Tiger.

Seems like alpha reporting has gone back to being backwards again (min > max)

Depth: 16/8-bit
Channel depth:
red: 1-bit
green: 1-bit
blue: 1-bit
alpha: 8-bit
Channel statistics:
red:
min: 0 (0)
max: 0 (0)
mean: 0 (0)
standard deviation: -0 (-0)
green:
min: 0 (0)
max: 0 (0)
mean: 0 (0)
standard deviation: -0 (-0)
blue:
min: 0 (0)
max: 0 (0)
mean: 0 (0)
standard deviation: -0 (-0)
alpha:
min: 255 (1)
max: 0 (0)
mean: 55.0361 (0.215828)
standard deviation: 103.896 (0.407436)
Alpha: none #0000000000000000


If this is alpha and not opacity, then min should be 0 (0) and max should be 255 (1). The values reported seem backwards again whether for alpha or opacity ---- min should not be larger than max.


Sorry if this is premature testing. Anthony just told me that you guys are still doing testing. If you want me to hold off testing on this beta until further notice, let me know.

No testing beta is a good thing. Ok, yet another patch in the Subversion trunk.
