IM 6.4.3-9 Q16 Mac OSX

There may be a problem reporting color values in -verbose info:

convert -size 100x100 xc:"rgb(255,102,0)" test_color.png
identify -verbose test_color.png

Type: Palette
Endianess: Undefined
Colorspace: RGB
Depth: 16/4-bit
Channel depth:
red: 1-bit
green: 4-bit
blue: 1-bit
Channel statistics:
red:
min: 15 (1)
max: 15 (1)
mean: 15 (1)
standard deviation: -0 (-0)
green:
min: 6 (0.4)
max: 6 (0.4)
mean: 6 (0.4)
standard deviation: -0 (-0)
blue:
min: 0 (0)
max: 0 (0)
mean: 0 (0)
standard deviation: -0 (-0)
Histogram:
10000: (65535,26214, 0) #FFFF66660000 rgb(255,102,0)

Why are the raw (unnormalized) colors reported as 15,6,0 and not 65535,26214,0?

On a Q16 system, I would have expected raw (unnormalized) colors to be in the range 0-65535.

Am I missing something or has there been a change?

We have a fix for the problem you reported. It will be available sometime tomorrow in the Subversion trunk. Thanks.
