What does the values of cmyk-file histogramm mean?

Hi IM folks,


If I get the histogramm for an CMYK image with perlMagick, what does  
the resulting 5 values mean:
a) cmyk (0-255)+ opacity + counter
b) rgb + "unknown" + opacity + counter

0 0 247 0 0 4650 0 0 247 247 0 2750 247 0 247 0 0 250 247 0 247 247 0  
2250 0 247 247 0 0 100

I tend to say it is version a) - but who knows.


Remark:
Your stuff is stll one of the best - in my mind!
Thanks to you all

Alexander
