M 6.6.8.6 Q16 Mac OSX Tiger

There are several problems:

1) The documentation on the options page says

-statistic type value

but it should really be

-statistic type WidthxHeight

I can change that if you want?


2) You don't define the option "Nonpeak". What does that do? If you tell me, I can change the documents, if you want.

3) Min and Max produce the same result on my test and give a compare of 0

4) Mean and Median produce the same results on my test and give a compare of 0

Test image zelda3.png and WidthxHeight=9x9 also WidthxHeight=3x3

We can reproduce the problem you posted and will have a patch in ImageMagick 6.6.8-7 Beta by sometime tomorrow. Thanks.

Nonpeak is one off from the peak color in the neighborhood. It is typically used for noise reduction.
