This code really works @ ImageMagick-7.0.3-Q16 and ImageMagick-7.0.7-Q16 (Windows-64)

So, is there no solution inside IM at all ? Quite strange for such a powerful tool with all (trivial) data on the fingertips ...

The goal is to get value (file_size_in_bytes)/(image_height*image_width) in massive (Windows !) batch.
There are two problems (for me as a beginner):
- I found no -format option to get "always integer" filesize in bytes (%[size] give KB or MB values) to do math externally
- "obvios" calculations via ...

Thanks a lot !
So, a got the way to get image composite and channels info in-one-line is (in Windows BAT format)

identify -format "%%f %%[width] %%[height] %%[size] %%[colors] %%[entropy] %%[kurtosis] %%[mean] %%[skewness] %%[standard-deviation] " %1 >> %1.iinfo
convert %1 -channel red -format ...

What is the format option(-s) to get info from "Channel statistics:" block of -verbose option without image conversions
Such as (for example)
identify -format "%f %[skewness]\n" filename.jpg
but for red (for example) channel - not for all image statistics

Channel statistics:
