==========

|
.. function:: PlaneStats(vnode clipa[, vnode clipb, int plane=0, string prop='PlaneStats'])
|

|

:module: std
|
||
|
|
|
||
|
|
This function calculates the min, max and average normalized value of all
|
||
|
|
the pixels in the specified *plane* and stores the values in the frame properties
|
||
|
|
named *prop*\ Min, *prop*\ Max and *prop*\ Average.
|
||
|
|
|
||
|
|
If *clipb* is supplied, the absolute normalized difference between the two clips
|
||
|
|
will be stored in *prop*\ Diff as well.
|
||
|
|
|
||
|
|
The normalization means that the average and the diff will always be floats
|
||
|
|
between 0 and 1, no matter what the input format is.
