CStats:SetImage CStats:GetStatus

CStats:SetRect

The SetRect method assigns a CRect object to the CStats object. Statistics will be measured inside this rectangular region.

Syntax

CStats:SetRect( CRect )

 

Example

Suppose a CImage I holds a valid image and that a CRect R exists. The following script fragment initializes CStats for computing statistics inside the rectangle R on the image I:

 

S = CStats:new()

-- create a CStats object

S:SetImage( I )

-- specify the CImage to be measured

S:SetRect( R )

-- specify the CRect to be measured

mean, sdev = S:MeanSdev()

-- returns the mean and standard deviation

S:delete()

-- when done with S, remove it from memory

Remarks

CStats, Init, CRect, CImage
