CStats:Min

CStats:Min

The Min method computes the minimum value inside a rectangular region of the image. The rectangle and image must have been previously initialized for the CStats object.

Syntax

nMinValue = CStats:Min()

On success, returns the minimum value as a number.
On failure, returns 0.

Example

Suppose a CImage named I and a CRect named R exist. The following script fragment returns the minimum value inside a rectangle on the image:

S = CStats:new()	-- create a CStats object
S:Init( I, R )	-- specify CImage and CRect to be measured
nVal = S:Min()	-- returns the minimum value
Printf("Min=%lg\n", nVal)	-- list the result
S:delete()	-- when done with S, remove it from memory
