CStats:Min

CStats:Min and CStats:MinXy

The Min method computes the minimum value for an array, CImage , or list of numbers. The array and list parameters must contain a mixture of numbers and strings that can be converted to numbers.

Syntax

nMinValue = CStats:Min( CImage, CRect )

nMinValue = CStats:Min( CImage )

nMinValue = CStats:Min( table )

nMinValue = CStats:Min( n1, n2, n3, ... )

nMinValue, nX, nY = CStats:MinXy( CImage, CRect )

nMinValue, nX, nY = CStats:MinXy( CImage )

nMinValue, nX, nY = CStats:MinXy( table )

nMinValue, nX, nY = CStats:MinXy( n1, n2, n3, ... )

CRect is a bounding rectangle for the CImage object.

table is a 1-dimensional array containing numbers.

n1, n2, n3, ... are numbers or string values that can be converted to numbers.

On success, returns the minimum value and the x and y coordinates of the minimum value.

On failure, returns 0, 0, 0.

Example

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

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