CStats:MinPix

CStats:MinPix

The MinPix method returns the pixel coordinate of the minimum value inside a rectangular region of the image. The rectangle and image must have been previously initialized for the CStats object.

Syntax

x, y = CStats:MinPix()

x, y are the pixel coordinates of the minimum value, relative to 1,1.
On success, returns x, y coordinates as non-zero.
On failure, returns 0,0.

Example

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

S = CStats:new()	-- create a CStats object
S:Init( I, R )	-- specify CImage and CRect to measure
x, y = S:MinPix()	-- get the column and row of the minimum value
Printf("Min at %d,&d\n", x, y )	-- list the result
S:delete()	-- when done with S, remove it from memory
