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.
|
nMinValue = CStats:Min() |
On success,
returns the minimum value as a number.
On failure,
returns 0.
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 |
