CFwhm:new

CFwhm:new

The new method constructs a new instance of a CFwhm object. The CFwhm class includes data members that control calculation of a FWHM value and its centroid position. Two different constructor overloads are available to create a new CFwhm and initialize the data members.

Syntax

F = CFwhm:new()

Creates a default CFwhm F with data members initialized to default values.

F = CFwhm:new( CFwhm )

This is a copy constructor. It creates a new CFwhm F initialized to the data members of the CFwhm argument. In place of CFwhm:, use the name of the actual object to be copied.

Remarks

Two overloads are provided for the CFwhm class. They create a default CFwhm and a copy of a CFwhm. If you pass something other than nil or another CFwhm—such as a string—then the default constructor is used.

Example

The following script fragment illustrates using the 2 constructors. All produce the same result:

F1 = CFwhm:new()	-- create CFwhm A and set values
F1:SetSign(false)	-- change the default (true)
F2 = CFwhm:new( F1 )	-- copy A to a new CFwhm B
Printf("F1 sign = %d", F1:GetSign() )	-- result: F1 sign = 0
Printf("F2 sign = %d", F2:GetSign() )	-- result: F2 sign = 0
