new_apphot

The new_apphot function is a non-class version of the CApphot:new method which creates and returns a new CApphot object.

Syntax

A = new_apphot()

Default constructor. The new CApphot A has all properties set to default values.

A = new_apphot( CApphot_old )

This is a copy constructor. The new CApphot A is initialized to the properties of CApphot_old. In place of CApphot and CApphot_old, use the actual name of the objects, such as A and A2.

Example

The following example shows the default constructor and destructor pair:

A = new_apphot()	-- create a new instance of A of the CApphot class.
...	-- other uses of the class go here, between new and delete.
A:delete()	-- deletes the object and its associated memory.

The next example shows the use of both constructors:

A = new_apphot(A1)	-- copy constructor, duplicates the data in A1
B = new_apphot()	-- default constructor
B.nRadius1 = 4.5	-- Set the value of nRadius1
B.nRadius2 = 12	-- Set the value of nRadius2
B.nRadius3 = 16	-- Set the value of nRadius3
bSuccess = B:Measure(I,x,y)	-- Measure object at (x,y) in CImage I
Printf("Mag = %lg", B.nMag )	-- result: Mag = 15.256
