Constructor and Destructor


o CATMathTransformation1D
public CATMathTransformation1D()
Constructs the identity 1D transformation.
t(x) = x .
o CATMathTransformation1D
public CATMathTransformation1D( iArray)
Constructs a 1D transformation.
t(x) = iArray[0]*x + iArray[1].
Parameters:
iArray
The array of the scale and shift coefficient.
o CATMathTransformation1D
public CATMathTransformation1D( iA,
iB)
Constructs a 1D transformation.
t(x) = iA*x + iB.
Parameters:
iA
The scale coefficient.
iB
The shift coefficient.
o CATMathTransformation1D
public CATMathTransformation1D( const iX0,
const iFx0,
const iX1,
const iFx1)
Deprecated:
V5R20 Set Creates the linear transformation that transforms ix0 into ifx0 and ix1 into ifx1.
ix0 must be different from ix1, but this is not checked.
o CATMathTransformation1D
public CATMathTransformation1D( const iTransfo1DToCopy)
Copy constructor.
o ~CATMathTransformation1D
public ~CATMathTransformation1D()

Methods


o Apply
public Apply( iParamToTransform)
Transforms a double.
Parameters:
iParamToTransform
The double to transform.
Returns:
The result of the transformation.
o GetCoef
public GetCoef( ioCoef)
Retrieves the coefficients.
Parameters:
ioCoef
The array (that must be already allocated).
t(x) = ioCoef[0]*x + ioCoef[1].
o GetMatrix1D
public GetMatrix1D()
o GetMatrix1D
public GetMatrix1D()
Returns the scale coefficient.
Returns:
The scale coefficient.
o GetVector1D
public GetVector1D()
o GetVector1D
public GetVector1D()
Returns the shift coefficient.
Returns:
The shift coefficient.
o Set
public Set( const iX0,
const iFx0,
const iX1,
const iFx1)
Creates the linear transformation that transforms iX0 into iFx0 and iX1 into iFx1.
Parameters:
iX0
Double.
iFx0
Image of iX0 by the requested transformation.
iX1
Double.
iFx1
Image of iX1 by the requested transformation.
Returns:
E_FAIL if iX0 is equal to iX1 but not iFx0 and iFx1, otherwise S_OK In case of failure, the computed transformation is the identity.
o SetCoef
public SetCoef( const iNewCoef)
Modifies the coefficients.
Parameters:
iNewCoef
The array of the new coefficients.
