Parent Classes:

RCHandleAC

Methods:

FastFourierTrans2dC(): Default constructor
This creates an invalid handle. You can remove this if you always want to create a full object.
FastFourierTrans2dC(istream & in): Stream constructor
This creates a new instance of the class from an input stream.
FastFourierTrans2dC(const ByteImageC & image): Construct from a ByteImage
FastFourierTrans2dC(const ImageC<ComplexC> & image): Construct from a complex image
FastFourierTrans2dC(const DoubleImageC & image): Construct from a double image
FastFourierTrans2dC(const ImageC<DoubleImageValueT> & image): Construct from a ImageC double image
FastFourierTrans2dC(const IntImageC & image): Construct from an int image
void ApplyForward(): Apply the forward transform
void ApplyBackward(): Apply the backward transform to internally stored complex image
void SetTransformImage(const ImageC<ComplexC> & image): Change the image held by transform
ImageC<ComplexC> TransformImage() const: Access to complex transformed image
ImageC<ComplexC> InputImage() const: Access to complex input image
DoubleImageC Re(BooleanT tr = FORWARD) const: Return the real part of (input || transform)
DoubleImageC Im(BooleanT tr = FORWARD) const: Return the imaginary part of (input || transform)
void Shift(): Shifts DC component to image centre
DoubleImageC PowerSpectrum() const: Returns the power spectrum of the transform Friends -------
ostream & operator<<(ostream & s,const FastFourierTrans2dC & out): output stream operator
istream & operator>>(istream & s,FastFourierTrans2dC & in): input stream operator

#include "amma/RCHandleA.hh"

RCAbstractC Abstract(): Create an abstract handle to this object.
BooleanT IsHandleType(const DT &) const: Is handle of given type ?
void CheckHandleType(const DT & dummy) const: Check handle type. Throw an expception if not.
BooleanT Save(ostream & out) const: Save to ostream.
RCHandleAC<FastFourierTrans2dBodyC> Copy() const: Creat a deep copy of this object.
protected:

#include "amma/RCHandle.hh"

BooleanT IsValid() const: Check its a valid handle.
BooleanT IsValidObject() const: Check its a valid handle, and that the object is pointed to is also valid.
RCHandleC<FastFourierTrans2dBodyC> & operator=(const RCHandleC<FastFourierTrans2dBodyC> & oth): Assignment.
BooleanT operator==(const RCHandleC<FastFourierTrans2dBodyC> & oth) const: Comparison operator.
BooleanT operator!=(const RCHandleC<FastFourierTrans2dBodyC> & oth) const: Comparison operator.
UIntT Hash() const: Hash function.x
BooleanT IsConst() const: Is object constant ?
BooleanT IsNotConst() const: Is object not constant ?
void SetConst(void) const: Lock the object.
This is const as a convience though it actual modified the object, often object you wish to ensure are constant already have const set. protected:
void Invalidate(): Turn this into an invalid handle.
FastFourierTrans2dBodyC & Body(): Direct access to body.
const FastFourierTrans2dBodyC & Body() const: Constant access to body.
