Detailed Description

Represent a 2D path as a sequence of connected image index offsets.

This class is intended to represent sequences of connected indices in a 2D image plane. It does so by storing the offset of each index from its immediately preceeding, connected, index using a standard Freeman code (1=up, 2=up to the right, and so on proceeding clockwise to 8=up to the left). The only image index stored directly is thatof the first index. ChainCodePath2D maps a 1D integer input (step number) to a 2D interger output (either an offset or an image index, depending on whether Evaluate or EvaluateToIndex is called).

Constructor & Destructor Documentation


Member Function Documentation

void itk::ChainCodePath2D::ChangeStep ( InputType  position,
int  encodedStep 
) [inline]

Change the direction of a step in the chaincode

Definition at line 119 of file itkChainCodePath2D.h.

void itk::ChainCodePath2D::ChangeStep ( InputType  position,
OffsetType  step 
) [inline, virtual]

Change the direction of a step in the chaincode

Reimplemented from itk::ChainCodePath< 2 >.

Definition at line 126 of file itkChainCodePath2D.h.

virtual void itk::ChainCodePath2D::Clear ( void  ) [inline, virtual]

Remove all steps from the chain code

Reimplemented from itk::ChainCodePath< 2 >.

Definition at line 133 of file itkChainCodePath2D.h.

virtual::itk::LightObject::Pointer itk::ChainCodePath2D::CreateAnother ( void  ) const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::ChainCodePath< 2 >.

OffsetType itk::ChainCodePath2D::DecodeOffset ( int  encodedStep) const [inline, protected]

Definition at line 153 of file itkChainCodePath2D.h.

int itk::ChainCodePath2D::EncodeOffset ( OffsetType  step) const [inline, protected]

Encode and Decode between an offset and a Freeman code

Definition at line 148 of file itkChainCodePath2D.h.

virtual OutputType itk::ChainCodePath2D::Evaluate ( const InputType input) const [virtual]

Evaluate the chaincode for the offset at the specified path-position.

Reimplemented from itk::ChainCodePath< 2 >.

virtual IndexType itk::ChainCodePath2D::EvaluateToIndex ( const InputType input) const [virtual]

Like Evaluate(), but returns the index at the specified path-position.

Reimplemented from itk::ChainCodePath< 2 >.

std::string itk::ChainCodePath2D::GetChainCodeAsString ( void  ) const
virtual const char* itk::ChainCodePath2D::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::ChainCodePath< 2 >.

virtual OffsetType itk::ChainCodePath2D::IncrementInput ( InputType input) const [virtual]

Increment the input variable passed by reference and return the offset stored at the previous path-position. If the chaincode is unable to be incremented, input is not changed and an offset of zero is returned, which may be used to check for the end of the chain code.

Reimplemented from itk::ChainCodePath< 2 >.

void itk::ChainCodePath2D::InsertStep ( InputType  position,
int  encodedStep 
) [inline]

Insert a new step into the chaincode at a specified position

Definition at line 105 of file itkChainCodePath2D.h.

void itk::ChainCodePath2D::InsertStep ( InputType  position,
OffsetType  step 
) [inline, virtual]

Insert a new step into the chaincode at a specified position

Reimplemented from itk::ChainCodePath< 2 >.

Definition at line 112 of file itkChainCodePath2D.h.

static Pointer itk::ChainCodePath2D::New ( ) [static]

New() method for dynamic construction

Reimplemented from itk::ChainCodePath< 2 >.

How many steps in the chaincode?

Reimplemented from itk::ChainCodePath< 2 >.

Definition at line 102 of file itkChainCodePath2D.h.

void itk::ChainCodePath2D::operator= ( const Self ) [private]

Reimplemented from itk::ChainCodePath< 2 >.

void itk::ChainCodePath2D::PrintSelf ( std::ostream &  os,
Indent  indent 
) const [protected, virtual]

Method for grafting the content of one data object into another one. This method is intended to be overloaded by derived classes. Each one of them should use dynamic_casting in order to verify that the grafted object is actually of the same type as the class on which the Graft() method was invoked.

Reimplemented from itk::ChainCodePath< 2 >.
