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 preceding, 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 integer output (either an offset or an image index, depending on whether Evaluate or EvaluateToIndex is called).

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.

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.

std::string itk::ChainCodePath2D::GetChainCodeAsString ( void ) const

virtual const char* itk::ChainCodePath2D::GetNameOfClass ( ) const

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,

protectedvirtual

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.
