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).

virtual::itk::LightObject::Pointer itk::ChainCodePath2D::CreateAnother ( ) 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::Object.

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
overridevirtual

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

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

Reimplemented from itk::ChainCodePath< 2 >.

std::string itk::ChainCodePath2D::GetChainCodeAsString ( ) 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
overridevirtual

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

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
