Detailed Description

VideoIO object for reading and writing videos as a sequence of frame files.

This VideoIO treats a sequential list of file names as the frames of a video. The frames must be specified in a comma-separated list. Also, the SplitFileNames(...) static method is made public in order to allow the splitting functionality to be accessed publicly.

Member Function Documentation

virtual bool itk::FileListVideoIO::CanReadCamera ( CameraIDType  cameraID ) const

virtual

Return whether or not the VideoIO can read from a camera

Implements itk::VideoIOBase.

virtual bool itk::FileListVideoIO::CanReadFile ( const char *  )

virtual

Determine the file type. Returns true if this ImageIO can read the file specified.

Determine the file type. Returns true if this ImageIO can write the file specified.

Implements itk::ImageIOBase.

virtual::itk::LightObject::Pointer itk::FileListVideoIO::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::LightProcessObject.

virtual void itk::FileListVideoIO::FinishReadingOrWriting ( )

virtual

Close the reader and writer and reset members

Implements itk::VideoIOBase.

virtual FrameOffsetType itk::FileListVideoIO::GetCurrentFrame ( ) const

virtual

Accessor functions for video specific information

Accessor functions for video specific information

Implements itk::VideoIOBase.

virtual double itk::FileListVideoIO::GetSpacing ( unsigned int  i ) const

virtual

Override Accessors to pass through to internal image reader

Reimplemented from itk::ImageIOBase.

static Pointer itk::FileListVideoIO::New ( )

static

Method for creation through the object factory.

void itk::FileListVideoIO::OpenReader ( )

private

virtual void itk::FileListVideoIO::PrintSelf ( std::ostream &  os, Indent  indent  ) const

protectedvirtual

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.

Reimplemented from itk::VideoIOBase.

virtual void itk::FileListVideoIO::Read ( void *  buffer )

virtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

virtual void itk::FileListVideoIO::ReadImageInformation ( )

virtual

Set the spacing and dimension information for the set filename.

Implements itk::ImageIOBase.

void itk::FileListVideoIO::ResetMembers ( )

protected

Reset member variables to empty state closed

virtual void itk::FileListVideoIO::SetFileName ( const std::string &  fileList )

virtual

Override SetFileName to do parsing

virtual void itk::FileListVideoIO::SetFileName ( const char *  fileList )

virtual

Override SetFileName to do parsing

Reimplemented from itk::ImageIOBase.

virtual bool itk::FileListVideoIO::SetNextFrameToRead ( FrameOffsetType  frameNumber )

virtual

Set the next frame that should be read. Return true if you operation successful

Implements itk::VideoIOBase.

virtual void itk::FileListVideoIO::SetReadFromCamera ( )

virtual

virtual

Set Writer Parameters

Implements itk::VideoIOBase.

static std::vector<std::string> itk::FileListVideoIO::SplitFileNames ( const std::string &  fileList )

static

Split up the input file names – This is public so that places where FileListVideoIO is used can access the individual file names. This is mostly an issue for testing.

bool itk::FileListVideoIO::VerifyExtensions ( const std::vector< std::string > &  fileList ) const

protected

Verify that all file names in the have the same extension

virtual void itk::FileListVideoIO::Write ( const void *  buffer )

virtual
