Member Function Documentation

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

virtual

Return whether or not the VideoIO can read from a camera

Implements itk::VideoIOBase.

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

virtual

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

Implements itk::ImageIOBase.

virtual bool itk::OpenCVVideoIO::CanWriteFile ( const char *  )

virtual

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

Implements itk::ImageIOBase.

virtual::itk::LightObject::Pointer itk::OpenCVVideoIO::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::LightProcessObject.

virtual void itk::OpenCVVideoIO::FinishReadingOrWriting ( )

virtual

Close the reader and writer and reset members

Implements itk::VideoIOBase.

virtual CameraIDType itk::OpenCVVideoIO::GetCameraIndex ( ) const

virtual

Get/Set the device index for reading from a camera.

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

virtual

Virtual accessor functions to be implemented in each derived class.

Implements itk::VideoIOBase.

virtual std::vector< double > itk::OpenCVVideoIO::GetDirection ( unsigned int  i ) const

inlinevirtual

Override Accessors to pass default values since OpenCV doesn't handle this type of meta data.

Open the writer if the reader is not open.

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

overrideprotectedvirtual

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::OpenCVVideoIO::Read ( void *  buffer )

virtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.
