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

overridevirtual

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

Implements itk::ImageIOBase.

virtual bool itk::VTKImageIO::CanStreamRead ( void )

overridevirtual

Determine if the ImageIO can stream reading from the current settings. Default is false. If this is queried after the header of the file has been read then it will indicate if that file can be streamed

Reimplemented from itk::StreamingImageIOBase.

virtual bool itk::VTKImageIO::CanStreamWrite ( void )

overridevirtual

Determine if the ImageIO can stream write from the current settings.

There are two types of non exclusive streaming: pasteing subregions, and iterative

Reimplemented from itk::StreamingImageIOBase.

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

overridevirtual

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

Implements itk::ImageIOBase.

virtual::itk::LightObject::Pointer itk::VTKImageIO::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.

std::string itk::VTKImageIO::GetComponentTypeAsString ( IOComponentType )

private

virtual SizeType itk::VTKImageIO::GetHeaderSize ( void ) const

returns the header size, if it is unknown it will return 0

Implements itk::StreamingImageIOBase.

SizeType itk::VTKImageIO::GetIORegionSizeInBytes ( ) const

private

Return the number of bytes in the IOregion.

SizeType itk::VTKImageIO::GetIORegionSizeInComponents ( ) const

private

Return the number of pixels times the number of components in the IOregion.

SizeType itk::VTKImageIO::GetIORegionSizeInPixels ( ) const

private

Return the number of pixels in the IOregion.

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

virtual

Run-time type information (and related methods).

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::StreamingImageIOBase.

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