Detailed Description

template<typename TPixel, unsigned int VImageDimension = 2>
class itk::RawImageIO< TPixel, VImageDimension >

Read and write raw binary images.

This class reads and writes 2D or 3D images. Because raw data has little useful information built into the format, the user is responsible for specifying pixel type, dimensions, spacing, origin, header type, and so on. (Note: the pixel type and image dimension is defined via the template parameter.)

Member Function Documentation

template<typename TPixel , unsigned int VImageDimension = 2>
virtual bool itk::RawImageIO< TPixel, VImageDimension >::CanReadFile ( const char *  )
inlineoverridevirtual

Determine the file type. Returns true if this ImageIOBase can read the file specified. Always returns false because we don't want to use this reader unless absolutely sure (i.e., manual ImageIO creation).

Implements itk::ImageIOBase.

Definition at line 101 of file itkRawImageIO.h.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual bool itk::RawImageIO< TPixel, VImageDimension >::CanWriteFile ( const char *  )
overridevirtual

Returns true if this ImageIO can write the specified file. False is only returned when the file name is not specified. Otherwise true is always returned.

Implements itk::ImageIOBase.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual::itk::LightObject::Pointer itk::RawImageIO< TPixel, VImageDimension >::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.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual unsigned long itk::RawImageIO< TPixel, VImageDimension >::GetFileDimensionality ( ) const
virtual

The number of dimensions stored in a file. Defaults to two. If two, each file contains one "slice". If three, each file will contain one "volume".

template<typename TPixel , unsigned int VImageDimension = 2>
SizeValueType itk::RawImageIO< TPixel, VImageDimension >::GetHeaderSize ( )
template<typename TPixel , unsigned int VImageDimension = 2>
virtual const unsigned short& itk::RawImageIO< TPixel, VImageDimension >::GetImageMask ( ) const
virtual

Set/Get the Data mask.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual const char* itk::RawImageIO< TPixel, VImageDimension >::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods).

Reimplemented from itk::ImageIOBase.

template<typename TPixel , unsigned int VImageDimension = 2>
static Pointer itk::RawImageIO< TPixel, VImageDimension >::New ( )
static

Method for creation through the object factory.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual void itk::RawImageIO< TPixel, VImageDimension >::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::ImageIOBase.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual void itk::RawImageIO< TPixel, VImageDimension >::Read ( void *  buffer)
overridevirtual

Reads the data from disk into the memory buffer provided.

Implements itk::ImageIOBase.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual void itk::RawImageIO< TPixel, VImageDimension >::ReadHeader ( const std::string  = std::string())
inlinevirtual

Read a file's header to determine image dimensions, etc.

Definition at line 121 of file itkRawImageIO.h.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual void itk::RawImageIO< TPixel, VImageDimension >::ReadImageInformation ( )
inlineoverridevirtual

Binary files have no image information to read. This must be set by the user of the class.

Implements itk::ImageIOBase.

Definition at line 105 of file itkRawImageIO.h.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual void itk::RawImageIO< TPixel, VImageDimension >::SetFileDimensionality ( unsigned long  _arg)
virtual

The number of dimensions stored in a file. Defaults to two. If two, each file contains one "slice". If three, each file will contain one "volume".

template<typename TPixel , unsigned int VImageDimension = 2>
void itk::RawImageIO< TPixel, VImageDimension >::SetHeaderSize ( SizeValueType  size)

If the data is in the tail end of the file, you want to explicitly set the header size.

template<typename TPixel , unsigned int VImageDimension = 2>
void itk::RawImageIO< TPixel, VImageDimension >::SetImageMask ( unsigned long  val)
inline

Set/Get the Data mask.

Definition at line 112 of file itkRawImageIO.h.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual bool itk::RawImageIO< TPixel, VImageDimension >::SupportsDimension ( unsigned long  dim)
inlineoverridevirtual

The different types of ImageIO's can support data of varying dimensionality. For example, some file formats are strictly 2D while others can support 2D, 3D, or even n-D. This method returns true/false as to whether the ImageIO can support the dimension indicated.

Reimplemented from itk::ImageIOBase.

Definition at line 93 of file itkRawImageIO.h.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual void itk::RawImageIO< TPixel, VImageDimension >::Write ( const void *  buffer)
overridevirtual

Writes the data to disk from the memory buffer provided.

Implements itk::ImageIOBase.

template<typename TPixel , unsigned int VImageDimension = 2>
virtual void itk::RawImageIO< TPixel, VImageDimension >::WriteImageInformation ( void  )
inlineoverridevirtual

Binary files have no image information to read.
