Detailed Description

Abstract superclass defines image IO interface.

ImageIOBase is a class that reads and/or writes image data of a particular format (such as PNG or raw binary). The ImageIOBase encapsulates both the reading and writing of data. The ImageIOBase is used by the ImageFileReader class (to read data) and the ImageFileWriter (to write data) into a single file. The ImageSeriesReader and ImageSeriesWriter classes are used to read and write data (in conjunction with ImageIOBase) when the data is represented by a series of files. Normally the user does not directly manipulate this class other than to instantiate it, set the FileName, and assign it to a ImageFileReader/ImageFileWriter or ImageSeriesReader/ImageSeriesWriter.

A Pluggable factory pattern is used this allows different kinds of readers to be registered (even at run time) without having to modify the code in this class.

Determine if the ImageIO can stream reading from this file. Default is false. Definition at line 208 of file itkImageIOBase.h.

virtual bool itk::ImageIOBase::CanStreamWrite  )  [inline, virtual]
 

Determine if the ImageIO can stream writing to this file. Default is false. Definition at line 226 of file itkImageIOBase.h.

virtual bool itk::ImageIOBase::CanWriteFile const char *   )  [pure virtual]
 

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

Implemented in itk::AnalyzeImageIO, itk::Brains2MaskImageIO, itk::DicomImageIO, itk::DICOMImageIO2, itk::GiplImageIO, itk::IPLCommonImageIO, itk::MetaImageIO, itk::PNGImageIO, itk::RawImageIO< TPixel, VImageDimension >, itk::StimulateImageIO, and itk::VTKImageIO.

void itk::ImageIOBase::ComputeStrides  )  [protected]
 

Calculates the different strides (distance from one thing to the next). Upon return, strides[0] = bytes to get to the next component of a pixel, strides[1] = bytes to get to the next pixel in x direction, strides[2] = bytes to get to the next row in y direction, strides[3] = bytes to get to the next slice in z direction, etc.

const std::type_info& itk::ImageIOBase::ConvertToTypeInfo IODataType   )  const [protected]
 

Utility methods for working with IODataType.

virtual ByteOrder itk::ImageIOBase::GetByteOrder  )  const [virtual]
 

These methods indicate the byte ordering of the file you are trying to read in. These methods will then either swap or not swap the bytes depending on the byte ordering of the machine it is being run on. For example, reading in a BigEndian file on a BigEndian machine will result in no swapping. Trying to read the same file on a LittleEndian machine will result in swapping. Note: most UNIX machines are BigEndian while PC's and VAX's are LittleEndian. So if the file you are reading in was generated on a VAX or PC, SetByteOrderToLittleEndian() otherwise SetByteOrderToBigEndian(). Some ImageIOBase subclasses ignore these methods.

virtual const char* itk::ImageIOBase::GetClassName  )  const [virtual]
 

Run-time type information (and related methods).

Reimplemented from itk::LightProcessObject.

Reimplemented in itk::AnalyzeImageIO, itk::Brains2MaskImageIO, itk::DicomImageIO, itk::DICOMImageIO2, itk::GE4ImageIO, itk::GE5ImageIO, itk::GEAdwImageIO, itk::GiplImageIO, itk::IPLCommonImageIO, itk::MetaImageIO, itk::PNGImageIO, itk::RawImageIO< TPixel, VImageDimension >, itk::SiemensVisionImageIO, itk::StimulateImageIO, and itk::VTKImageIO.

virtual const char* itk::ImageIOBase::GetFileName  )  const [virtual]
 

Set/Get the name of the file to be read.
