#include <itkImageIOBase.h>

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.

pure virtual

◆ CanStreamRead()

virtual bool itk::ImageIOBase::CanStreamRead ( )
inlinevirtual

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 in itk::MetaImageIO, itk::VTKImageIO, and itk::StreamingImageIOBase.

Definition at line 442 of file itkImageIOBase.h.

◆ CanStreamWrite()

virtual bool itk::ImageIOBase::CanStreamWrite ( )
inlinevirtual

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

Reimplemented in itk::JPEG2000ImageIO, itk::MetaImageIO, itk::VTKImageIO, and itk::StreamingImageIOBase.

Definition at line 470 of file itkImageIOBase.h.

◆ CanWriteFile()

virtual bool itk::ImageIOBase::CanWriteFile ( const char *  )
pure virtual

◆ ComputeStrides()

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.

◆ ExpandRGBPaletteOn()

virtual void itk::ImageIOBase::ExpandRGBPaletteOn ( )
virtual

Set/Get a boolean to perform RGB palette expansion. If true, palette image is read as RGB, if false, palette image is read as Scalar+Palette. A RGB image is always read as RGB.

◆ GenerateStreamableReadRegionFromRequestedRegion()

virtual ImageIORegion itk::ImageIOBase::GenerateStreamableReadRegionFromRequestedRegion ( const ImageIORegion requested) const
virtual

Method for supporting streaming. Given a requested region, determine what could be the region that we can read from the file. This is called the streamable region, which will be equal or smaller than the LargestPossibleRegion (unless it was dimensionally clipped) and greater or equal to the RequestedRegion

the resulting IORegion may be a greater dimensions the requested IORegion, if the derived class is unable to read the requested region. For example if the file has a size of [ 10, 10, 10] but the requested region is [10, 10] the return may be 3 dimensions.

Reimplemented in itk::NiftiImageIO, itk::JPEG2000ImageIO, itk::MetaImageIO, and itk::StreamingImageIOBase.

◆ GetActualNumberOfSplitsForWriting()

virtual unsigned int itk::ImageIOBase::GetActualNumberOfSplitsForWriting ( unsigned int  numberOfRequestedSplits,
const ImageIORegion pasteRegion,
const ImageIORegion largestPossibleRegion 
)
virtual

Before this method is called all the configuration will be done, that is Streaming/PasteRegion/Compression/Filename etc If pasting is being used the number of requested splits is for that region not the largest. The derived ImageIO class should verify that the file is capable of being written with this configuration. If pasted is enabled and is not support or does not work with the file, then an exception should be thrown.

The default implementation depends on CanStreamWrite. If false then 1 is returned (unless pasting is indicated), so that the whole file will be updated in one region. If true then its assumed that any arbitrary region can be written to any file. So the users request will be respected. If a derived class has more restrictive conditions then they should be checked

Reimplemented in itk::MetaImageIO, and itk::StreamingImageIOBase.

◆ GetActualNumberOfSplitsForWritingCanStreamWrite()

virtual unsigned int itk::ImageIOBase::GetActualNumberOfSplitsForWritingCanStreamWrite ( unsigned int  numberOfRequestedSplits,
const ImageIORegion pasteRegion 
) const
protectedvirtual

an implementation of ImageRegionSplitter:GetNumberOfSplits

◆ GetByteOrder()

virtual IOByteOrderEnum 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

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

◆ SetByteOrder()

virtual void itk::ImageIOBase::SetByteOrder ( const IOByteOrderEnum  _arg)
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.
