## Detailed Description

Read an image file and return a SimpleITK Image.

The reader can handle scalar images, and vector images. Pixel types such as RGB, RGBA are loaded as multi-component images with vector pixel types. Additionally, tensor images are loaded with the pixel type being a 1-d vector.

An interface is also provided to access the information from the underlying itk::ImageIO. This information can be loaded with the ReadImageInformation method. The information is from the itk::ImageIO interface. In some degenerate cases reading the bulk data may produce different results. Please see itk::ImageFileReader for more details.

Reading takes place by the ITK ImageIO factory mechanism. ITK contains many ImageIO classes which are responsible for reading separate file formats. By default, each ImageIO is asked if it "can read" the file, and the first one which "can read" the format is used. The list of available ImageIOs can be obtained using the GetRegisteredImageIOs method. The ImageIO used can be overridden with the SetImageIO method. This is useful in cases when multiple ImageIOs "can read" the file and the user wants to select a specific IO (not the first).

Examples
FilterProgressReporting/FilterProgressReporting.cxx, ITKIntegration/ITKIntegration.cxx, Segmentation/ConnectedThresholdImageFilter.cxx, Segmentation/NeighborhoodConnectedImageFilter.cxx, and SimpleGaussian/SimpleGaussian.cxx.

## ◆ MemberFunctionType

private

Image information methods updated via ReadImageInformation.

These accessor methods are valid after a call to ReadImageInformation or Execute. They contain the image information from the file via the itk::ImageIO. Information such as NumberOfComponents is based of the file format, so the number of components for internal types such as RGB or complex may not be described the same as with SimpleITK's Image interface.

The PixelID has been converted from the ITK type to SimpleITK's interpretation, and will not change when loaded as a SimpleITK Image.

## ◆ Execute()

overridevirtual

Set/Get The output PixelType of the image.

By default the value is sitkUnknown, which enable the output pixel type to be same as the file. If the pixel type is specified then the itk::ConvertPixelBuffer will be used to convert the pixels.

Query a meta-data dictionary for the existence of a key.

Read only the meta-data and image information in the file.

This method can be used to determine what the size and pixel type of an image file is without reading the whole image. Even if SimpleITK does not support an image of a certain dimension or type, the meta-information can still be read.

## ◆ SetExtractIndex()

 Self& itk::simple::ImageFileReader::SetExtractIndex ( const std::vector< int > & index )

starting index from the image on disk to extract.

Missing dimensions are treated the same as 0.

## ◆ SetExtractSize()

 Self& itk::simple::ImageFileReader::SetExtractSize ( const std::vector< unsigned int > & size )

size of image to extract from file.

By default the reader loads the entire image, this is specified when the size has zero length.

If specified, then the image returned from Execute will be of this size. If the ImageIO and file support reading just a region, then the reader will perform streaming.

The dimension of the image can be reduced by specifying a dimension's size as 0. For example a size of $[10,20,30,0,0]$ results in a 3D image with size of $[10,20,30]$. This enables reading a 5D image into a 3D image. If the length of the specified size is greater than the dimension of the image file, an exception will be generated. If the size's length is less than the image's dimension then the missing values are assumed to be zero.

When the dimension of the image is reduced, the direction cosine matrix will be set to the identity. However, the spacing for the selected axis will remain. The matrix from the file can still be obtained by ImageFileReader::GetDirection.

## ◆ SetFileName()

 Self& itk::simple::ImageFileReader::SetFileName ( const std::string & fn )

## ◆ ToString()

overridevirtual

Print ourselves to string

Reimplemented from itk::simple::ProcessObject.

## ◆ UpdateImageInformationFromImageIO()

 void itk::simple::ImageFileReader::UpdateImageInformationFromImageIO ( const itk::ImageIOBase * iobase )
protected

Internal method which update's this classes stored meta-data and image information.
