Detailed Description

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

Import data from a standard C array into an itk::Image.

ImportImageFilter provides a mechanism for importing data into an itk::Image. ImportImageFilter is an image source, so it behaves like any other pipeline object.

This class is templated over the pixel type and the image dimension of the output image.

Member Function Documentation

template<typename TPixel, unsigned int VImageDimension = 2> virtual void itk::ImportImageFilter< TPixel, VImageDimension >::EnlargeOutputRequestedRegion (  DataObject *    output )  [protected, virtual]

This filter can only produce the amount of data that it is given, so we must override ProcessObject::EnlargeOutputRequestedRegion() (The default implementation of a source produces the amount of data requested. This source, however, can only produce what it is given.) See also: ProcessObject::EnlargeOutputRequestedRegion() Reimplemented from itk::ProcessObject.

template<typename TPixel, unsigned int VImageDimension = 2> virtual void itk::ImportImageFilter< TPixel, VImageDimension >::GenerateData (    )  [protected, virtual]

This filter does not actually "produce" any data, rather it "wraps" the user supplied data into an itk::Image. Reimplemented from itk::ImageSource< Image< TPixel, VImageDimension > >.

template<typename TPixel, unsigned int VImageDimension = 2> virtual void itk::ImportImageFilter< TPixel, VImageDimension >::GenerateOutputInformation (    )  [protected, virtual]

This is a source, so it must set the spacing, size, and largest possible region for the output image that it will produce. See also: ProcessObject::GenerateOutputInformation() Reimplemented from itk::ProcessObject.

template<typename TPixel, unsigned int VImageDimension = 2> virtual const char* itk::ImportImageFilter< TPixel, VImageDimension >::GetClassName (    )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::ImageSource< Image< TPixel, VImageDimension > >.

template<typename TPixel, unsigned int VImageDimension = 2> TPixel* itk::ImportImageFilter< TPixel, VImageDimension >::GetImportPointer (    )

Get the pointer from which the image data is imported.

template<typename TPixel, unsigned int VImageDimension = 2> virtual const double* itk::ImportImageFilter< TPixel, VImageDimension >::GetOrigin (    )  const [virtual]

Get the origin of the image. See also: SetOrigin()

template<typename TPixel, unsigned int VImageDimension = 2> const RegionType& itk::ImportImageFilter< TPixel, VImageDimension >::GetRegion (    )  const [inline]

Get the region object that defines the size and starting index for the imported image. This will serve as the LargestPossibleRegion, the BufferedRegion, and the RequestedRegion. See also: ImageRegion Definition at line 95 of file itkImportImageFilter.h.

template<typename TPixel, unsigned int VImageDimension = 2> virtual const double* itk::ImportImageFilter< TPixel, VImageDimension >::GetSpacing (    )  const [virtual]

Get the spacing (size of a pixel) of the image. See also: SetSpacing()

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

Method for creation through the object factory. Reimplemented from itk::ImageSource< Image< TPixel, VImageDimension > >.

template<typename TPixel, unsigned int VImageDimension = 2> void itk::ImportImageFilter< TPixel, VImageDimension >::PrintSelf (  std::ostream &    os, Indent    indent )  const [protected, virtual]

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::ProcessObject.

template<typename TPixel, unsigned int VImageDimension = 2> void itk::ImportImageFilter< TPixel, VImageDimension >::SetImportPointer (  TPixel *    ptr, unsigned long    num, bool    LetSourceManageMemory )

Set the pointer from which the image data is imported. "num" is the number of pixels in the block of memory. If "LetSourceManageMemory" is false, then the application retains the responsibility of freeing the memory for this image data. If "LetSourceManageMemory" is true, then this class will free the memory when this object is destroyed.

template<typename TPixel, unsigned int VImageDimension = 2> virtual void itk::ImportImageFilter< TPixel, VImageDimension >::SetOrigin (  const float    data[] )  [virtual]

Set the origin of the image. See also: GetOrigin()

template<typename TPixel, unsigned int VImageDimension = 2> virtual void itk::ImportImageFilter< TPixel, VImageDimension >::SetOrigin (  const double    data[] )  [virtual]

Set the origin of the image. See also: GetOrigin()

template<typename TPixel, unsigned int VImageDimension = 2> void itk::ImportImageFilter< TPixel, VImageDimension >::SetRegion (  const RegionType &    region )  [inline]

Set the region object that defines the size and starting index for the imported image. This will serve as the LargestPossibleRegion, the BufferedRegion, and the RequestedRegion. See also: ImageRegion Definition at line 88 of file itkImportImageFilter.h.

template<typename TPixel, unsigned int VImageDimension = 2> virtual void itk::ImportImageFilter< TPixel, VImageDimension >::SetSpacing (  const float    data[] )  [virtual]

Set the spacing (size of a pixel) of the image. See also: GetSpacing()

template<typename TPixel, unsigned int VImageDimension = 2> virtual void itk::ImportImageFilter< TPixel, VImageDimension >::SetSpacing (  const double    data[] )  [virtual]

Set the spacing (size of a pixel) of the image. See also: GetSpacing()
