ImageBase is the base class for the templated Image classes. ImageBase is templated over the dimension of the image. It provides the API and ivars that depend solely on the dimension of the image. ImageBase does not store any of the image (pixel) data. Storage for the pixels and the pixel access methods are defined in subclasses of ImageBase, namely Image and ImageAdaptor.
There are three sets of meta-data describing an image. These are "Region" objects that define a portion of an image via a starting index for the image array and a size. The ivar LargestPossibleRegion defines the size and starting index of the image dataset. The entire image dataset, however, may not be resident in memory. The region of the image that is resident in memory is defined by the "BufferedRegion". The Buffer is a contiguous block of memory. The third set of meta-data defines a region of interest, called the "RequestedRegion". The RequestedRegion is used by the pipeline execution model to define what a filter is requested to produce.

Direction typedef support. The Direction is a matix of direction cosines that specify the direction between samples. Reimplemented in itk::Image< TPixel, VImageDimension >, itk::OrientedImage< TPixel, VImageDimension >, itk::VectorImage< TPixel, VImageDimension >, itk::Image< VariableLengthVector< TPixelType >, VImageDimension >, itk::Image< GradientPixelType, itkGetStaticConstMacro(ImageDimension), itk::Image< BloxBoundaryPointPixel< VImageDimension >, VImageDimension >, itk::Image< TNode *, VImageDimension >, itk::Image< BloxBoundaryProfilePixel< VImageDimension >, VImageDimension >, itk::Image< VariableLengthVector< TPixel >, VImageDimension >, itk::Image< BloxCoreAtomPixel< dim >, VImageDimension >, itk::Image< TBloxPixelType, VImageDimension >, and itk::VectorImage< TPixelType, Dimension >.

Compute the index of the pixel at a specified offset from the beginning of the buffered region. Bounds checking is not performed. Thus, the computed index could be outside the BufferedRegion. To ensure a valid index, the parameter "offset" should be between 0 and the number of pixels in the BufferedRegion (the latter can be found using ImageRegion::GetNumberOfPixels()). |

Compute an offset from the beginning of the buffer for a pixel at the specified index. The index is not checked as to whether it is inside the current buffer, so the computed offset could conceivably be outside the buffer. If bounds checking is needed, one can call ImageRegion::IsInside(ind) on the BufferedRegion prior to calling ComputeOffset. Definition at line 252 of file itkImageBase.h. |

Calculate the offsets needed to move from one pixel to the next along a row, column, slice, volume, etc. These offsets are based on the size of the BufferedRegion. This should be called after the BufferedRegion is set. |

Get the direction cosines of the image. The direction cosines are vectors that point from one pixel to the next. For ImageBase and Image, the default direction is identity. |

Get the origin of the image. The origin is the geometric coordinates of the index (0,0). The value returned is a pointer to a double array. For ImageBase and Image, the default origin is 0. |

|
Get the spacing (size of a pixel) `of the image. The spacing is the geometric distance between image samples. The value returned is a pointer to a double array. For ImageBase and Image, the default data spacing is unity. |

Determine whether the RequestedRegion is outside of the BufferedRegion. This method returns true if the RequestedRegion is outside the BufferedRegion (true if at least one pixel is outside). This is used by the pipeline mechanism to determine whether a filter needs to re-execute in order to satisfy the current request. If the current RequestedRegion is already inside the BufferedRegion from the previous execution (and the current filter is up to date), then a given filter does not need to re-execute Reimplemented from itk::DataObject. |
