Images are templated over a pixel type (modeling the dependent variables), and a dimension (number of independent variables). The container for the pixel data is the ImportImageContainer.
Within the pixel container, images are modeled as arrays, defined by a start index and a size.
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, need 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.
[RegionIndex, RegionSize] C [BufferIndex, BufferSize] C [ImageIndex, ImageSize]
Pixels can be accessed direcly using the SetPixel() and GetPixel() methods or can be accessed via iterators. Begin() creates an iterator that can walk a specified region of a buffer.
The pixel type may be one of the native types; a Insight-defined class type such as Vector; or a user-defined type. Note that depending on the type of pixel that you use, the process objects (i.e., those filters processing data objects) may not operate on the image and/or pixel type. This becomes apparent at compile-time because operator overloading(for the pixel type) is not supported.
The data in an image is arranged in a 1D array as [][][][slice][row][col] with the column index varying most rapidly. The Index type reverses the order so that with Index[0] = col, Index[1] = row, Index[2] = slice, ...

Allocate the image memory. The image Dimension and Size must already been set. |

Copy information from the specified data set. This method is part of the pipeline execution model. By default, a ProcessObject will copy meta-data from the first input to all of its outputs. See ProcessObject::GenerateOutputInformation(). Each subclass of DataObject is responsible for being able to copy whatever meta-data it needs from from another DataObject. Image has more meta-data than its superclasses Image or ImageBase. Thus, it must provide its own version of CopyInformation() in order to set its Spacing and Origin to match the input parameter. This implementation of CopyInformation() casts the input parameter to an ImageBase. If successful, this method call GetSpacing() and GetOrigin() on its input (since all subclasses of ImageBase are guarenteed to respond to GetSpacing() and GetOrigin()). If "data" is another datatype, this method may not do anything. Reimplemented from itk::ImageBase< VImageDimension >. |
