#include <itkExpandImageFilter.h>
Expand the size of an image by an integer factor in each dimension.
ExpandImageFilter increases the size of an image by an integer factor in each dimension using a interpolation method. The output image size in each dimension is given by:
OutputSize[j] = InputSize[j] * ExpandFactors[j]
The output values are obtained by interpolating the input image. The default interpolation type used is the LinearInterpolateImageFunction. The user can specify a particular interpolation function via SetInterpolator(). Note that the input interpolator must derive from base class InterpolateImageFunction.
This filter will produce an output with different pixel spacing that its input image such that:
OutputSpacing[j] = InputSpacing[j] / ExpandFactors[j]
The filter is templated over the input image type and the output image type.
This filter is implemented as a multithreaded filter and supports streaming.
This filter assumes that the input and output image has the same number of dimensions.

This method is used to set the state of the filter before multi-threading.

ExpandImageFilter is implemented as a multithreaded filter. Therefore, this implementation provides a DynamicThreadedGenerateData() routine which is called for each processing thread. The output image data is allocated automatically by the superclass prior to calling DynamicThreadedGenerateData(). DynamicThreadedGenerateData can only write to the portion of the output image specified by the parameter "outputRegionForThread"

ExpandImageFilter needs a smaller input requested region than the output requested region. As such, ShrinkImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

ExpandImageFilter produces an image which is a different resolution and with a different pixel spacing than its input image. As such, ExpandImageFilter needs to provide an implementation for UpdateOutputInformation() in order to inform the pipeline execution model. The original documentation of this method is below.
