#include <itkConstantBoundaryCondition.h>
This boundary condition returns a constant value for out-of-bounds image pixels.
For example, invoking this function object with a constant value of zero (the default) on each out-of-bounds element of a 7x5 iterator that masks a region at an image corner (iterator is centered on the 2):
* * * * * * * * * * * * * * * * 1 2 3 4 5 (where * denotes pixels that lie * * 3 3 5 5 6 outside of the image boundary) * * 4 4 6 7 8
would produce the following neighborhood of values:
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 2 3 4 5 0 0 3 3 5 5 6 0 0 4 4 6 7 8

Get the value of the constant.

virtual |
Determines the necessary input region for the output region. For this boundary condition, only the intersection of the largest possible image region and the output requested region is needed.
inputLargestPossibleRegion | Largest possible region of the input image. |
outputRequestedRegion | The output requested region. |

virtual |
Returns a value for a given pixel at an index. If the index is inside the bounds of the input image, then the pixel value is obtained from the input image. Otherwise, the constant value is returned.
index | The index of the desired pixel. |
image | The image from which pixel values should be determined. |
