public class AlgorithmRemoveSlices
extends AlgorithmBase

Algorithm verifies the z-th slice should be in included in the destination image, as defined in the list, remove. It copies the slice from the srcImage img to a buffer, and then from the buffer into the destination img. Copies the srcImage file info to a buffer and makes it conform to the new img, then copies it into the destImage file.

Note that an image is a set of slices; each slice is XxY, with Z slices.**(as of 1 Nov, does not yet process the more complicated DICOM images Completely)

Version:

v0.11 1 Nov 1999 (processes most images)

                                  ModelImage resultImage)

Copy important file information to resultant image structure.

Parameters:

image - Source image.
