Clusters
Number of output clusters or colors in the output image.
Type
Flag that determines which initializing algorithm to use when choosing the initial centers for the clusters.
InCenters
If the Type is KMeans_UserDefined, InCenters should be a reference to an array of RasterColor values that represents the initial centers.
RasterColor[] InCenters should be null if Type is KMeans_Random or KMeans_Uniform. If Type is KMeans_UserDefined, RasterColor[] InCenters should be filled with the initial centers for the clusters.
