   javax.media.jai.OperationDescriptorImpl
      javax.media.jai.operator.MaxDescriptor

MaxDescriptor
public class MaxDescriptor extends OperationDescriptorImpl (Code)
An OperationDescriptor describing the "Max" operation.

The Max operation takes two rendered or renderable images, and for every pair of pixels, one from each source image of the corresponding position and band, finds the maximum pixel value. No additional parameters are required.

The two sources may have different number of bands and/or data types. By default, the destination image bound is the intersection of the two source image bounds. If the two sources don't intersect, the destination will have a width and a height of 0. The number of bands of the destination image is the same as the least number of bands of the sources, and the data type is the biggest data type of the sources.

The destination pixel values are defined by the pseudocode:

 if (srcs[0][x][y][b] > srcs[1][x][y][b]) {
 dst[x][y][b] = srcs[0][x][y][b];
 } else {
 dst[x][y][b] = srcs[1][x][y][b];
 }
