com.sun.media.jai.opimage.MaxOpImage
| MaxOpImage | | final class MaxOpImage extends PointOpImage (Code) | | An OpImage implementing the "Max" operation as
described in javax.media.jai.operator.MaxDescriptor.
This OpImage chooses the maximum pixel values of the
two source images on a per-band basis. In case the two source images
have different number of bands, the number of bands for the destination
image is the smaller band number of the two source images. That is
dstNumBands = Math.min(src1NumBands, src2NumBands).
In case the two source images have different data types, the data type
for the destination image is the higher data type of the two source
images.
The value of the pixel (x, y) in the destination image is defined as:
for (b = 0; b < numBands; b++) {
dst[y][x][b] = Math.max(src1[y][x][b], src2[y][x][b]);
}
