An OperationDescriptor describing the "Divide" operation.
The Divide operation takes two rendered or renderable images,
and for every pair of pixels, one from each source image of the
corresponding position and band, divides the pixel from the first
source by the pixel from the second source. No additional parameters
are required for this operation.
In case of division by 0, if the numerator is 0, then the result
is set to 0; otherwise, the result is set to the maximum value
supported by the destination data type.
The two source images may have different number of bands and 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 default 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.
As a special case, if one of the source images has N bands (N >
1), the other source has 1 band, and an ImageLayout
hint is provided containing a destination SampleModel
with K bands (1 < K <= N), then the single band of the 1-banded
source will be divided by or into to each of the first K bands of
the N-band source.
If the result of the operation underflows/overflows the
minimum/maximum value supported by the destination data type, then
it will be clamped to the minimum/maximum value respectively.
The destination pixel values are defined by the pseudocode:
dst[x][y][dstBand] = srcs[0][x][y][src0Band]/srcs[1][x][y][src1Band];
