public final int computeSample(int[] samples, int numSamples)
AreaFilterOperation
numSamples
samples, which will be stored
starting at offset 0
.
Normally, numSamples
is equal to AreaFilterOperation.getAreaWidth()
times AreaFilterOperation.getAreaHeight()
.
Near the border of the image you may get less samples.
Example: the top left sample of an image has only three neighbors (east, south-east and south),
so you will only get four samples (three neighbors and the sample itself).

samples
- the array holding the sample(s)numSamples
- number of samples in the array
