 com.sun.media.jai.opimage.ClampOpImage
| ClampOpImage | | final class ClampOpImage extends PointOpImage (Code) | | An OpImage implementing the "Clamp" operation.
This OpImage maps all the pixel values of an image
that are less than a lower bound to that lower bound value, and all that
are greater than a upper bound to that upper bound value. All pixel values
fall within these boundaries remain unchanged. The mapping is done on a
per-band basis.
Each of the lower bound and upper bound arrays may have only
one value in it. If that is the case, that value is applied to all bands.
The number of elements in each array has to be consistent, i.e. either
all arrays contain one element in them or all they have the same number
of elements that matches the number of bands of the source image.
