Examples of javax.media.jai.RasterAccessor.clampDataArrays()

javax.media.jai.RasterAccessor.clampDataArrays()
Clamps data array values to a range that the underlying raster can deal with. For example, if the underlying raster stores data as bytes, but the samples are unpacked into integer arrays by the RasterAccessor for an operation, the operation will need to call clampDataArrays() so that the data in the int arrays is restricted to the range 0..255 before a setPixels() call is made on the underlying raster. Note that some operations (for example, lookup) can guarantee that their results don't need clamping so they can call RasterAccessor.copyDataToRaster() without first calling this function.
