Examples of LookupTableJAI

com.lightcrafts.mediax.jai.LookupTableJAI
A lookup table object associated with the "Lookup" operation. The "Lookup" operation is described in com.lightcrafts.mediax.jai.operator.LookupDescriptor.
This object represents a single- or multi-banded table of any JAI supported data type. A single- or multi-banded source image of integral data types is passed through the table and transformed into a single- or multi-banded destination image of either integral and floating point data types.
The table data may cover only a subrange of the legal range of the input data type. The subrange is selected by means of an offset parameter which is to be subtracted from the input value before indexing into the table array. When only a subranged table is used with a source image, it is up to the user to make certain that the source image does not have pixel values outside of the table range. Otherwise, an ArrayIndexOutOfBoundsException can occur.
The table data is saved by reference only. @see com.lightcrafts.mediax.jai.operator.LookupDescriptor
