Class TLcdLookupTable

java.lang.Object
com.luciad.imaging.operator.util.TLcdLookupTable
public class TLcdLookupTable extends Object
An immutable lookup table.

The number of entries in the table is equal to the product of its sizes. Each entry has getComponentCount() components of a specific type. The values that lie between the table entries are computed depending on the ELcdInterpolationType.

The entries in the data buffer are first ordered along the first dimension, then along the second (if it exists), and so on. The components of an entry are consecutive.

You can use the builder to conveniently create a lookup table.

    • TLcdLookupTable

      public TLcdLookupTable(int[] aDimensions, int aComponentCount, TLcdLookupTable.ComponentType aComponentType, ELcdInterpolationType aInterpolation, Buffer aData)
      Creates a lookup table with user-defined settings.

      The data contains the the product of the aDimensions entries with each aComponentCount components of type aComponentType.

      Parameters:
      aDimensions - the size of the table along each dimension, the table must have at least 1 dimension and all sizes must be greater than 0
      aComponentCount - the number of components for a single entry
      aComponentType - the type of a component
      aInterpolation - the interpolation type for the components
      aData - the buffer that contains the data

    • getInterval

      public ILcdInterval getInterval()
      Returns the interval of values that should be mapped on the table data.
      Returns:
      the interval or null if it is unknown
