====== Calculate Lookup Table 2 ======

===== Description =====

Computes a new lookup table by evaluating an algebraic or logical expression once for every key of a format lookup table.

This functor is obsolete; use [[Calculate Lookup Table Values]] or [[Calculate Lookup Table Keys And Values]] instead.

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Expression  | [[Image Expression Type]]  | Algebraic or logical expression used to compute each output value. Must be enclosed in square brackets ''[ ]'' in EGO Script.  |
| Format  | [[Lookup Table Type]]  | Lookup table whose keys define the format (and, by default, the key and value column names) of the output.  |

===== Optional Inputs =====

^ Name  ^ Type  ^ Description  ^ Default Value  ^
| Key Name  | [[Name Type]]  | Name given to the output's key column. If omitted, the corresponding name from Format is used. This is an advanced port.  | .none  |
| Value Name  | [[Name Type]]  | Name given to the output's value column. If omitted, the corresponding name from Format is used. This is an advanced port.  | .none  |

===== Outputs =====

^ Name  ^ Type  ^ Description  ^
| Result  | [[Lookup Table Type]]  | Computed output lookup table.  |

===== Group =====

[[Functor List#Lookup Table | Lookup Table]]

===== Notes =====

All operations are performed using the precision defined by ImageExpression::Value; the final result is then converted to LookupTable::Value.
