Description
Get the composite response curve LUT or one element of the curve.
-
Property type
-
A Variant value.
-
Syntax
-
object.Lut([Index])
The Lut Property syntax has these parts: |
| object | An expression evaluating to an object of type McLookupTable. | | Index | Optional. A Long value. long : Optional. A 0-based index indicating which element of the LUT is being read. Index = -1 indicates that the entire LUT is returned or supplied. By default Index = -1.
|
Remarks
The final response curve will be calculated by combining brightness, contrast, and gamma values, and the free-form LUT. This property returns a normalized response curve with a fixed size of 256 entries that respects only the Brightness, Contrast, Gamma, Freeform, and EnableResponse properties for THIS channel only. The intended purpose of this property is to support display of the curve resulting from the current LookupTable settings; when a LUT is desired for image display or conversion, the ExtendedLUT property should be used.
Notes
When getting this property, the return will contain either a single numerical value (0 <= Index < 256), or an array containing the entire response curve LUT (Index = -1). This array will contain integer values representing the response for each of 256 normalized pixel values.
