flag that indicates whether to enable the LUT |
Enables or disables the use of LUT.
Parameter | Description | |
bEnable | Flag that indicates when the LUT is used. Possible values are | |
Value | Meaning | |
TRUE | The LUT is used in all image processing functions, including save. (default). | |
FALSE | The LUT is used only when painting. It is ignored when an image processing function is applied or when a file is saved. |
