Look-up table in GigEVisionSDK
In the GigEVisionSDK the ImageProcAPI provides the programming interface for generating and modifying
look-up tables. The bit depth and image type supported are shown in Table 82. For a detailed description on
how to use the look-up table feature please refer to the GigEVisionSDK API Help located in the doc folder
of the GigEVisionSDK installation directory.
