IADLXDisplayGamma

Navigation: ADLX SDK References → ADLX Interfaces → Display

The IADLXDisplayGamma interface configures gamma correction on a display.

InterfaceId:	IADLXDisplayGamma
Smart Pointer Interface Name:	IADLXDisplayGammaPtr
Inherits:	IADLXInterface
Inherited By:	N/A

The IADLXDisplayGamma interface provides two types of gamma correction which are gamma ramp and gamma coefficient. Both gamma ramp and gamma coefficient have two sub-types: de-gamma and re-gamma.

Gamma ramp provides a Lookup Table (LUT) for the gamma correction, it applies the LUT with the assumption that all pixels are in sRGB space.
Re-Gamma coefficient uses the following non-linear formula:

C++

De-Gamma coefficient uses the following non-linear formula:

Code

C++

// Error reading file: [Errno 13] Permission denied: '..\\adlx\\drivers\\ADLX\\Samples\\cpp'
