- Description
The TDx_DrawGammaControl::SetGammaRamp method will set the gamma information of the primary surface to the specified values.
If the method call fails, the OnError event will be triggered with one of the following values:
DDERR_EXCEPTION
DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS
DDERR_OUTOFMEMORY
- Parameters
Flags
The Flags parameter defines a flag indicating whether gamma calibration should be used.
The described effect applies when the flag is set.
-
DDSGR_CALIBRATE
Adjust the gamma settings to suit the physical display so that different systems will display the same result. Hardware support for gamma calibration must exist when using this flag. Support can be checked by using the TDx_Draw::GetCaps() method and checking the Caps2 property for the DDCAPS2_PRIMARYGAMMA flag.
The RampData parameter references a TDDGammaRamp component holding the new gamma values to be set for the primary surface.
