SDL_SetWindowGammaRamp
Use this function to set the gamma ramp for a window.
Contents
Syntax
int SDL_SetWindowGammaRamp(SDL_Window* window,
const Uint16* red,
const Uint16* green,
const Uint16* blue)
Function Parameters
window |
the window to change |
red |
a pointer to the 256 element array of 16-bit quantities filled in with the translation table for the red channel, or NULL |
green |
a pointer to the 256 element array of 16-bit quantities filled in with the translation table for the green channel, or NULL |
blue |
a pointer to the 256 element array of 16-bit quantities filled in with the translation table for the blue channel, or NULL |
Return Value
Returns 0 on success, or a negative error code on failure; call SDL_GetError() for more information.

Remarks
Set the gamma translation table for the red, green, and blue channels of the video hardware. Each table is an array of 256 16-bit quantities, representing a mapping between the input and output for that channel. The input is the index into the array, and the output is the 16-bit gamma value at that index, scaled to the output color precision.
