Detailed Description

Function Documentation

const GLFWgammaramp* glfwGetGammaRamp

(

GLFWmonitor *

monitor

)

This function retrieves the current gamma ramp of the specified monitor.

Parameters

[in]

monitor

The monitor to query.

Returns

The current gamma ramp, or NULL if an error occurred.

Note

The value arrays of the returned ramp are allocated and freed by GLFW. You should not free them yourself.

void glfwSetGamma	(	GLFWmonitor *	monitor,
		float	gamma
	)

This function generates a 256-element gamma ramp from the specified exponent and then calls glfwSetGammaRamp with it.

Parameters

[in]	monitor	The monitor whose gamma ramp to set.
[in]	gamma	The desired exponent.

void glfwSetGammaRamp	(	GLFWmonitor *	monitor,
		const GLFWgammaramp *	ramp
	)

This function sets the current gamma ramp for the specified monitor.

Parameters

[in]	monitor	The monitor whose gamma ramp to set.
[in]	ramp	The gamma ramp to use.

Note

Gamma ramp sizes other than 256 are not supported by all hardware.
