CRT Monitors.Due to an odd bit of engineering luck, the native gamma of a CRT is 2.5 — almost the inverse of our eyes. Values from a gamma-encoded file could therefore be sent straight to the screen and they would automatically be corrected and appear nearly OK. However, a small gamma...
SetDeviceGammaRamp 设置gamma 和 GetDeviceGammaRamp 读取gamma(如果返回false则不支持gamma) 交换链 iSwapChain 一般选0,Flags 为:D3DSGR_NO_CALIBRATION 和 D3DSGR_CALIBRATE 控制应用gamma坡道之前是否对其进行校正,校正保证显示更加连续,但处理速度慢。通常仅设置gamma一次,这样不需要校正。如果想不断调整gamma制作动...
Not all systems support gamma calibration. To determine whether it is supported, callManager.GetDeviceCapsand examine theDriverCapsmember of the returnedCapsstructure. If theDriverCaps.CanCalibrateGammaproperty is set totrue, gamma calibration is supported. ...
对于SetGammaRamp,第一个参数是 D3DSGR_CALIBRATE 或 D3DSGR_NO_CALIBRATION。 第二个参数 pRamp 是指向D3DGAMMARAMP结构的指针。D3DGAMMARAMP结构包含三个 256 个元素的 WORD 数组,每个数组包含红色、绿色和蓝色伽玛渐变。GetGammaRamp有一个参数,该参数将指针指向将使用当前伽玛斜坡填充的D3DGAMMARAMP类型。

and they would automatically be corrected and appear nearly OK. However, a small gamma correction of ~1/1.1 needs to be applied to achieve an overall display gamma of 2.2. This is usually already set by the manufacturer's default settings, but can also be set duringmonitor calibration. ...
