Sets the contrast value of the raw image.
Syntax
HRESULT SetContrast(
[in] double Contrast
);
Parameters
[in] Contrast
Type: double
The contrast value of the raw image. The default value is the "as-shot" setting. The value range for contrast is 0.0 through 1.0. The 0.0 lower limit represents no contrast applied to the image, while the 1.0 upper limit represents the highest amount of contrast that can be applied.
Return value
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
The codec implementer must determine what the upper range value represents and must determine how to map the value to their image processing routines.
