Struct anl::ImplicitBrightContrast
[−]
[src]
pub struct ImplicitBrightContrast { /* fields omitted */ }The BrightContrast function provides a method for adjusting the brightness and contrast of the image. Contrast is adjusted relative to a specified threshold. Values greater than the threshold are adjust upward (brighter), while values below the threshold are adjusted downward (darker). (Note: The brightness and contrast correction provided by this function are additive, meaning that all values are brightened or darkened across the applicable range, unlike the Bias function, which lightens or darkens, but preserves the total range of the function.
