Method AdjustTone

Namespace

Assembly

AdjustTone(ToneAdjustments)

Applies the photographic adjustment set (exposure, brightness, contrast, highlights, shadows, saturation, sharpness) and returns the result as a new ImageBuffer. The source is never modified.

public ImageBuffer AdjustTone(ImageBuffer.ToneAdjustments adjustments)

Parameters

adjustments ImageBuffer.ToneAdjustments

The settings to apply; neutral settings return an unmodified copy.

Returns

ImageBuffer

A new ImageBuffer holding the adjusted image.

Remarks

The engine is deterministic and built for speed: exposure, brightness and contrast compose into ONE 256-entry lookup table; highlights and shadows become a pair of luma-indexed affine tables; saturation pivots on each pixel's own luma. All of it runs in a single pass over the pixels. Sharpness, when requested, adds one separable 3x3 unsharp pass that leaves flat areas byte-exact.

RGB24 and RGBA32 sources keep their format (alpha, when present, passes through untouched); any other format is first converted to RGBA32.
