Class ImageBuffer.ToneAdjustments

Namespace

LMKit.Media.Image

Assembly

LM-Kit.NET.dll

The settings consumed by AdjustTone(ToneAdjustments): the photographic adjustment set (exposure, brightness, contrast, highlights, shadows, saturation, sharpness). Every value is normalized to [-1, +1] (sharpness to [0, +1]) with 0 meaning "leave as is"; assignments outside the range clamp silently, so a UI slider can bind directly.

Properties

Brightness

Linear brightness offset over [-1, +1]; +1 lifts every channel by 100 levels, -1 lowers it by the same amount.

Contrast

Contrast over [-1, +1], pivoting on mid-grey (128): positive values push channels away from the pivot, negative values pull them toward it.

Exposure

Exposure in photographic stops over [-1, +1]: +1 doubles every channel value, -1 halves it, applied before every other setting.

Highlights

Highlight recovery/boost over [-1, +1], weighted by pixel luma so only the bright end of the image responds: negative values pull blown areas back, positive values push them further.

IsNeutral

Whether every setting is at its neutral value - in which case AdjustTone(ToneAdjustments) returns an unmodified copy.

Saturation

Saturation over [-1, +1], pivoting on each pixel's own luma: -1 is grayscale, +1 doubles the distance of every channel from the luma. Greys are a fixed point at any setting.

Shadows

Shadow lift/crush over [-1, +1], weighted by pixel luma so only the dark end of the image responds: positive values open the shadows, negative values deepen them.

Sharpness

Unsharp-mask strength over [0, +1]. Flat areas are left byte-exact; only real detail (where a pixel differs from its neighborhood) is amplified.
