Tonemap

Computational photographyclassOpenCV 5.0.0
import { Tonemap } from '@banou/opencv-wasm'

Use after await initOpenCV(). See the initialization and named imports guide.

ARGUMENTSConstructor or factory
CLASSTonemap
RETURN TYPEOwned native handle
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Native object: release it with using or delete(). Factories can return null; check before calling methods. Inherits Algorithm.

Base class for tonemapping algorithms - tools that are used to map HDR image to 8-bit range.

Constructors and members

clone

Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.

clone(): this;
Returns

The this result.

process

Tonemap.process: Tonemaps image

process(src: Mat, dst: Mat): void;
src

source image - CV_32FC3 Mat (float 32 bits 3 channels)

dst

Output destination, filled by the native operation. destination image - CV_32FC3 Mat with values in [0, 1] range

getGamma

Return the gamma configured on this Tonemap object.

getGamma(): number;
Returns

The number result.

setGamma

Set the gamma used by this Tonemap object.

setGamma(gamma: number): void;
gamma

gamma argument (number).
