InterpolationFlags

Image processingclassOpenCV 5.0.0
import { InterpolationFlags } from '@banou/opencv-wasm'

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

ARGUMENTSConstructor or factory
CLASSInterpolationFlags
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.

interpolation algorithm

Constructors and members

static INTER_NEAREST

bilinear interpolation

INTER_NEAREST: InterpolationFlagsValue<0>,

static INTER_LINEAR

bilinear interpolation

INTER_LINEAR: InterpolationFlagsValue<1>,

static INTER_CUBIC

bicubic interpolation

INTER_CUBIC: InterpolationFlagsValue<2>,

static INTER_AREA

resampling using pixel area relation. It may be a preferred method for image decimation, as it gives moire'-free results. But when the image is zoomed, it is similar to the INTER_NEAREST method.

INTER_AREA: InterpolationFlagsValue<3>,

static INTER_LANCZOS4

Lanczos interpolation over 8x8 neighborhood

INTER_LANCZOS4: InterpolationFlagsValue<4>,

static INTER_LINEAR_EXACT

Bit exact bilinear interpolation

INTER_LINEAR_EXACT: InterpolationFlagsValue<5>,

static INTER_NEAREST_EXACT

Bit exact nearest neighbor interpolation. This will produce same results as the nearest neighbor method in PIL, scikit-image or Matlab.

INTER_NEAREST_EXACT: InterpolationFlagsValue<6>,

static INTER_MAX

mask for interpolation codes

INTER_MAX: InterpolationFlagsValue<7>,

static WARP_FILL_OUTLIERS

flag, fills all of the destination image pixels. If some of them correspond to outliers in the source image, they are set to zero

WARP_FILL_OUTLIERS: InterpolationFlagsValue<8>,

static WARP_INVERSE_MAP

flag, inverse transformation

WARP_INVERSE_MAP: InterpolationFlagsValue<16>,

static WARP_RELATIVE_MAP

warp relative map constant (32), defined by OpenCV for cv.

WARP_RELATIVE_MAP: InterpolationFlagsValue<32>

These signatures describe this package. Upstream documentation can mention optional backends that are absent from this build. Check runtime compatibility before choosing a backend or file format.
