interpolation algorithm

Variants

INTER_NEAREST = 0

nearest neighbor interpolation

INTER_LINEAR = 1

bilinear interpolation

INTER_CUBIC = 2

bicubic interpolation

INTER_AREA = 3

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_LANCZOS4 = 4

Lanczos interpolation over 8x8 neighborhood

INTER_LINEAR_EXACT = 5

Bit exact bilinear interpolation

INTER_NEAREST_EXACT = 6

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

INTER_MAX = 7

mask for interpolation codes

WARP_FILL_OUTLIERS = 8

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_INVERSE_MAP = 16

flag, inverse transformation

For example, linear_polar or log_polar transforms:

• flag is not set:
• flag is set:

WARP_RELATIVE_MAP = 32

flag, inverse transformation

For example, linear_polar or log_polar transforms:

• flag is not set:
• flag is set:

Trait Implementations

impl Clone for InterpolationFlags

fn clone(&self) -> InterpolationFlags

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InterpolationFlags

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<InterpolationFlags> for i32

fn from(v: InterpolationFlags) -> Self

Converts to this type from the input type.

impl PartialEq for InterpolationFlags

fn eq(&self, other: &InterpolationFlags) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<i32> for InterpolationFlags

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
