interpolation algorithm

Variants

INTER_NEAREST

nearest neighbor interpolation

INTER_LINEAR

bilinear interpolation

INTER_CUBIC

bicubic interpolation

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_LANCZOS4

Lanczos interpolation over 8x8 neighborhood

INTER_LINEAR_EXACT

Bit exact bilinear interpolation

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_MAX

mask for interpolation codes

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_INVERSE_MAP

flag, inverse transformation

For example, #linearPolar or #logPolar transforms:

• flag is not set:
• flag is set:

Trait Implementations

impl Clone for InterpolationFlags

fn clone(&self) -> InterpolationFlags

Returns a copy 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 PartialEq<InterpolationFlags> for InterpolationFlags

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

This method tests for self and other values to be equal, and is used by ==.

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

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