scistag.imagestag.interpolation.InterpolationMethod

class InterpolationMethod(value)

Bases: Enum

Enumeration of image interpolation methods

Methods

to_cv	Maps the enum to the corresponding OpenCV type
to_pil	Maps the enum to the corresponding PIL type

Attributes

NEAREST	The pixel will be kept intact, the upscaled image has quite hard pixel edges and the downscaled image is noisy
LINEAR	Linear interpolation.
CUBIC	Cubic interpolation.
LANCZOS	The highest image rescaling quality available in cv2/PIL.

to_cv()

Maps the enum to the corresponding OpenCV type

Returns

The OpenCV constant

to_pil()

Maps the enum to the corresponding PIL type

Returns

The PIL constant

CUBIC = 2

Cubic interpolation. Matches the pixels of the source region to the image region and tries to preserve contours

LANCZOS = 3

The highest image rescaling quality available in cv2/PIL. Use this if performance is not the most important

LINEAR = 1

Linear interpolation. Mixes up to four colors based upon subpixel position.

NEAREST = 0

The pixel will be kept intact, the upscaled image has quite hard pixel edges and the downscaled image is noisy
