Rotate

class Rotate(degrees: Float, interpolation: InterpolationType, renderingSpeed: RenderingSpeed, enableAntialiasing: Boolean) : ImagePreprocessorBase

This image preprocessor defines the Rotate operation.

It rotates the input image on degrees.

The final image quality depends on the following tunable parameters: interpolation, renderingSpeed, enableAntialiasing.

Constructors

Rotate

fun Rotate(degrees: Float = 90f, interpolation: InterpolationType = InterpolationType.BICUBIC, renderingSpeed: RenderingSpeed = RenderingSpeed.MEDIUM, enableAntialiasing: Boolean = true)

Functions

apply

open override fun apply(image: BufferedImage): BufferedImage

Transforms provided input image.

getOutputShape

open override fun getOutputShape(inputShape: ImageShape): ImageShape

Computes output image shape for the provided inputShape. Note that some input dimensions could equal to null, which means that they are undefined. This is useful for the operations with fixed output size not dependent on the input size.

Properties

degrees

var degrees: Float = 90f

The rotation angle.

enableAntialiasing

var enableAntialiasing: Boolean = true

The image will be cropped from the right by the given number of pixels.

interpolation

var interpolation: InterpolationType

Interpolation algorithm.

renderingSpeed

var renderingSpeed: RenderingSpeed

Speed of preprocessing.
