Resize

class Resize(outputWidth: Int, outputHeight: Int, interpolation: InterpolationType, renderingSpeed: RenderingSpeed, enableAntialiasing: Boolean) : ImagePreprocessorBase

This image preprocessor defines the Resize operation.

Resize operations creates new image with the following sizes:

resizedWidth = outputWidth
resizedHeight = outputHeight

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

Constructors

Resize

fun Resize(outputWidth: Int = 100, outputHeight: Int = 100, interpolation: InterpolationType = InterpolationType.BILINEAR, 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

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.

outputHeight

var outputHeight: Int = 100

The output height.

outputWidth

var outputWidth: Int = 100

The output width.

renderingSpeed

var renderingSpeed: RenderingSpeed

Speed of preprocessing.
