Class ImageProcessor

API for image processing.

*

  • Required licence feature(s): ImageProcessing.

Example

Since the class is backed by native resources and implements AsyncDisposable it's highly recommended to use the await using syntax when an instance is created to ensure the resource is disposed automatically:

await using instance = await ImageProcessor.create(...);

Alternatively, one can explicitly call dispose method to release the native resource. If neither is used, the resource will be released when the instance is garbage collected which is not recommended.

Implements

  • AsyncDisposable

Methods

[asyncDispose] applyFilter crop dispose resize rotate create

Methods

[asyncDispose]

  • [asyncDispose](): Promise<void>

  • Returns Promise<void>

applyFilter

  • applyFilter(image, filter): Promise<ImageRef>

  • Applies given filter to the given image.

    Parameters

    Returns Promise<ImageRef>

    The result of the filter application.

crop

  • crop(image, quad): Promise<ImageRef>

  • Crops the given image to the given quadrilateral.

    Parameters

    • image: ImageRef

      The image to crop.

    • quad: Point[]

      The quadrilateral of normalized points to crop.

    Returns Promise<ImageRef>

    Cropped image.

dispose

  • dispose(): Promise<void>

  • As the instance is backed by a native resource, it should be disposed when it is no longer needed. This method will release the native resource. As a recommended alternative since the class implements AsyncDisposable one can use 'await using' syntax to ensure the resource is disposed of automatically. If neither is used, the resource will be released when the instance is garbage collected which is not recommended.

    Returns Promise<void>

    A promise that resolves when the instance is disposed.

resize

  • resize(image, size): Promise<ImageRef>

  • Resizes the given image to the given size.

    Parameters

    • image: ImageRef

      The image to resize

    • size: number

      Size of the longer side of the image.

    Returns Promise<ImageRef>

    Resized image.

rotate

  • rotate(image, rotation): Promise<ImageRef>

  • Rotates the given image by the given angle.

    Parameters

    Returns Promise<ImageRef>

    Rotated image.
