      • data uri for base64 encoded image string
      • http url path string
      • file url path string
      • buffer of RGBA pixel byte data as Uint8Array, Uint8ClampedArray, ArrayBuffer, or Array<number>
      • ImageBitmapSource, which includes:
        • Blob
        • ImageData
        • HTMLCanvasElement or OffscreenCanvas
        • HTMLImageElement or SVGImageElement or HTMLVideoElement
        • ImageBitmap

      Parameters

      • img_src: AnyImageSource

        anything image representation that can be constructed into an ImageBitmap using constructImageBitmapSource

      • Optionalwidth: number

        when using Uint8Array, Uint8ClampedArray, ArrayBuffer, or Array<number> as img_src, you must necessarily provide the width of the image

      • Optionalcrop_rect: Rect

        specify a cropping rectangle

      • Optionalbitmap_options: ImageBitmapOptions

        these are ImageBitmapOptions that can be used for optionally cropping the img_src, changing its colorSpace, etc...

      • Optionalblob_options: ImageEncodeOptions

        specify type: ImageMIMEType and quality: number to encode your output Blob into

        Note

        note that when using Uint8Array, Uint8ClampedArray, ArrayBuffer, or Array<number>, you should provide a width as the second argument to this function. you can also provide an optional image element as the third argument to load the given img_src onto, otherwise a new one will be made.

      Returns Promise<ImageBlob>
