Resize a decoded raw image.
npm install --save resize-image-data
const resizeImageData = require('resize-image-data')
const result = resizeImageData(image, 128, 128, 'bilinear-interpolation')
console.log(result.width)
//=> 128
console.log(result.height)
//=> 128
console.log(result.data)
//=> Uint8ClampedArray [ ... ]
resizeImageData(image, width, height[, algorithm])
Resize the image to the supplied width and height, using the specified algorithm.
The image
argument should be a ImageData
instance, or any object with the following properties:
width: Number
- The width of the image, in pixelsheight: Number
- The height of the image, in pixelsdata: Buffer | TypedArray | Array
- The image data, stored as raw pixel data in the RGBA orderThe following algorithms is currently supported:
nearest-neighbor
bilinear-interpolation
If no algorithm is provided, it will currently default to bilinear-interpolation
. This may however change in any subsequent release, so don't count on it being stable between even minor and patch releases. The goal is to provide the "best" experience when not supplying an algorithm, which could mean different default algorithms depending wether we are scaling up or down.
Returns an ImageData
instance.
rotate-image-data
