Scales raw image data by 2x using the Super xBR algorithm. https://en.wikipedia.org/wiki/Image_scaling#xBR_family

Usage

import superxbr from 'super-xbr';
const scaledPixels = superxbr(originalPixels, width, height);

Params

• data: an W*H array of 32-bit integers. The element at position i should be the RGBA pixel at x = i%W, y = i/W.
• width: width of the image in pixels.
• height: height of the image in pixels.

Return value

An array of size 4*W*H representing the enlarged image. The format will be same as the expected input for data.
