A type-safe, modular, chainable image processing library built on top of OpenCV.js with a fluent API leveraging pipeline processing.

import{cv,registry}from"../index";function defaultOptions(){return{}}export function grayscale(img,options){let imgGrayscale=new cv.Mat;cv.cvtColor(img,imgGrayscale,cv.COLOR_RGBA2GRAY);img.delete();return{img:imgGrayscale,width:imgGrayscale.cols,height:imgGrayscale.rows}}registry.register("grayscale",grayscale,defaultOptions);
