示例1: doneReading
function doneReading() {
if (++filesRead < 2) return;
const diff = new PNG({width: img1.width, height: img1.height});
pixelmatch(img1.data, img2.data, diff.data, img1.width, img1.height, {threshold: 0.1});
diff.pack().pipe(fs.createWriteStream('diff.png'));
}示例2: Promise
return new Promise(function (resolve, reject) {
const png = new PNG();
png.on('parsed', function () {
resolve(png);
});
png.on('error', function (error) {
reject(error);
});
load(image, png);
});示例3: export
