示例1: sharp

        // output.jpg is a 300 pixels wide and 200 pixels high image
        // containing a scaled and cropped version of input.jpg
    });

let transformer = sharp()
    .resize(300)
    .on('info', (info: sharp.OutputInfo) => {
        console.log('Image height is ' + info.height);
    });
readableStream.pipe(transformer).pipe(writableStream);

console.log(sharp.format);
console.log(sharp.versions);

sharp.queue.on('change', (queueLength: number) => {
    console.log('Queue contains ' + queueLength + ' task(s)');
});

let pipeline: sharp.SharpInstance = sharp().rotate();
pipeline.clone().resize(800, 600).pipe(writableStream);
pipeline.clone().extract({ left: 20, top: 20, width: 100, height: 100 }).pipe(writableStream);
readableStream.pipe(pipeline);
// firstWritableStream receives auto-rotated, resized readableStream
// secondWritableStream receives auto-rotated, extracted region of readableStream

const image: sharp.SharpInstance = sharp(input);
image
    .metadata()
    .then<Buffer|undefined>((metadata: sharp.Metadata) => {
        if (metadata.width) {
            return image
