只有一张图片时调用onSacle、onRodate，scale和rotate数值会变化但图片不会进行缩放和旋转

 <PhotoProvider
        loop={true}
        onIndexChange={handleIndexChange}
        toolbarRender={({ onScale, scale, rotate, onRotate }) => {
          return (
            <div>
              {/*scale在每次点击后打印的值都会+1直至最大值，但图片不会缩放*/}
              <PlusCircleOutlined onClick={() => { console.log('scale', scale); onScale(scale + 1) }} />
              <MinusCircleOutlined onClick={() => onScale(scale - 1)} />
              <RedoOutlined onClick={() => onRotate(rotate + 90)} />
              <UndoOutlined onClick={() => onRotate(rotate - 90)} />
              <SyncOutlined onClick={() => onRotate(0)} />
              {editable && <DownloadOutlined onClick={download} />}
            </div>
          );
 }}>
...
</PhotoProvider>
