我如何从StorageItemThumbnail对象实际使用此缓冲区？ [英] how do i actually USE this buffer from StorageItemThumbnail object ?

问题描述

代码是

Windows.Storage.StorageFile.getFileFromPathAsync('C:\\Users\\Raymond Goldman\\Pictures\\Korean Artist\\photo.jpg').done(function (file) {
file.getThumbnailAsync(Windows.Storage.FileProperties.ThumbnailMode.picturesView, 100, Windows.Storage.FileProperties.ThumbnailOptions.resizeThumbnail).then(function (file_thumbnail) {
                        var file_thumbnail = file_thumbnail;
			//LOL, what is the next step ?
                    });
                });

如何使用此缩略图对象，其中大多数方法返回缓冲区，如何将其实际显示到视频标记中，或者更好的是，只需从该缩略图中取出一张图片进入html？

How do I use this thumbnail object, most of it's methods returns buffers, how do I actually shows it into video tag, or better yet, just take one picture from that thumbnail into the html ?
