推荐答案

如果你仔细想想，你是不会知道的图像文件大小它的调整之后。所以，你要么得进行尝试的连续迭代​​事后比较文件的大小，或者你可以改变你的约束图像限制为一组特定的高度和宽度尺寸。

If you think about it, you aren't going to know the filesize of the image until after it's resized. So you've either got to perform a successive iteration of attempts and compare the file sizes afterwards or you could change your constraints to restrict images to a particular set of height and width dimensions.
