问题描述
我在业余时间是一名艺术摄影师，我正在使用一个很棒的开源幻灯片库为我的网站（注：NSFW）设计一个新的设计， JSSOR 。
I'm an art photographer in my spare time, and I'm working on a new design for my web site (note: NSFW) using a great open-source slideshow library, JSSOR.
我想填写浏览器而不改变宽高比照片（即，尽可能使它们居中）。
I want to fill the browser without changing the aspect ratio of the photos (i.e., center them as large as possible).
A $ FillMode 1 为此工作得很漂亮，但我在创建代码以响应浏览器调整大小/旋转方面遇到了麻烦。
A $FillMode of 1 works beautifully for this, but I'm having trouble creating code to respond to browser resize/rotation.
在调整大小时计算适当的新高度/宽度（浏览器减去页脚文本和一点边距）很容易，但是在幻灯片初始化后似乎无法以编程方式设置宽度和高度。我错过了什么吗？
Calculating the proper new height/width (browser minus footer text and a little margin) on resize is easy, but there appears to be no way to set the width and height programmatically after the slideshow has initialized. Am I missing something?
我见过的所有JSSOR响应代码（例如，这个答案）使用 $ ScaleWidth（）方法。不幸的是，该方法试图维护幻灯片画布的宽高比，而我希望幻灯片画布与浏览器一起拉伸（同时保持 $ FillMode = 1 逻辑）。
All of the responsive code I've seen for JSSOR (e.g., this answer) uses the $ScaleWidth() method. Unfortunately, that method attempts to maintain the aspect ratio of the slideshow canvas, while I want the slideshow canvas to stretch with the browser (while maintaining the aspect ration of the photo via the $FillMode=1 logic).
我挖到 $ ScaleWidth的代码（ ），但那里有一些奇怪的DOM-voodoo，所以我还没想出如何创建一个我自己的方法来强制调整大小到特定的宽度和高度。
想法？
