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JSSOR为我的网站（注：NSFW）开发新设计。
我想在不改变照片宽高比的情况下填充浏览器（即，尽可能将它们居中）。
$FillMode的{{1}}可以很好地为此工作，但我无法创建代码来响应浏览器调整大小/轮播。
在调整大小时计算适当的新高度/宽度（浏览器减去页脚文本和一点边距）很容易，但是在幻灯片显示后，似乎无法以编程方式设置宽度和高度初始化。我错过了什么吗？
我在JSSOR（例如，this answer）中看到的所有响应代码都使用1方法。不幸的是，该方法试图维护幻灯片画布的宽高比，而我希望幻灯片画布与浏览器一起拉伸（同时保持$ScaleWidth()逻辑）。
我为$FillMode=1挖了the code，但那里有一些奇怪的DOM-voodoo，所以我还没弄明白如何创建一个我自己的强制方法-resize到特定宽度和高度。
想法？

对于任何寻找$ ResizeCanvas的人。他们最终添加了一个函数，可以帮助用$ ScaleSize获得所需的滑块大小。
对于最新版本25.2.0，我们添加了一个新方法$ ScaleSize（width， 高度）而不是$ ResizeCanvas。
