问题描述
我正在使用 Swiffy 渲染到隐藏的画布上，以便我可以获取结果并在其他地方使用它.我遇到的问题是，当我为 Swiffy 调整容器 div 的大小时，它不会使实际画布比可用视口大小更大.如果我将 Swiffy div 的尺寸设置为大于视口，那么画布只会变得与视口一样大 - 它不想将画布的任何部分放在屏幕外.
I'm using Swiffy to render onto a hidden canvas so that I can take the result and use it elsewhere. The problem I'm running into is that when I resize the container div for Swiffy it won't make the actual canvas any bigger than the available viewport size. If I set the dimensions of the Swiffy div larger than the viewport then the canvas will only get as big as the viewport - it doesn't want to put any part of the canvas offscreen.
我确定这是为了提高效率，如果它正常在屏幕外，则没有理由渲染某些内容，但我需要让 Swiffy 始终以我想要的任何大小渲染它.
I'm sure this is for efficiency, there's no reason to render something if it's offscreen normally, but I need to have Swiffy render it all the time, at whatever size I want.
此外，如果 Swiffy 容器 div 没有附加到 DOM，Swiffy 只是简单地拒绝做任何事情.(强制画布的宽度和高度为 0).
Additionally, Swiffy just plain refuses to do anything if the Swiffy container div isn't attached to the DOM. (Forces the canvas to have a width and height of 0).
有没有办法解决这个问题，而不必深入研究(混淆的)Swiffy 客户端运行时并修改它?如何欺骗 Swiffy 使其渲染得大于视口大小?
Is there a way around this without having to dig into the (obfuscated) Swiffy client runtime and modify it? How can I trick Swiffy into rendering larger than the viewport size?
我实际上能够通过将 window.innerWidth 更改为我想要的任何内容来欺骗 swiffy 呈现比视口更大的渲染.不过，这是一个非常丑陋的 hack，我不想覆盖它，因为它会导致很多问题.
I was actually able to trick swiffy into rendering larger than the viewport by changing window.innerWidth to whatever I want. That's a really ugly hack though and I hate to overwrite that as it causes a lot of issues.
推荐答案
如果你的 swiffy 运行时版本是 7.3，你可以直接 hack js.
If your swiffy runtime version is 7.3, you can hack the js directly.
只需删除或注释b.xj(c);"在 g.Tp() 函数中.我不在乎屏幕外渲染的任何优势.至少，现在可以用了.
Just remove or comment "b.xj(c);" in g.Tp() function. I don't care any advantage of offscreen rendering. At least, it works now.
我认为这是一个严重的错误.
I think it's a serious bug.
请注意，它在 iframe 中很好，无需 hack.
Note that it's good in iframe, no need to hack.
