【中文标题】大尺寸的 svg 无法正常工作 如何在 react-pan-zoom-svg 中设置大尺寸的 svg？【英文标题】：big size of svg not working proper how to set big svg in react-pan-zoon-svg? 【发布时间】：2018-10-08 02:25:22 【问题描述】：我在这里使用 react-pan-zoom-svg 并尝试在可缩放区域加载大型 SVG
我遇到了一些问题
1) 当svg 加载时，它不会从 svg 的中心点加载
2) 当我移动SVG 时，它的矩阵值取负数
3) 适合屏幕不工作
共享的 jspaddel 无法正常工作，但我无法解决它，但我的所有代码都在那里
请帮忙
提前谢谢你

【参考方案1】：不确定您要达到什么目标以及如何决定这些“固定宽度和高度”。
但这是您的代码的工作版本： https://jsfiddle.net/tzookb/79742ncq/
现在请定义您想要实现的目标，以便我提供帮助。
我用 react 和 svg 斗争了很长时间。
快速更新您的代码：
const width = window.innerWidth - 20;
const height= window.innerHeight - 20;
return (
<ReactSVGPanZoom
width=width height=height scaleFactorMin=0.99
onClick=event => console.log(event.x, event.y, event.originalEvent)>
【讨论】：
【参考方案2】：我花了一些时间来处理这个问题，我可以实现一些所需的功能。
工作演示： https://codesandbox.io/s/wnp0np9l18
1) 当 svg 加载时，它不会从 svg 的中心点加载
我所做的是一种解决方法，给定您可以设置“缩放”位置的值，值为e 和f。我无法研究更多的含义，但这是一个开始。我只是给ReactSVGPanZoom 组件基于SVG 的值。
<ReactSVGPanZoom
value=
e: SVG_X_Size / 2,
f: SVG_Y_Size / 2
...rest of values
...
2) 当我移动 SVG 时，它的矩阵值为负数
-
不知道这个。
3) 适合屏幕不工作
-
规模工厂不够规模，将其设置为：
scaleFactorMin=0.0001 应该修复它。
【讨论】：
【参考方案3】：无论如何，我对你的问题有点困惑，我正在尝试用我对你问题的理解来解决你的问题。
要解决您的问题，您需要更改您的 ReactSVGPanZoom
你的代码应该是
const ReactSVGPanZoom = window.ReactSVGPanZoom;
class Example extends React.Component
render ()
const width = window.innerWidth - 20;
const height= window.innerHeight - 20;
return (
<ReactSVGPanZoom
width=width height=height scaleFactorMin=0.99
onClick=event => console.log(event.x, event.y, event.originalEvent)>
<svg width=4970 height=6480>
