scripting - 是否有可用于调整 SVG 大小的脚本？

有没有办法编写将 .SVG 从当前大小(数千像素)重新缩放到更小的大小的脚本？我已经尝试过 ImageMagick，但它对 SVG 渐变的支持太弱以至于无法使用。

目的是解决渲染库中的一个错误，该错误有时会导致具有大像素大小的 svg 分配大光栅(在最终平滑地重新缩放以进行实际显示之前)。

例如，我如何更改这个 1024x1024px svg:

到 102.4x102.4 SVG？如果它也没有丢弃 SVG 的片段，那就太好了(这排除了 libsvgbin2，尽管它很接近)。

最佳答案

你可以替换

<g

与

<g transform="scale(0.5)"

这应该将所有内容缩放 50%。
