有没有办法将.SVG的重新缩放从其当前大小（数千像素）重新缩放到更小的尺寸？我已经尝试过ImageMagick，但它对SVG渐变的支持太弱而无法使用。
目的是解决渲染库中的错误，该错误有时会导致具有较大像素大小的svgs分配大型栅格（在最终平滑地重新缩放以进行实际显示之前）。
例如，如何更改此1024x1024px svg：

到102.4x102.4 SVG？如果它没有丢弃SVG的部分也是很好的（尽管它接近了libsvgbin2的哪种规则）。
答案 0 :(得分：6)
你可以替换
<g
带
<g transform="scale(0.5)"
哪个应该将所有内容扩展50％。
答案 1 :(得分：1)
我会使用Apache Batik Toolkit编写一个小的Java App，它通过你的SVG文档树运行并转换所有元素。
答案 2 :(得分：0)
viewBox属性，可以进行缩放技巧，也可以说是缩放整个svg画布。例如
<svg
xmlns="http://www.w3.org/2000/svg"
width="1024.09"
height="1024.36"
id="svg2"
viewBox = "0 0 300 300">
这里是viewBox，0,0分别用于新的x和y，300,300用于新宽度和画布的新高度。
答案 3 :(得分：0)
只需使用文本编辑器调整width标记的height和svg属性：
<svg
...
width="102.409"
height="102.436"
...
