Imagemagick-修剪SVG画布以适合

Question

我收集了一些SVG，这些画布似乎没有适合其大小的画布。因此，它们似乎偏离中心。我可以将它们导入到Sketch中，然后再次将它们导出为SVG。 Sketch将采用SVG并修剪画布，因此SVG的填充值非常小。它确实完成了我想要的（劳动密集型），但是，我想确定如何以编程方式执行此操作。

我正在使用此仓库中的SVG：https://github.com/erikflowers/weather-icons

我执行的命令：mogrify -density 3600 -extent 1100x1100 -gravity center -background none -format png *.svg

这里是转换SVG之后的示例PNG，带有mogrify：

这里是通过Sketch导出然后转换的示例PNG。

Answer 1

我认为您已经关闭，但是在扩展画布之前需要执行修剪操作。实际上，-gravity center -extent 1100x1100应该是最后一个操作。

mogrify -density 3600 -background none -fill white \
        -trim -gravity center -extent 1100x1100 \
        -format png wi-thunderstorm.svg

尽管将-density与-size交换可能与Sketch更一致。

 mogrify -size 1100x1100 -background none -fill white \
         -trim -gravity Center -extent 1100x1100 \
         -format png wi-thunderstorm.svg 

Answer 2

此命令将获取当前目录中的所有SVG文件，将它们修剪到其寿命的一毫米以内，然后在所有侧面添加10px透明边框：

import 'bootstrap';

Answer 3

只要您想在代码中更新实际的SVG，就可以按照以下方法进行操作。

这是Java语言。因此，您可以编写类似无头的Chrome脚本的内容。或者例如，您可以将其转换为Java并使用Batik。

var svg = document.getElementById("recenter");

// Get the real bounding box of the icon shape
var bbox = svg.getBBox();

// Get the viewBox width and height
var viewBox_width = svg.viewBox.baseVal.width;
var viewBox_height = svg.viewBox.baseVal.height;

// Recenter the contents
svg.viewBox.baseVal.x = bbox.x - (viewBox_width - bbox.width) / 2;
svg.viewBox.baseVal.y = bbox.y - (viewBox_height - bbox.height) / 2;

svg {
  width: 200px;
  background: linen;
}
