Question

我有一个SVG，代码如下：

<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="150px" height="150px" preserveAspectRatio="xMinYMin meet" viewBox="0 0 150 155" version="1.1" xmlns="http://www.w3.org/2000/svg">
    <g id="g11" transform="matrix(1.25,0,0,-1.25,-100.0791,954.14501)">
        <g id="g3186" transform="translate(6.3490095,-13.703287)">
            <path d="..."></path>
            <path d="..."></path>
            <path d="..."></path>
            <path d="..."></path>
        </g>
    </g>
</svg>

SVG的“原始”尺寸生成的图像是300px×310px。我想整体缩放图像，比方说50％。我已经尝试了各种方法来缩放图像，但我所做的最好的就是将原始图像剪辑或“裁剪”到原始尺寸的50％的区域。

使用preserveAspectRatio，设置视图框，尝试使用transform =“scale（0.5”）等等都没有用。我想做的就是将原始尺寸缩放50％。

Answer 1

transform="scale(0.5)"一定能奏效。你可能做错了什么。

尝试使用g11将g包裹在另一个transform="scale(0.5)"中，然后移除preserveAspectRatio和viewBox

Answer 2

以下是我如何做的一个例子

<!DOCTYPE html>
    <meta charset="utf-8">
    <html>
    <head>
        <script src="http://d3js.org/d3.v3.min.js"></script>
    </head>
    <body>
    <!-- this came from Open Clip Art http://openclipart.org/tags/svg 
         I just took the bits inside the g tag and gave them an id -->
