一 、svg图像是什么
SVG（可缩放矢量图形）是一种图像格式，它以XML文档的形式存在，用以描述图像中的形状、线条、文本和颜色等元素。由于其基于矢量的特性，SVG图像在放大或改变尺寸时能够保持图形质量不受影响。这种格式特别适合用于需要高清显示和可编辑性的网络图形设计。接下来从以下几方面进行深入了解：
- SVG图像的基本特性
- 可缩放性：SVG图像的最大特点是其可无限缩放而不会失真。这是因为它们基于矢量而不是像素，这使得SVG尤其适合需要在不同分辨率和尺寸下保持清晰可见的应用场景。
- XML基础：SVG使用XML来编码图像，这意味着它们是可由文本编辑器创建和编辑的，并且可以与JavaScript等Web技术无缝集成，为开发者提供了高度的灵活性和控制力。
- SVG图像的技术细节
- 图像构成：SVG文件通过一系列的矢量指令来定义图形，这些指令包括路径、圆、矩形等基本形状，以及如何填充和描边这些形状的颜色和样式。
- 交互和动画：由于SVG是基于DOM的，它们可以与HTML、CSS和JavaScript结合使用，实现交互式功能和动画效果，这在现代Web设计中尤为重要。
- SVG与其他格式的比较
- 与位图格式的对比：与JPEG和PNG这类基于像素的位图格式相比，SVG提供了更高的灵活性和更小的文件大小，尤其是对于简单的图形设计。
- 历史和优势：SVG自2003年成为W3C推荐标准以来，因其开放性和兼容性强，逐渐取代了如Flash这样的专有格式，成为了Web图形的标准选择之一。
- SVG的应用场景
- 网页设计：SVG广泛用于现代网页设计中，特别是在创建响应式设计时，因为它们能够适应各种屏幕尺寸而不失清晰度。
- 高质量打印：由于SVG的高质量输出，它们也适用于需要在多种尺寸上保持高质量的打印设计工作。
- 创建和编辑SVG图像
- 工具和软件：虽然SVG可以用任何文本编辑器创建，但市面上也有许多专门的图形软件支持SVG的创建和编辑，如Adobe Illustrator和Inkscape。
- 学习资源：网络上有许多教程和参考手册可供学习SVG的基础知识和应用，使得设计师和开发者可以快速上手SVG图像的创建和优化。
二、图片转svg
在开发过程中，可以考虑先生成图片（png或者jpg等格式）然后再将其转换为svg，这里推荐个我最近使用的转换网站，对于新用户有免费的转换点可以转换至少10次，当然有更好的网站可以分享到评论区

三、在vue中引入
定义文件logo.vue，并在其中将svg文件对应的xml代码复制进template中，其中可以使用transform参数对svg图像做变换，这里做的变换就是缩小为原来大小的0.4倍（注意原始svg是黑白的，需要手动fill添加颜色！！）
<template>
