# Icons and SVG Illustrations[](#icons-and-svg-illustrations "Permalink")
我们在[`gitlab-svgs`](https://gitlab.com/gitlab-org/gitlab-svgs)存储库中管理自己的图标和插图库. 该存储库在[npm](https://s0www0npmjs0com.icopy.site/package/@gitlab/svgs)上发布,并通过 yarn 作为依赖项进行管理. 您可以[在此处](https://gitlab-org.gitlab.io/gitlab-svgs)浏览所有可用的图标和插图. 要升级到新版本,请运行`yarn upgrade @gitlab/svgs` .
## Icons[](#icons "Permalink")
我们正在 GitLab 中使用 SVG Sprite 使用 SVG 图标. 这意味着图标仅加载一次,并通过 ID 进行引用. 子画面 SVG 位于`/assets/icons.svg`下.
我们的目标是一一替换所有内联 SVG 图标(如目前已膨胀的 HTML)以及所有 Font Awesome 图标.
### Usage in HAML/Rails[](#usage-in-hamlrails "Permalink")
要在 HAML 或 Rails 中使用精灵图标,我们使用特定的辅助函数:
```
sprite_icon(icon_name, size: nil, css_class: '')
```
* **icon_name**使用可以在 SVG Sprite 中找到的 icon_name( [此处提供概述](https://gitlab-org.gitlab.io/gitlab-svgs) ).
* **size(可选)**使用以下大小之一: `s16` (将被翻译成`s16`类)
* **css_class(可选)**如果要添加其他 CSS 类
**Example**
```
= sprite_icon('issues', size: 72, css_class: 'icon-danger')
```
**上面示例的输出**
```
<svg class="s72 icon-danger">
<use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="/assets/icons.svg#issues"></use>
</svg>
```
### Usage in Vue[](#usage-in-vue "Permalink")
我们的组件库[GitLab UI](https://gitlab-org.gitlab.io/gitlab-ui/)提供了一个用于显示精灵图标的组件.
样品用法:
```
<script>
import { GlIcon } from "@gitlab/ui";
export default {
components: {
GlIcon,
},
};
<script>
<template>
<gl-icon
name="issues"
:size="24"
class="class-name"
/>
</template>
```
* **name** SVG Sprite 中图标的名称( [此处提供概述](https://gitlab-org.gitlab.io/gitlab-svgs) ).
* **size(可选)** ,然后将大小的数字值映射到特定的 CSS 类(可用大小: `sXX`映射到`sXX` CSS 类)
* **class(可选)**要添加到 SVG 标签的其他 CSS 类.
### Usage in HTML/JS[](#usage-in-htmljs "Permalink")
请在 JS 中使用以下函数来呈现图标: `gl.utils.spriteIcon(iconName)`
## SVG Illustrations[](#svg-illustrations "Permalink")
从现在开始,对于任何基于 SVG 的插图,请使用简单的`img`标签来显示插图,只需使用`image_tag`或`image_path`帮助器即可. 请使用周围的`svg-content`类,以确保呈现效果良好.
### Usage in HAML/Rails[](#usage-in-hamlrails-1 "Permalink")
**Example**
```
.svg-content
= image_tag 'illustrations/merge_requests.svg'
```
### Usage in Vue[](#usage-in-vue-1 "Permalink")
要在模板中使用 SVG 插图,请将路径作为属性提供,并通过标准`img`标签显示它.
Component:
```
<script>
export default {
props: {
svgIllustrationPath: {
type: String,
required: true,
},
},
};
<script>
<template>
<img :src="svgIllustrationPath" />
</template>
