## 基本使用
```schema
{
"type": "page",
"body": {
"type": "image",
"src": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
}
}
```
也可以配置`name`属性关联上下文数据
```schema
{
"type": "page",
"data": {
"imageUrl": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
"body": {
"type": "image",
"name": "imageUrl"
}
}
```
## 配置标题和说明
```schema
{
"type": "page",
"body": {
"type": "image",
"src": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80",
"title": "这是标题",
"imageCaption": "这是一段说明"
}
}
```
## 配置缩略图
### 显示模式
```schema: scope="body"
{
"type": "form",
"mode": "horizontal",
"data": {
"image": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
"body": [
{
"type": "static-image",
"name": "image",
"label": "宽度占满",
"thumbMode": "w-full"
},
{
"type": "static-image",
"name": "image",
"label": "高度占满",
"thumbMode": "h-full"
},
{
"type": "static-image",
"name": "image",
"label": "颜色",
"label": "默认",
"thumbMode": "contain"
},
{
"type": "static-image",
"name": "image",
"label": "覆盖",
"thumbMode": "cover"
}
]
}
```
### 显示比例
```schema: scope="body"
{
"type": "form",
"mode": "horizontal",
"data": {
"image": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
"body": [
{
"type": "static-image",
"name": "image",
"label": "1比1",
"thumbRatio": "1:1",
"thumbMode": "cover"
},
{
"type": "static-image",
"name": "image",
"label": "4比3",
"thumbRatio": "4:3",
"thumbMode": "cover"
},
{
"type": "static-image",
"name": "image",
"label": "颜色",
"label": "16比9",
"thumbRatio": "16:9",
"thumbMode": "cover"
}
]
}
```
## 放大功能
配置`"enlargeAble": true`,鼠标移动到图片上会显示可点击图标,点击可放大展示
```schema
{
"type": "page",
"body": {
"type": "image",
"src": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80",
"enlargeAble": true
}
}
```
在列表中,图片组件的放大模式下默认展示所有行的图片信息,设置`"enlargeWithGallary": true`效果相同。
```schema
{
"type": "page",
"data": {
"imageList": [
{
"name": "amis",
"image_url": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
{
"name": "amis",
"image_url": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692942/d8e4992057f9.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
{
"name": "tom",
"image_url": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395693148/1314a2a3d3f6.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
{
"name": "jack",
"image_url": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395693379/8f2e79f82be0.jpeg@s_0,w_216,l_1,f_jpg,q_80"
}
]
},
"body": {
"type": "crud",
"source": "${imageList}",
"syncLocation": false,
"columns": [
{
"name": "name",
"label": "名称"
},
{
"type": "image",
"name": "image_url",
"label": "图片",
"enlargeAble": true
}
]
}
}
```
在列表中,图片组件配置`"enlargeWithGallary": false`可以关闭放大模式下图片集列表的展示。
```schema
{
"type": "page",
"data": {
"imageList": [
{
"name": "amis",
"image_url": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
{
"name": "amis",
"image_url": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692942/d8e4992057f9.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
{
"name": "tom",
"image_url": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395693148/1314a2a3d3f6.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
{
"name": "jack",
"image_url": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395693379/8f2e79f82be0.jpeg@s_0,w_216,l_1,f_jpg,q_80"
}
]
},
"body": {
"type": "crud",
"source": "${imageList}",
"syncLocation": false,
"columns": [
{
"name": "name",
"label": "名称"
},
{
"type": "image",
"name": "image_url",
"label": "图片",
"enlargeAble": true,
"enlargeWithGallary": false
}
]
}
}
```
可以配置`originalSrc`,来指定原图资源地址,作为放大预览的图片地址
```schema
{
"type": "page",
"body": {
"type": "image",
"src": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80",
"originalSrc": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg",
"enlargeAble": true
}
}
```
`enlargeTitle`和`enlargeCaption`可以配置放大预览中的标题和描述
```schema
{
"type": "page",
"body": {
"type": "image",
"src": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80",
"originalSrc": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg",
"enlargeAble": true,
"enlargeTitle": "这是一个标题",
"enlargeCaption": "这是一段描述"
}
}
```
## 设置高宽
通过 `width``height` 可以设置缩率图显示的高宽
```schema
{
"type": "page",
"body": {
"type": "image",
"width": "200px",
"height": "200px",
"src": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_400,l_1,f_jpg,q_80"
}
}
```
## 原图模式
> 1.2.3 及以上版本
默认图片为缩略图模式,可以通过配置 imageMode: "original" 修改为原图模式,原图模式为块状展示,宽度尽可能占满。
```schema
{
"type": "page",
"data": {
"imageUrl": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg"
},
"body": {
"type": "image",
"imageMode": "original",
"name": "imageUrl",
"title": "这是标题",
"imageCaption": "这是一段说明"
}
}
```
## 打开外部链接
> 1.3.3 及以上版本
可以设置 href 属性来支持图片点击打开链接,需要注意这和放大功能是冲突的,只能二选一。
```schema: scope="body"
{
"type": "image",
"src": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80",
"href": "https://github.com/baidu/amis"
}
```
href 也可以是模板
```schema
{
"type": "page",
"data": {
"imageUrl": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg",
"imageHref": "https://github.com/baidu/amis"
},
"body": {
"type": "image",
"name": "imageUrl",
"href": "${imageHref}"
}
}
```
## 用作 Field 时
当用在 Table 的列配置 Column、List 的内容、Card 卡片的内容和表单的 Static-XXX 中时,可以设置`name`属性,映射同名变量
### Table 中的列类型
```schema: scope="body"
{
"type": "table",
"data": {
"items": [
{
"id": "1",
"image": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
{
"id": "2",
"image": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
{
"id": "3",
"image": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
}
]
},
"columns": [
{
"name": "id",
"label": "Id"
},
{
"name": "image",
"label": "图片",
"type": "image"
}
]
}
```
List 的内容、Card 卡片的内容配置同上
### Form 中静态展示
```schema: scope="body"
{
"type": "form",
"data": {
"image": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80"
},
"body": [
{
"type": "static-image",
"name": "image",
"label": "颜色",
"innerClassName": "no-border"
}
]
}
```
## 自定义点击行为
> 1.5.0 及以上版本
可以通过 `clickAction` 设置点击触发行为。
```schema: scope="body"
{
"type": "image",
"src": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80",
"class": "cursor-pointer",
"clickAction": {
"actionType": "dialog",
"dialog": {
"title": "弹框标题",
"body": "这是一个弹框"
}
}
}
```
## 工具栏
> 2.2.0 及以上版本
配置`"showToolbar": true`使图片在放大模式下开启图片工具栏。配置`"toolbarActions"`属性可以自定义工具栏的展示方式,具体配置参考[ImageAction](./image#imageaction)
```schema
{
"type": "page",
"body": {
"type": "image",
"src": "https://internal-amis-res.cdn.bcebos.com/images/2020-1/1578395692722/4f3cb4202335.jpeg@s_0,w_216,l_1,f_jpg,q_80",
"enlargeAble": true,
"showToolbar": true
}
}
```
