基本使用

{
    "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

{
    "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

{
    "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

{
    "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

{
    "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

{
    "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
    }
}

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

{
    "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

{
    "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 和 height 可以设置缩率图显示的高宽

{
    "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。

{
    "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。

{
    "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

{
    "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

{
    "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

{
    "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。

{
    "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

{
    "type": "page",

        "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",
