## 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` 和 `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
    }
}
```

```

## 事件表

当前组件会对外派发以下事件，可以通过`onEvent`来监听这些事件，并通过`actions`来配置执行的动作，在`actions`中可以通过`${事件参数名}`或`${event.data.[事件参数名]}`来获取事件产生的数据，详细查看[事件动作](../../docs/concepts/event-action)。

| 事件名称   | 事件参数   | 说明           |
| ---------- | ---------- | -------------- |
| click      | 上下文数据 | 点击图片时触发 |
| mouseenter | 上下文数据 | 鼠标移入时触发 |
| mouseleave | 上下文数据 | 鼠标移入时触发 |

### click / mouseenter / mouseleave

点击图片 / 鼠标移入图片 / 鼠标移出图片，可以尝试通过${event.context.nativeEvent}获取鼠标事件对象。

```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",
    "onEvent": {
        "click": {
            "actions": [
                {
                    "actionType": "toast",
                    "args": {
                        "msg": "图片被点击了"
                    }
                }
            ]
        },
        "mouseenter": {
            "actions": [
                {
                    "actionType": "toast",
                    "args": {
                        "msg": "鼠标移入图片"
                    }
                }
            ]
        },
        "mouseleave": {
            "actions": [
                {
                    "actionType": "toast",
                    "args": {
                        "msg": "鼠标移出图片"
                    }
                }
            ]
        }
    }
}
```

## 动作表

当前组件对外暴露以下特性动作，其他组件可以通过指定`actionType: 动作名称`、`componentId: 该组件id`来触发这些动作，动作配置可以通过`args: {动作配置项名称: xxx}`来配置具体的参数，详细请查看[事件动作](../../docs/concepts/event-action#触发其他组件的动作)。

| 动作名称 | 动作配置                                                                                                                              | 说明                                 |
| -------- | ------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------ |
| preview  | -                                                                                                                                     | 预览图片                             |
| zoom     | `scale: number` 或 `scale: `[模板](../../docs/concepts/template)，定义每次放大或缩小图片的百分比大小，正值为放大，负值为缩小，默认 50 | 调整图片比例，将图片等比例放大或缩小 |

### preview

预览图片，可以通过配置`originalSrc`来指定预览的原图地址。

```schema: scope="body"
{
    "type": "page",
    "body": {
        "type": "container",
        "body": [
            {
                "type": "container",
                "body": [
                    {
                        "type": "image",
                        "className": "mb-1",
                        "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",
                        "id": "previewImage"
                    }
                ]
            },
            {
                "type": "action",
                "label": "预览图片",
                "onEvent": {
                    "click": {
                        "actions": [
                            {
                                "actionType": "preview",
                                "componentId": "previewImage"
                            }
                        ]
                    }
                }
            }
        ]
    }
}
```

### zoom

调整图片比例，将图片等比例放大或缩小。可以通过配置图片的`maxScale`和`minScale`来限制调整的比例。

```schema: scope="body"
{
    "type": "page",
    "body": {
        "type": "container",
        "body": [
            {
                "type": "flex",
                "items": [
                    {
                        "type": "image",
                        "innerClassName": "no-border",
                        "className": "mt-5 mb-5",

                                "args": {
                                    "scale": 50,
                                },
                                "componentId": "zoomImage"
                            }
                        ]
                    }
                }
            },
            {

                                "args": {
                                    "scale": -50,
                                },
                                "componentId": "zoomImage"
                            }
                        ]
