You can call the APIs provided by the **Camera** module to develop a distributed camera that provides the basic camera functions such as shooting and video recording.
## How to Develop
Connect your calculator to a distributed device. Your calculator will call **getCameras()** to obtain the camera list and traverse the returned camera list to check **ConnctionType** of the **Camera** objects. If **ConnctionType** of a **Camera** object is **CAMERA_CONNECTION_REMOTE**, your calculator will use this object to create a **CameraInput** object. The subsequent call process is the same as that of the local camera development. For details about the local camera development, see [Camera Development](./camera.md).

### PanGestureOptions
## PanGestureOptions
The attributes of the pan gesture recognizer can be dynamically modified using the **PanGestureOptions** API. This avoids modifying attributes through state variables, which will cause the UI to be refreshed.
PanGestureOptions(options?: { fingers?: number, direction?: PanDirection, distance?: number })
PanGestureOptions(value?: { fingers?: number; direction?: PanDirection; distance?: number })

| angle | number | Angle of the swipe gesture.<br/>**NOTE**<br/>Angle calculation method: After a swipe gesture is recognized, a line connecting the two fingers is identified as the initial line. As the fingers swipe, the line between the fingers rotates. Based on the coordinates of the initial line's and current line's end points, an arc tangent function is used to calculate the respective included angle of the points relative to the horizontal direction. Rotation angle = arctan2(cy2-cy1,cx2-cx1) - arctan2(y2-y1,x2-x1). The initial line is used as the coordinate system. The clockwise rotation is 0 to 180 degrees, and the counter-clockwise rotation is –180 to 0 degrees. |
| speed | number | Speed of the swipe gesture. |

## Notes About auto-fill
In the **columnsTemplate** and **rowsTemplate** attributes of the **\<Grid>** component, **auto-fill** supports only the following formats:
```css
repeat(auto-fill, track-size)
```
The keywords **repeat** and **auto-fill** are used. **track-size** indicates the row height or column width, which can be in the unit of px, vp, %, or valid digits. The value must contain at least one valid row height or column width.
## ItemDragInfo
| Name | Type | Description |
| ---------- | ---------- | ---------- |
| x | number | X-coordinate of the dragged item. |
| y | number | Y-coordinate of the dragged item. |

A grid supports a maximum of six breakpoints: xs, sm, md, lg, xl and xxl, whose names cannot be changed. Assume that the input array is [n0, n1, n2, n3, n4], then the value ranges of breakpoints are as follows.
|Breakpoint|Value Range|
|---|-----------|
|xs |[0, n0) |
|sm |[n0, n1) |
|md |[n1, n2) |
|lg |[n2, n3) |
|xl |[n3, n4) |
|xxl|[n4, INF) |
**NOTE**
* Grid elements can be arranged only in the **Row** or **RowReverse** direction, but not in the **Column** or **ColumnReverse** direction.
* The location and size of a grid child component can be calculated only based on **span** and **offset**. If the **span** values of child components add up to a number greater than the allowed number of columns, the grid will automatically wraps lines.
* If the **span** value of a single child component exceeds the maximum number of columns, the maximum number of columns is used.
* If a child component takes up more than the total number of columns according to its **offset** and **span** settings, it will be placed in a new row.
* Below is the display effect of **Item1: GridCol({span: 6}), Item2: GridCol({ span: 8, offset:11})**.

# ListItemGroup
The **\<ListItemGroup>** component is used to display list item groups. It must be used with the **[\<List>](ts-container-list.md)** and, if not otherwise specified, takes up the entire width of the **\<List>** component.
> **NOTE**
>
> This component is supported since API version 9. Updates will be marked with a superscript to indicate their earliest API version.
## Usage Guidelines
If the **listDirection** attribute of the parent **\<List>** component is set to **Axis.Vertical**, the **height** attribute of the **\<ListItemGroup>** component cannot be set. The height of a **\<ListItemGroup>** component is the sum of its header height, footer height, and total height of the list items. If the **listDirection** attribute of the parent **\<List>** component is set to **Axis.Horizontal**, the **width** attribute of the **\<ListItemGroup>** component cannot be set. The width of a **\<ListItemGroup>** component is the sum of its header width, footer width, and total width of the list items.
Currently, the list items in the **\<ListItemGroup>** component cannot be edited, selected, or dragged. That is, the **editable** and **selectable** attributes of these list items do not take effect.
## Child Components
This component supports the **[\<ListItem>](ts-container-listitem.md)** child component.
## APIs
ListItemGroup(options?: {header?: CustomBuilder, footer?: CustomBuilder, space?: number | string})
**Parameters**
| Name| Type| Mandatory| Description|
| -------- | -------- | -------- | -------- |
| header | [CustomBuilder](ts-types.md#custombuilder8) | No| Header of the **\<ListItemGroup>** component.|
| footer | [CustomBuilder](ts-types.md#custombuilder8) | No| Footer of the **\<ListItemGroup>** component.|
| space | number \| string | No| Spacing between list items. This parameter is valid only between list items, but not between a header and list item or between a footer and list item.|
## Attributes
| Name| Type| Description|
| -------- | -------- | -------- |
| divider | {<br>strokeWidth: [Length](ts-types.md#length),<br>color?: [ResourceColor](ts-types.md#resourcecolor),<br>startMargin?: [Length](ts-types.md#length),<br>endMargin?: [Length](ts-types.md#length)<br>} \| null | Style of the divider for the list items. By default, there is no divider.<br>- **strokeWidth**: stroke width of the divider.<br>- **color**: color of the divider.<br>**startMargin**: distance between the divider and the start of the list.<br>**endMargin**: distance between the divider and the end of the list.|
