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).

### Loading Online Images
The default network timeout period is 5 minutes for loading online images. When using an online image, you are advised to use **alt** to configure the placeholder image displayed during loading. If more flexible network configuration is required, use the [HTTP](../../connectivity/http-request.md) module in the SDK to send a network request, and then decode the returned data into a `PixelMap` in the **\<Image>** component. For details about image development, see [Image Development](../../media/image.md). The code snippet is as follows:
```tsx
// @ts-nocheck
import http from '@ohos.net.http';
import ResponseCode from '@ohos.net.http';
import image from '@ohos.multimedia.image'
@Entry
@Component
struct Index {
// Create a PixelMap state variable to receive online images.

.onClick(() => {
this.httpRequest();
})
Image(this.image).height(100).width(100)
}
.width('100%')
.height('100%')
.padding(10)
}
// Request an online image.
private httpRequest() {
let httpRequest = http.createHttp();
httpRequest.request(
"https://www.example.com/xxx.png", // Enter a specific URL of the online image.
(error, data) => {
if(error) {
console.log("error code: " + error.code + ", msg: " + error.message)
} else {
let code = data.responseCode
if(ResponseCode.ResponseCode.OK == code) {
let imageSource = image.createImageSource(data.result)
let options = {alphaType: 0, // Transparency
editable: false, // Whether the image is editable
pixelFormat: 3, // Pixel format
scaleMode: 1, // Scale mode
size: {height: 100, width: 100}} // Image size
imageSource.createPixelMap(options).then((pixelMap) => {
this.image = pixelMap
})
} else {
console.log("response code: " + code);
}
}
}
)
}
}
```
**NOTE**<br>For details about the request mode, timeout, and additional request parameters for loading online images, see [`request()`](../../reference/apis/js-apis-http.md) in the HTTP module.

| 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. |

The **\<GridCol>** component must be used as a child component of the [GridRow](ts-container-gridrow.md) container.
> **NOTE**
>
> This component is supported since API version 9. Updates will be marked with a superscript to indicate their earliest API version.
## Child Components
This component can contain only one child component.
## APIs
GridCol(option?:{span?: number | GridColColumnOption, offset?: number | GridColColumnOption, order?: number | GridColColumnOption})
**Parameters**
| Name| Type | Mandatory| Description |
| ------ | ----------------------------- | ---- | ------------------------------------------------------------ |
| span | number \| GridColColumnOption | No | Number of occupied columns. If it is set to **0**, the element is not involved in layout calculation, that is, the element is not rendered.<br>Default value: **1**|
| offset | number \| GridColColumnOption | No | Number of offset columns relative to the previous child component of the grid<br>Default value: **0** |
| order | number \| GridColColumnOption | No | Sequence number of the element. Child components of the grid are sorted in ascending order based on their sequence numbers.<br>Default value: **0**|
## Attributes
| Name| Type | Mandatory| Description |
| ------ | ----------------------------- | ---- | ------------------------------------------------------------ |
| span | number \| GridColColumnOption | No | Number of occupied columns. If it is set to **0**, the element is not involved in layout calculation, that is, the element is not rendered.<br>Default value: **1**|
| offset | number \| GridColColumnOption | No | Number of offset columns relative to the previous child component of the grid<br>Default value: **0** |
| order | number \| GridColColumnOption | No | Sequence number of the element. Child components of the grid are sorted in ascending order based on their sequence numbers.<br>Default value: **0**|
## GridColColumnOption
| Name | Type | Mandatory | Description |
| ----- | ------ | ---- | ---------------------------------------- |
| xs | number | No | Device of the minimum size. |
| sm | number | No | Small-sized device. |
| md | number | No | Medium-sized device. |
| lg | number | No | Large-sized device. |
| xl | number | No | Extra-large-sized device. |
| xxl | number | No | Ultra-large-sized device. |
The values of `span`, `offset`, and `order` attributes are inherited in the sequence of `xs`, `sm`, `md`, `lg`, `xl`, and `xxl`. If no value is set for a breakpoint, the value is obtained from the previous breakpoint.
|Parameter\Breakpoint|xs|sm|md|lg|xl|xxl|
|---|---|---|---|---|---|---|
|span |2 |2 |3 |3 |4 |4 |
|offset |2 |2 |3 |5 |5 |5 |
|order |20 |20 |20 |3 |3 |3 |
