# How to Export HTML to Image in Angular Component

As a web developer, you may encounter scenarios where you need to export the content of an HTML element to an image. In this tutorial, we will explore how to achieve this using the `html2canvas` library in an Angular component.

## Step 1: Install the html2canvas Package

Firstly, install the `html2canvas` package using npm:

```bash

npm install html2canvas --save

```

## Step 2: Import Required Modules

In your Angular component file, import the necessary modules:

import { Component, OnInit, OnDestroy, ElementRef, ViewChild } from

"@angular/core";

import html2canvas from 'html2canvas';

## Step 3: Component Setup

Define the necessary elements in your component:

@ViewChild('screen') screen: ElementRef;

@ViewChild('canvas') canvas: ElementRef;

@ViewChild('downloadLink') downloadLink: ElementRef;

## Step 4: Implement Image Download Function

Add a function to download the HTML content as an image:

downloadImage(){

html2canvas(this.screen.nativeElement).then(canvas => {

this.canvas.nativeElement.src = canvas.toDataURL();

this.downloadLink.nativeElement.href = canvas.toDataURL('image/png');

this.downloadLink.nativeElement.download = 'full_page.png';

this.downloadLink.nativeElement.click();

});

}

## Step 5: HTML Setup

In your component's HTML file, set up the elements for exporting:

<div #screen>

<h1>Hello Test</h1>

</div>

<div id="download">

<img #canvas>

<a #downloadLink></a>

</div>

## Step 6: Invoking the Function

Call the `downloadImage` function from your component when you want to trigger the export.

Now you have a complete setup to export HTML content as an image in your Angular component using `html2canvas`. Feel free to customize the code according to your specific requirements.

Happy coding!
