How to convert an HTML element or document into image ?
In this article, I will be able to show you ways to convert Html div to a picture using JQuery. Here, I'm generating an HTML div element on the client-side to image png using the html2canvas.js library.
HTML5 has some excellent features; you'll draw charts using canvas tag later you'll reserve it as image png or JPEG format.
To begin, download the latest jQuery library and import it into the online page, we'd like another js library Html2canvas.js, for both I referred cdn, when the user clicks the convert to image button, the div element gets an image printed on canvas then downloaded to the local drive as picture using client-side jQuery.
Below are the example to convert div or Html section into image:-
<!DOCTYPE html>
<html>
<head>
