Creating image using html5
I wanted to know if it is possible to create an image us开发者_高级运维ing html5. Currently i am creating a text using canvas, now i want to convert that text into an image.
In order to save the canvas to an image file, you can use Nihilogic's code.
Use the canvas text functions.
For example:
<html>
<head>
<title>Canvas tutorial</title>
<script type="text/javascript">
function draw(){
var canvas = document.getElementById('tutorial');
if (canvas.getContext){
var ctx = canvas.getContext('2d');
ctx.fillText("Sample String", 10, 50);
}
}
</script>
<style type="text/css">
canvas { border: 1px solid black; }
</style>
</head>
<body onload="draw();">
<canvas id="tutorial" width="150" height="150"></canvas>
</body>
</html>
Create an image DOM element, and set the src to the canvas.toDataURL method.
var c = document.getElementById("c");
var ctx = c.getContext("2d");
ctx.fillStyle = "red";
ctx.fillRect(10, 10, 50, 50);
function copy() {
var image = document.getElementById("Img");
image.src = c.toDataURL("image/png");
}<canvas id="c" width="300" height="150" style="border:1px solid #d3d3d3;">
Your browser does not support the HTML5 canvas tag.</canvas>
<img id="Img" width="300" height="150" style="border:1px solid #d3d3d3;"/>
<button onclick="copy()">Copy</button>
加载中,请稍侯......
