Can I get image from canvas element and use it in img src tag?

canvas.toDataURL() will provide you a data url which can be used as source:

var image = new Image();
image.id = "pic";
image.src = canvas.toDataURL();
document.getElementById('image_for_crop').appendChild(image);

Complete example

Here's a complete example with some random lines. The black-bordered image is generated on a <canvas>, whereas the blue-bordered image is a copy in a <img>, filled with the <canvas>'s data url.

// This is just image generation, skip to DATAURL: below var canvas = document.getElementById("canvas") var ctx = canvas.getContext("2d"); // Just some example drawings var gradient = ctx.createLinearGradient(0, 0, 200, 100); gradient.addColorStop("0", "#ff0000"); gradient.addColorStop("0.5" ,"#00a0ff"); gradient.addColorStop("1.0", "#f0bf00"); ctx.beginPath(); ctx.moveTo(0, 0); for (let i = 0; i < 30; ++i) { ctx.lineTo(Math.random() * 200, Math.random() * 100); } ctx.strokeStyle = gradient; ctx.stroke(); // DATAURL: Actual image generation via data url var target = new Image(); target.src = canvas.toDataURL(); document.getElementById('result').appendChild(target); canvas { border: 1px solid black; } img { border: 1px solid blue; } body { display: flex; } div + div {margin-left: 1ex; }

Do this. Add this to the bottom of your doc just before you close the body tag.

<script>
    function canvasToImg() {
      var canvas = document.getElementById("yourCanvasID");
      var ctx=canvas.getContext("2d");
      //draw a red box
      ctx.fillStyle="#FF0000";
      ctx.fillRect(10,10,30,30);

      var url = canvas.toDataURL();

      var newImg = document.createElement("img"); // create img tag
      newImg.src = url;
      document.body.appendChild(newImg); // add to end of your document
    }

    canvasToImg(); //execute the function
</script>

Of course somewhere in your doc you need the canvas tag that it will grab.

<canvas id="yourCanvasID" />

I´ve found two problems with your Fiddle, one of the problems is first in Zeta´s answer.

the method is not toDataUrl(); is toDataURL(); and you forgot to store the canvas in your variable.

So the Fiddle now works fine http://jsfiddle.net/gfyWK/12/

I hope this helps!

canvas.toDataURL is not working if the original image URL (either relative or absolute) does not belong to the same domain as the web page. Tested from a bookmarklet and a simple javascript in the web page containing the images. Have a look to David Walsh working example. Put the html and images on your own web server, switch original image to relative or absolute URL, change to an external image URL. Only the first two cases are working.

Corrected the Fiddle - updated shows the Image duplicated into the Canvas...

And right click can be saved as a .PNG

http://jsfiddle.net/gfyWK/67/

<div style="text-align:center">
<img src="http://imgon.net/di-M7Z9.jpg" id="picture" style="display:none;" />
<br />
<div id="for_jcrop">here the image should apear</div>
<canvas id="rotate" style="border:5px double black; margin-top:5px; "></canvas>
</div>

Plus the JS on the fiddle page...

Cheers Si

Currently looking at saving this to File on the server --- ASP.net C# (.aspx web form page) Any advice would be cool....
