CORS issue when using fabric.fromUrl

I am integrating fabricjs with angularjs application. I am pulling an image from a third party source (which is not in my control). I wish to perform some actions on it like: filtering, adding to canvas, storing to canvas and reloading from canvas.

I am using fabric fromurl call with crossorigin but it fails everytime.

 fabric.Image.fromURL('http://img.fkcdn.com/image/dining-chair/b/g/y/fidcbennywncsach-1-cedar-pine-devdar-home-cherry-white-original-imae9fsfbkxrgebt.jpeg', function (img) {
    canvas1.add(img.set({
        left: 50,
        top: 50,
        angle: 30
    }));
    console.log('CORS enabled + crossOrigin property - DataURL: ', canvas1.toDataURL());
}, {
    crossOrigin: 'Anonymous'
});

Fiddle

Is there anything I am doing wrong?

crossOrigin will only request permission to use the resource over CORS but the server can deny it, which in case will also make loading the image fail all together.

The only way around is to upload the image to your own server (no crossOrigin needed) or to use a CORS proxy (crossOrigin still needed) or to upload the image to a host that allows CORS usage (imgur.com and dropbox.com being a couple of examples). All these workaround may involve user right issues.

Why does adding crossOrigin break fabric.Image.fromURL?, I am using a workaround for this for IE10 and older - see below. This keeps all image requests on the same domain, thus passing CORS rules. and cross site scripting can create some issues that can steal identities, etc. In this tutorial, we will learn step by step how to use Angular CLI proxy to fix CORS issues. Step 1 - Prepare your Angular Project. At this step, we expect that you alreay have an Angular project with some code to send HTTP requests and CORS.

Cross-origin Image fabric JS, To get around this using fabric js, Here I am sharing mainly three ways. fabric.​Image.fromURL( URL, function (img) { canvas.add(img); canvas  Fixing CORS Issue in Angular 8/9. Angular server by default serves on localhost:4200 (PORT 4200) and suppose if your backend server is working on different port or domain, then the CORS issue will inevitably occur. Enable CORS with Proxy Configuration Settings in Angular. Now, we are setting proxy in backend.

Try this:

 fabric.Image.fromURL('http://img.fkcdn.com/image/dining-chair/b/g/y/fidcbennywncsach-1-cedar-pine-devdar-home-cherry-white-original-imae9fsfbkxrgebt.jpeg', function (img) {
canvas1.add(img.set({
    left: 50,
    top: 50,
    angle: 30
}));
console.log('CORS enabled + crossOrigin property - DataURL: ', canvas1.toDataURL());}, null,{
crossOrigin: 'Anonymous'});

Add crossOrigin to images loaded by fabric.Image.fromURL to , fromURL to prevent canvas tainting [$35 awarded] #263. Closed. kylemacfarlane opened this issue on Sep 12, 2012 · 21 comments which I haven't tried) now support adding cross domain images to a canvas without tainting it. You could use use-credentials for both but then you'd leak login data to the third party origin. Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served. A web page may freely embed cross-origin images, stylesheets, scripts, iframes, and videos.

CORS access to image error, when loading from remote site using , The best method for those of you using the newer versions of would be to use the fromUrl method of Fabric JS. Cross-origin issues are frustrating when you are stuck, but at  A key difference between a traditional MVC controller and the RESTful web service controller shown earlier is the way that the HTTP response body is created. Rather than relying on a view technology to perform server-side rendering of the greeting data to HTML, this RESTful web service controller populates and returns a Greeting object. The object data is written directly to the HTTP response as JSON.

Fabric JS Tainted Canvas, Image with CORS enabled - IMPORTANT: set crossOrigin property fromURL('​https://s3-eu-west-1.amazonaws.com/kienzle.dev.cors/img/image2.png', function​  When CORS is enabled with the appropriate policy, ASP.NET Core generally automatically responds to CORS preflight requests. See [HttpOptions] attribute for preflight requests. A CORS preflight request might include an Access-Control-Request-Headers header, which indicates to the server the headers that are sent with the actual request.

fabric.js CORS - JSFiddle, I am using fabric.js in order to load images and manipulate them on my canvas (​the fromURL(imgUrl, function(img1){ canvas.add(img1); });. The most common and problematic security issue when implementing CORS is the failure to validate/whitelist requestors. Too often developers set the value for Access-Control-Allow-Origin to  ‘*’. Unfortunately, this is the default. This allows any domain on the web to access that site’s resources.

  • I had to download the images to my server to avoid CORS. +1 for highlighting "crossOrigin will only request permission to use the resource over CORS but the server can deny it, which in case will also make loading the image fail altogether".
  • is it possible to render image from aws s3 bucket on canvas? if yes then please let me know how?
  • Is 'Anonymous' value is case sensitive ?
