html2canvas does not render images located in the element

[ghost]

Let's say if I would add text and a background color, then I'd press save, it would show the text and background color, but if I add an image into the div it won't show the image, but still the other things.

Hi.
I have exactly the same problem.

[jayantbh]

Same issue here.
I'm trying to get the shot of a tweet, and the attached image doesn't come through.
Image attached.

[ryanabooth]

I believe images from other sites are blocked by default because it "taints the HTML5 canvas". Here is the option you need to use when you call the renderer:

attribute: allowTaint
type: boolean
default: false
description: Whether to allow cross-origin images to taint the canvas

Found it here: https://html2canvas.hertzen.com/documentation.html.

same problem....
and my images are coming from same orign

[sky1508]

I have faced the same issue, the best way to solve the issue is to run the project on the server and see the result.
In my case, earlier i was running the html files directly without any server, but then after googling a bit i got a solution to try it on a server.
I tried my project using Visual Studio and it was running perfectly, my images inside div tag was also being copied

[SebasAlvarez]

Insert de option allowTaint to view all images into your screenshot

html2canvas(document.getElementById('invoice-panel'), { letterRendering: 1, allowTaint : true, onrendered : function (canvas) { } });

[sandeepnagra]

@SebasAlvarez - the allowTaint option doesn't work anymore. Does it still work for you?

[venkateshduddu]

@SebasAlvarez , @sandeepnagra :
am using this code for image screenshot in new tab but image not rendering and also i tired with "allowTaint:true" it's working only in inside same window but not in new tab.
this is my code:
function render(){
html2canvas(document.body, { allowTaint : true,
onrendered: function(canvas) {
document.body.appendChild(canvas);
window.open(canvas.toDataURL());
}
});
}
can you tell me what is the problem, how can you fix this one??

[sandeepnagra]

@venkateshduddu - are you shifting the focus to new tab first before taking screenshot?

[venkateshduddu]

@sandeepnagra - no sandeep, am just using click event. one more thing screenshot working if i use local image path but server path not working in new tab.

[sandeepnagra]

@venkateshduddu - a click event won't shift the focus to new tab automatically, you have to trigger that. So try that first, I am 100% sure it will solve your issue.

Regarding the server path, is that network drive authenticated? If yes, are you authenticating before uploading files to the network drive? It's a whole different story if you want to upload them to S3 bucket.

var imgData = canvas.toDataURL('image/jpeg');
});

[trungegd]

Insert de option allowTaint to view all images into your screenshot

Thanks. It works fine.

But I can't clone image style to canvas

[Swathi178]

I still face the same issue even after using above options below is my code.

allowTaint: false,
useCORS: true
}).then(canvasElm => {
var imageType = "image/png";
var imageData = canvasElm.toDataURL(imageType);
var src = encodeURI(imageData);
console.log("src", src);
console.log("image Data", imageData);

same issue with me any help

[kkozler]

I'm seeing the same issue. What am I doing wrong?

html2canvas(document.getElementById(<id>), {
	logging: true,
	letterRendering: 1,
	allowTaint: false,
	useCORS: true
}).then(result => {
	var img = result.toDataURL("image/png");
	savePng(img);
});

[SylarRuby]

The below also works if you want to include <img src-"..." />:

html2canvas(report, {letterRendering: 1, allowTaint: true, useCORS: true})
            .then((canvas) => {      
                const imgData = canvas.toDataURL('image/png');
               // const pdf = new jsPDF();
               // pdf.addImage(imgData, 'PNG', 10, 10);
                //pdf.save("foo.pdf");  
            });

[venkateshCorezi]

My content is contains image that come from Aws.s3(). The above mentioned Comments are not working for my case.

html2canvas(content, {letterRendering: 1,allowTaint: false,useCORS:true })
.then(canvas => {
const imgData = canvas.toDataURL('image/png');
console.log(imgData);
const pdf = new jsPDF();
pdf.addImage(imgData, 'PNG', 10, 10, canvas.width, canvas.height);
pdf.save('download.pdf');
});

The output canvas only contains a blank box instead of image. Any one have a solution for my case?

It works for me ❤❤

[Vishal-Kank]

Access to image at 'https://image/logo link' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Is this the reason why my logo is not appearing in the pdf file.
Rest all the text with css applied and the brand logo which is in my static folder is comming.
Please do answer need help on this Iam trying this from more than 2 weeks.

[khaiquangnguyen]

For anyone coming here, after trying many things, I found out that for getting images from an external resources ( such as S3 bucket), you have to enable both useCORS = true for html2canvas, and enable CORS policy on the images served from S3.

[zeusstl]

I resolved it using the html2canvas proxy. You can see some details on usage and testing here:
https://github.com/zeusstl/html2canvas-proxy-nodejs

[thetnaingtn]

I also had that kind of issue. But now I think I have a solution. Before adding an image to canvas add crossOrigin = 'Anonymous' to the image.Like that:
let img = new Image();
img.src = url;
img.crossOrigin = 'Anonymous';

I hope that will also work for you!

[hanifkumara]

@Sotyoyo Alhamdulillah, thank you broo

[SalahAdDin]

It does not work with early versions.

useCORS: true

[ogheneovo12]

html2canvas doesn't evaluate srcset rules and uses only the src values, it also ignores the object-fit style of images

[SalahAdDin]

why?

[ogheneovo12]

html2canvas doesn't evaluate srcset rules and uses only the src values, it also ignores the object-fit style of images

why?

Went through the doc and saw that object-fit wasn’t supported, had to switch to media queries instead of the using srcsets rules as there’s no specification that states if html2canvas considers that when processing images.

[Diegoafv]

Still getting the same issue.

[rrfaria]

I found out what is happen even using useCORS.
I used 2 different images to see how it performs.
One with cors allwoing cors anonymously and other without permission

// img 1- with cors blocked but rendering on html and not downloading using html2canvas
<img
 src="https://a-static.mlcdn.com.br/618x463/kit-gamer-razer-battle-bundle-mouse-deathadder-v2-headset-gamer-blackshark-v2-x-mousepad-gigant/formatameupc/kitrz/a78905f66dd2f260c5daa60dd726c80a.jpeg"
 >
 
 //  img 2- with cors allowed and download using html2canvas
 <img
 src="https://lh3.googleusercontent.com/acezh821GREUTqwpxvzCnLtRfEkmkLF1aHSj3d8RYRFMvdCA0KL-9IN7XvJnke2agLv3pq-dpU2ceTehC3MFB22EnOgps0UbLVU0ujg=w600"
 crossorigin="anonymous"
 >

html2canvas(div, {
 letterRendering: 1,
 logging: true,
 letterRendering: 1,
 useCORS: true,
}).then(function(canvas) {
 var myImage = canvas.toDataURL();
 downloadURI(myImage, "promo.png");
});
function downloadURI(uri, name) {
 var link = document.createElement("a");

 link.download = name;
 link.href = uri;
 document.body.appendChild(link);
 link.click();
 //after creating link you should delete dynamic link
}

the problem is:
img 1 has no cors enabled on server but it still rendering on html.
I can see it on my rendered html but when I click to start html2canavas it doesn't exports the image.
if I set crossorigin="anonymous" then I can't see on html rendered and also can't download.

Now if I use img 2 with crossorigin="anonymous" it's renders on html and also download.

And the error I think everyone is having is because we don't have control of the server to allow cors, but we still see html rendered with the image and since it's rendered we believe it can be downloaded.

I shared this to see if someone have any insight how to solve it

[Bawanthathilan]

Still getting the same issue.

me too
