Cross-origin error from canvas.ctx.getImageData() #47

Closed shubckin closed 3 years ago

shubckin commented 5 years ago

When i call method getImageData from canvas, i get error: "Unable to get image data from canvas because the canvas has been tainted by cross-origin data". Example to reproduce this error: function testCanvas(src) { var canvas = document.createElement("canvas"); var img = new Image(); img.addEventListener("load", function () { canvas.getContext("2d").drawImage(img, 0, 0, img.width, img.height, 0, 0, canvas.width, canvas.height); canvas.getContext("2d").getImageData(0,0,img.width, img.height); canvas.toDataURL(); }); img.setAttribute("src", src); }

@shubckin We will analyse the reported the issue and get back to you.

I have the same problem.... also all my Javascript files that are included in the main index.html are treated as cross-origin resources, therefore I get no detailed Javascript errors.

I hope there will be a solution for all this nightmare soon. :-)
