What are the steps to successfully install OpenCV (javascript edition) on Internet Explorer 11?

I'm currently experiencing issues with getting the OpenCV javascript version to function properly on IE11 for contour detection. While my code runs smoothly on all other up-to-date browsers, I am encountering errors such as:

TypeError: Object doesn't support this action

The error within the OpenCV library occurs at the following line of code:

var imgData=new ImageData(new Uint8ClampedArray(img.data),img.cols,img.rows);

It appears that IE11 does not support this syntax. I have attempted to search for a polyfill solution to resolve this issue, but have had no success thus far.

If anyone has insights on how to resolve this compatibility problem with IE11, your assistance would be greatly appreciated.

Thank you.

Answer №1

Unfortunately, Internet Explorer does not support the ImageData() constructor. However, there is a workaround - you can use the CanvasRenderingContext2D.createImageData() method to create the ImageData object instead.

Here's an example of how to do this:

const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');

const imageData = ctx.createImageData(100, 50);
console.log(imageData);
// ImageData { width: 100, height: 50, data: Uint8ClampedArray[20000] }
