I'm attempting to capture a screenshot of the entire visible page in an Ionic Vue app, but I keep encountering the error "Cannot find name 'ImageCapture'".
const stream = await navigator.mediaDevices.getDisplayMedia();
const screenVideoTrack = stream.getVideoTracks()[0];
console.log("screenVideoTrack", screenVideoTrack);
const capture = new ImageCapture(screenVideoTrack); // this is where the error occurs
// when you need the still image
const bitmap = await capture.grabFrame();
// if you want a Blob version
const canvas = document.createElement("canvas");
if (!canvas) {
console.error("no canvas created");
return;
}
canvas.width = bitmap.width;
canvas.height = bitmap.height;
canvas.getContext("bitmaprenderer")?.transferFromImageBitmap(bitmap);
const blob = await new Promise((res) => canvas.toBlob(res));
I have installed "@types/w3c-image-capture": "^1.0.5" via npm. The error arises during compilation rather than execution (it cannot be executed if not compiled correctly).
How can I make Ionic Vue recognize that this type exists?
Is there an alternative method for capturing a screenshot of the entire page? (I prefer not to use the 'html2canvas' library)
