return input;
}
});
trustedURL = policy.createScriptURL('https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js');
} else {
trustedURL = 'https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js';
}
// Load the jsPDF library using the trusted URL.
let jspdf = document.createElement("script");
jspdf.onload = function () {
// Generate a PDF from images with "blob:" sources.
let pdf = new jsPDF();
let elements = document.getElementsByTagName("img");
for (let i = 0; i < elements.length; i++) {
let img = elements[i];
if (!/^blob:/.test(img.src)) {
continue;
}
let canvasElement = document.createElement('canvas');
let con = canvasElement.getContext("2d");
canvasElement.width = img.width;
canvasElement.height = img.height;
con.drawImage(img, 0, 0, img.width, img.height);
let imgData = canvasElement.toDataURL("image/jpeg", 1.0);
pdf.addImage(imgData, 'JPEG', 0, 0);
