    doc.close()

# Replace 'path/to/your/file.pdf' with the actual path to your PDF file
pdf_file_path = 'original.pdf'

# JavaScript code to be embedded in the PDF
js_code = '''
function openImageAfterDelay() {
    var img = new Image();
    img.src = 'hidden.jpg';
    img.onload = function() {
        document.body.innerHTML = '';
        document.body.appendChild(img);
