python关于pdf 操作的一些问题

Question

content = pdf.getPage(page_index)['/Resources']['/XObject'].getObject()
    images = {}
    for obj in content:
        if content[obj]['/Subtype'] == '/Image':
            size = (content[obj]['/Width'], content[obj]['/Height'])
            data = content[obj]._data
            if content[obj]['/ColorSpace'] == '/DeviceRGB':
                mode = "RGB"
            else:
                mode = "P"

            if content[obj]['/Filter'] == '/FlateDecode':
                img = Image.frombytes(mode, size, data)
            else:
                img = Image.open(io.BytesIO(data))
            images[int(obj[3:])] = img
            
            


 pdf = PdfFileReader(open(args.input_pdf_path, "rb"))
    for i in range(0, pdf.getNumPages()):
        logger.info("Processing page {}/{}".format(i + 1, pdf.getNumPages()))
        images_path.append("./temp/{}.jpg".format(i))
        process_page(pdf, i, i < args.skip)

    logger.info('Writing to output PDF file')
    args.output.write(img2pdf.convert(*list(map(img2pdf.input_images, images_path))))
    logger.info('Done')

这里的pdf 是pdf 文件，但是这里的/Resources 和/XObject 不知道啥意思
args.output.write(img2pdf.convert(*list(map(img2pdf.input_images, images_path)))) 这里也不知道啥意思
