使用Python统计PDF中的图像数量

import PyPDF2
from PIL import Image

pdf_file = open('your_pdf_file.pdf', 'rb')
pdf_reader = PyPDF2.PdfFileReader(pdf_file)

def count_images(page):
    image_count = 0
    try:
        xObject = page['/Resources']['/XObject'].getObject()
        for obj in xObject:
            if xObject[obj]['/Subtype'] == '/Image':
                image_count += 1
    except KeyError:
        pass
    return image_count

total_image_count = 0
for page_num in range(pdf_reader.numPages):
    page = pdf_reader.getPage(page_num)
    total_image_count += count_images(page)

print("PDF中的图像数量：", total_image_count)
