Есть pdf документ, содержащий несколько страниц, на каждой из которых есть текст и изображение. Мне необходимо извлечь изображение. Использую python и библиотеку fitz. При попытках извлечь изображение из ‘/XObject’ извлекается изображение, содержащие 1 пиксель, используемое, видимо, как маска, а само изображение извлечь не получается. Содержание страницы следующее:
1 0 obj

(page.Resources.XObject) выдает следующий результат:
{‘Xf1′: <Stream:len=11510,data=b’xx9cxc5|xcbx0e-;xb2xd4|x7fxc5xf9x02TxcbNxbb\xbfx80xc4x80x11 …’>,

Как мне извлечь изображение, содержащееся в ‘Xf1’?

`import fitz
from PIL import Image
import io

pdf_path = ‘1.pdf’

pdf_document = fitz.open(pdf_path)

for page_num in range(pdf_document.page_count):
page = pdf_document[page_num]

# Извлекаем текст из каждой страницы
text = page.get_text("text")
print(f"Текст на странице {page_num+1}: {text}")

# Извлекаем изображения из каждой страницы
images = page.get_images(full=True)
for img_index, img_info in enumerate(images):
    xref = img_info[0]
    base_image = pdf_document.extract_image(xref)
    image_bytes = base_image["image"]
    image = Image.open(io.BytesIO(image_bytes))
    if image.mode == 'RGBA':
        image = image.convert('RGB')
    image.save(f"page_{page_num}_image_{img_index}.jpg")

pdf_document.close()`
