python - 使用 Python 将 PDF 转换为图像

Question

我正在尝试在我安装的 ubuntu 服务器中将 pdf 文件转换为图像文件:

1. python2.7
2. poppler-utils
3. pdf2image==1.12.1

我的代码:

from pdf2image import convert_from_path, convert_from_bytes

images = convert_from_path("/home/user/pdf_file.pdf")

# OR

with open("/home/user/pdf_file.pdf") as pdf:
    images = convert_from_bytes(pdf.read())

输出

当我使用“convert_from_path”函数时

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/pdf2image/pdf2image.py", line 143, in convert_from_path
    thread_output_file = next(output_file)
TypeError: ThreadSafeGenerator object is not an iterator

当我使用“convert_from_bytes”函数时

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "/usr/local/lib/python2.7/dist-packages/pdf2image/pdf2image.py", line 268, in convert_from_bytes
    paths_only=paths_only,
  File "/usr/local/lib/python2.7/dist-packages/pdf2image/pdf2image.py", line 143, in convert_from_path
    thread_output_file = next(output_file)
TypeError: ThreadSafeGenerator object is not an iterator

我已经重新安装了所有实用程序，然后我遇到了这些问题。

如果您想将 PDF 转换为图像，您可以尝试 Python Ghostscript package :

pip install ghostscript

import ghostscript
import locale

def pdf2jpeg(pdf_input_path, jpeg_output_path):
    args = ["pef2jpeg", # actual value doesn't matter
            "-dNOPAUSE",
            "-sDEVICE=jpeg",
            "-r144",
            "-sOutputFile=" + jpeg_output_path,
            pdf_input_path]

    encoding = locale.getpreferredencoding()
    args = [a.encode(encoding) for a in args]

    ghostscript.Ghostscript(*args)

pdf2jpeg(
    "...Fixate/ActiveState/pdf/a.pdf",
    "...Fixate/ActiveState/pdf/a.jpeg",
)
