在 Centos 8 操作系统上，使用 Python 将 pdf 页面转换为 jpg 文件时出现错误。
from pdf2image import convert_from_path
import sys
images = convert_from_path("test.pdf",500)
for i in range(len(images)):
images[i].save('page'+ str(i) +'.jpg', 'JPEG')
Traceback (most recent call last):
File "/usr/local/lib/python3.6/site-packages/pdf2image/pdf2image.py", line 479, in pdfinfo_from_path
raise ValueError

最佳答案
PDF != PDF - 它有不同的版本。愿你的 python pdf2image不喜欢/不知道您提供的 PDF 类型。使用 AcrobatReader 或类似工具检查您要转换的内容，看看是否 pdf2image支持它。
见 Which ISO standards does pdf2image support (简称:pdf2image supports all PDF standards that poppler supports.)
