python pdf2image“可能不是 PDF 文件”錯誤

Question

在 Centos 8 操作系統上，使用 Python 將 pdf 頁轉換為 jpg 文件時出現錯誤。

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')

結果它給出了這個錯誤。 我可以在本地運行PDF文件，但是當我想將它保存為jpg時它不起作用。

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/pdf2image/pdf2image.py", line 479, in pdfinfo_from_path
    raise ValueError
ValueError

During handling of the above exception, another exception occurred:

    images = convert_from_path(pdf_path,500)

PDF.= PDF - 它有不同的版本。 也許你的 python pdf2image不喜歡/不知道你喂它的那種PDF。 使用 AcrobatReader 或類似軟件來檢查您要轉換的內容並查看pdf2image是否支持它。
