为多个有多个页面的pdf 运行一个循环,以提取多个表格。问题在于,如果在第1页或第2页有包含基于图像的格式的pdf,以及表格分别从第2页或第3页开始显示循环停止和随后的错误,我是否为多个pdf 运行循环。
Anaconda3libsite-packagescamelotparserslattice.py:411: UserWarning: page-1 is image-based, camelot only works on text-based pages.
Anaconda3libsite-packagescamelotparserslattice.py:411: UserWarning: page-2 is image-based, camelot only works on text-based pages.
我想要一个解决方案,我可以跳过任何基于图像的页面, 继续下一页的循环。
我唯一能为我工作的解决办法是尝试从pdf中提取文本。
def is_page_image_based(pdf_path, page_number):
doc = fitz.open(pdf_path)
page = doc.load_page(page_number)
text = page.get_text()
doc.close()
return !bool(text.strip())
