从pdf中提取矩形中的文本 - Python

Question

我需要从 Pdf 中提取矩形中的文本。我测试了几种方法。但没有得到具体的文字。例如，我使用 PyMuPDF、pdfplumber、tabula、camelot、pdftables 包进行了测试。在 PyMuPDF 模块中，它要求输入开头和结尾的词来提取文本。据我了解，其余包也只是提取线条、曲线信息，而不是文本。

我想在不提供任何开始和结束文本的情况下从 PDF 中的矩形获取文本。

Answer 1

您可以使用下面的代码

import PyPDF2
def convert_pdf_to_text (document):
    read_pdf = PyPDF2.PdfFileReader(document, strict=False)
    number_of_pages = read_pdf.getNumPages()

    alltext1=""
    for page_number in range(number_of_pages):
        page = read_pdf.getPage(page_number)
        alltext1 += page.extractText()
    return alltext1.replace("\n", "")
convert_pdf_to_text ('pdf_test.pdf')

输出
