从pdf中提取矩形中的文本 - Python

Question

我有一个要求，即从 PDF 中提取矩形中的文本。我已经测试了几种方法。但没有得到特定的文本。例如，我用PyMuPDF，pdfplumber，tabula，camelot，pdftables软件包进行了测试。在PyMuPDF模块中，它要求开始和结束单词来提取文本。据我了解，剩余的包也只是提取线条，曲线信息而不是文本。

我想从 PDF 中的矩形获取文本，而无需提供任何开始和结束文本。

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

Answer 2

您可以使用PyMuPDF 模块中Page.get_textbox的方法。

例如：

import fitz
doc = fitz.open('pdf_test.pdf')
page = doc[0]  # get first page
rect = fitz.Rect(0, 0, 600, page.rect.width)  # define your rectangle here
text = page.get_textbox(rect)  # get text from rectangle
clean_text = ' '.join(text.split())
print(clean_text)
