PDFminer，LTCurve TypeError when when

Question

我正在使用这个代码

from pdfminer.layout import LAParams, LTTextBox
from pdfminer.pdfpage import PDFPage
from pdfminer.pdfinterp import PDFResourceManager
from pdfminer.pdfinterp import PDFPageInterpreter
from pdfminer.converter import PDFPageAggregator

fp = open('yourpdf.pdf', 'rb')
rsrcmgr = PDFResourceManager()
laparams = LAParams()
device = PDFPageAggregator(rsrcmgr, laparams=laparams)
interpreter = PDFPageInterpreter(rsrcmgr, device)
pages = PDFPage.get_pages(fp)

for page in pages:
    print('Processing next page...')
    interpreter.process_page(page)
    layout = device.get_result()
    for obj in layout:
        for lobj in obj:
           text =  lobj.get_text()
            print(' text: %s' % text))

我正在使用这个文档：http://www.unixuser.org/~euske/python/pdfminer/programming.html#layout

我不知道为什么我会得到TypeError: 'LTCurve' object is not iterable的任何想法？我想可能是因为我正在尝试获取的LTCurve和LTTextLine处于平行位置，该如何解决？谢谢!

解决了！我必须使用'if isinstance(lobj，LTTextBox)‘(因为LTTextLine与LTTextBOX连接)来显示数据应该从哪里开始，然后我必须显示我需要来自LTTextLine的数据。代码：

for page in pages:
    print('Processing next page...')
    interpreter.process_page(page)
    layout = device.get_result()
    for obj in layout:
        if isinstance(obj,LTTextBox):
           for lobj in obj:
              if isinstance(lobj,LTTextLine):
                  text =  lobj.get_text()
                   print(' text: %s' % text))
