可以使用Python的第三方库PyPDF2和python-docx来实现图片型PDF文件转Word文件的功能。以下是示例代码:
import os
from PIL import Image
import pytesseract
import PyPDF2
from docx import Document
from docx.shared import Inches
# 定义图片转文字函数
def img_to_text(img_path):
img = Image.open(img_path)
text = pytesseract.image_to_string(img, lang='chi_sim')
return text
# 定义PDF转Word函数
def pdf_to_word(pdf_path, word_path):
pdf_file = open(pdf_path, 'rb')
pdf_reader = PyPDF2.PdfFileReader(pdf_file)
doc = Document()
for page in range(pdf_reader.getNumPages()):
page_obj = pdf_reader.getPage(page)
text = page_obj.extractText()
img_list = []
for obj in page_obj['/Resources']['/XObject'].values():
if obj['/Subtype'] == '/Image':
img_name = obj['/Name']
img_stream = obj['/Stream'].getData()
img_path = os.path.join(os.path.dirname(pdf_path), img_name + '.jpg')
with open(img_path, 'wb') as f:
f.write(img_stream)
img_list.append(img_path)
for img_path in img_list:
text += img_to_text(img_path)
os.remove(img_path)
doc.add_paragraph(text)
doc.add_page_break()
doc.save(word_path)
# 测试
pdf_path = 'test.pdf'
word_path = 'test.docx'
pdf_to_word(pdf_path, word_path)
注意:在运行代码之前,需要先安装PyPDF2、python-docx、Pillow和pytesseract这些第三方库。另外,由于图片转文字需要使用OCR技术,所以需要安装Tesseract OCR引擎,并将其路径添加到系统环境变量中。
