python实现带图形界面的图片类型的pdf转word

可以使用Python的三方库PyQt和pdfminer来实现带图形界面的图片类型的PDF转Word。具体步骤如下：

1. 安装PyQt和pdfminer库

pip install PyQt5
pip install pdfminer

2. 构建图形界面

可以使用Qt Designer来构建简单的图形界面，然后将其转换成Python代码。这里给出一个简单的示例代码：

from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QFileDialog, QLabel
from PyQt5.QtGui import QPixmap
import sys

class App(QWidget):
    def __init__(self):
        super().__init__()
        self.title = 'PDF转Word'
        self.left = 100
        self.top = 100
        self.width = 640
        self.height = 480
        self.initUI()

    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)

        self.button = QPushButton('选择PDF文件', self)
        self.button.move(50, 50)
        self.button.clicked.connect(self.openFileDialog)

        self.label = QLabel(self)
        self.label.move(50, 100)
        self.label.resize(200, 200)

        self.show()

    def openFileDialog(self):
        fileName, _ = QFileDialog.getOpenFileName(self, "选择PDF文件", "", "PDF Files (*.pdf)")
        if fileName:
            self.convertPDFtoWord(fileName)

    def convertPDFtoWord(self, fileName):
        # TODO: 实现PDF转Word的功能
        pixmap = QPixmap('example.png')
        self.label.setPixmap(pixmap)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

3. 实现PDF转Word的功能

使用pdfminer库来解析PDF文件，找到其中的图片，并将其转换成Word中的图片格式。具体代码如下：

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter, PDFPageAggregator
from pdfminer.layout import LAParams, LTTextBoxHorizontal, LTTextBoxVertical, LTTextLine, LTImage, LTFigure
from pdfminer.pdfpage import PDFPage
from io import StringIO
import os
from PIL import Image

def convertPDFtoWord(pdfFileName):
    pdf = open(pdfFileName, 'rb')
    rsrcmgr = PDFResourceManager()
    laparams = LAParams()
    device = PDFPageAggregator(rsrcmgr, laparams=laparams)
    interpreter = PDFPageInterpreter(rsrcmgr, device)

    # 循环遍历每一页
    for page in PDFPage.get_pages(pdf):
        interpreter.process_page(page)
        layout = device.get_result()

        # 循环遍历每一个layout对象
        for lt_obj in layout:
            if isinstance(lt_obj, LTImage):
                # 如果是图片，将其转换为Word中的图片格式
                x, y, w, h = lt_obj.bbox
                img = Image.open(StringIO(lt_obj.stream.get_rawdata()))
                img.save('example.png')

    pdf.close()

将上述代码添加到App类中，完整代码如下：

from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QFileDialog, QLabel
from PyQt5.QtGui import QPixmap
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter, PDFPageAggregator
from pdfminer.layout import LAParams, LTTextBoxHorizontal, LTTextBoxVertical, LTTextLine, LTImage, LTFigure
from pdfminer.pdfpage import PDFPage
from io import StringIO
import os
from PIL import Image
import sys

class App(QWidget):
    def __init__(self):
        super().__init__()
        self.title = 'PDF转Word'
        self.left = 100
        self.top = 100
        self.width = 640
        self.height = 480
        self.initUI()

    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)

        self.button = QPushButton('选择PDF文件', self)
        self.button.move(50, 50)
        self.button.clicked.connect(self.openFileDialog)

        self.label = QLabel(self)
        self.label.move(50, 100)
        self.label.resize(200, 200)

        self.show()

    def openFileDialog(self):
        fileName, _ = QFileDialog.getOpenFileName(self, "选择PDF文件", "", "PDF Files (*.pdf)")
        if fileName:
            self.convertPDFtoWord(fileName)

    def convertPDFtoWord(self, pdfFileName):
        pdf = open(pdfFileName, 'rb')
        rsrcmgr = PDFResourceManager()
        laparams = LAParams()
        device = PDFPageAggregator(rsrcmgr, laparams=laparams)
        interpreter = PDFPageInterpreter(rsrcmgr, device)

        # 循环遍历每一页
        for page in PDFPage.get_pages(pdf):
            interpreter.process_page(page)
            layout = device.get_result()

            # 循环遍历每一个layout对象
            for lt_obj in layout:
                if isinstance(lt_obj, LTImage):
                    # 如果是图片，将其转换为Word中的图片格式
                    x, y, w, h = lt_obj.bbox
                    img = Image.open(StringIO(lt_obj.stream.get_rawdata()))
                    img.save('example.png')
                    pixmap = QPixmap('example.png')
                    self.label.setPixmap(pixmap)

        pdf.close()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

注意：这里只是对图片进行了转换，并没有将PDF文件转换成Word文件。如果需要将PDF文件转换成Word文件，可以使用docxpy库。
