#!/usr/bin/python3 # -*- coding: utf-8 -*- import sys import os from PyQt5.QtWidgets import QApplication from PyQt5.QtCore import QUrl from PyQt5.QtWebEngineWidgets import QWebEngineView PDFJS = f"file://{os.path.abspath('./web/viewer.html')}" print(PDFJS) PDF = f'file://{"%20".join(sys.argv[1:])}' print("loading PDF:", PDF) class Window(QWebEngineView): def __init__(self): super(Window, self).__init__() self.load(QUrl.fromUserInput(f'{PDFJS}?file={PDF}')) if __name__ == '__main__': app = QApplication(sys.argv) window = Window() window.showMaximized() sys.exit(app.exec_()) |
And now if you execute the above script by typing the below command as shown below
python app.py sample.pdf
So here we are providing the path of the input pdf file inside the command as shown above
