 1 | # Qt5PDFViewer
 2 | PDF Viewer with Pyqt5 and pdfjs
 3 | 
 4 | ### Requirements:
 5 | - PyQt5
 6 | - python3
 7 | - pdf.js
 8 | 
 9 | download the latest stable version of pdf.js from the [PDF JS Page](https://mozilla.github.io/pdf.js/getting_started/#download)
10 | 
11 | extract it to the same folder where the script is.
12 | 
13 | ### Usage:
14 | 
15 | > python3 myPDFViever.py /path/to/pdf_file
16 | 
17 | ### using QWebEngineView - myPDFViewer2.py
18 | 
19 | PyQt5 can now show PDF with QWebEngineView
20 | 
21 | > python3 myPDFViever2.py /path/to/pdf_file
