How to convert webpage into PDF by using Python
I was finding solution to print webpage into local file PDF, using Python. one of the good solution is to use Qt, found here, https://bharatikunal.wordpress.com/2010/01/.
It didn't work at the beginning as I had problem with the installation of PyQt4 because it gave error messages such as 'ImportError: No module named PyQt4.QtCore', and 'ImportError: No module named PyQt4.QtCore'.
It was because PyQt4's not installed properly. I used to have the libraries located at C:\Python27\Lib however it's not for PyQt4.
In fact, it simply needs to download from http://www.riverbankcomputing.com/software/pyqt/download (mind the correct Python version you are using), and install it to C:\Python27 (my case). That's it.
Now the scripts runs fine so I want to share it. for more options in using Qprinter, please refer to http://qt-project.org/doc/qt-4.8/qprinter.html#Orientation-enum.
thanks to below posts, and I am able to add on the webpage link address to be printed and present time on the PDF generated, no matter how many pages it has.
To share the script as below:
import time from pyPdf import PdfFileWriter, PdfFileReader import StringIO from reportlab.pdfgen import canvas from reportlab.lib.pagesizes import letter from xhtml2pdf import pisa import sys from PyQt4.QtCore import * from PyQt4.QtGui import * from PyQt4.QtWebKit import * url = 'http://www.yahoo.com' tem_pdf = "c:\\tem_pdf.pdf" final_file = "c:\\younameit.pdf" app = QApplication(sys.argv) web = QWebView() #Read the URL given web.load(QUrl(url)) printer = QPrinter() #setting format printer.setPageSize(QPrinter.A4) printer.setOrientation(QPrinter.Landscape) printer.setOutputFormat(QPrinter.PdfFormat) #export file as c:\tem_pdf.pdf printer.setOutputFileName(tem_pdf) def convertIt(): web.print_(printer) QApplication.exit() QObject.connect(web, SIGNAL("loadFinished(bool)"), convertIt) app.exec_() sys.exit # Below is to add on the weblink as text and present date&time on PDF generated outputPDF = PdfFileWriter() packet = StringIO.StringIO() # create a new PDF with Reportlab can = canvas.Canvas(packet, pagesize=letter) can.setFont("Helvetica", 9) # Writting the new line oknow = time.strftime("%a, %d %b %Y %H:%M") can.drawString(5, 2, url) can.drawString(605, 2, oknow) can.save() #move to the beginning of the StringIO buffer packet.seek(0) new_pdf = PdfFileReader(packet) # read your existing PDF existing_pdf = PdfFileReader(file(tem_pdf, "rb")) pages = existing_pdf.getNumPages() output = PdfFileWriter() # add the "watermark" (which is the new pdf) on the existing page for x in range(0,pages): page = existing_pdf.getPage(x) page.mergePage(new_pdf.getPage(0)) output.addPage(page) # finally, write "output" to a real file outputStream = file(final_file, "wb") output.write(outputStream) outputStream.close() print final_file, 'is ready.'
