인쇄 웹 페이지 QtWebKit.webView에서 PDF로 PyQt4

Question

안녕하세요, 나는 특정 웹 사이트를 표시하는 사용자 지정 QtWebKit.QWebView가있는 QWidget이 있습니다. 파이썬과 PyQt를 사용하여 pdf로 웹 페이지를 저장하고 싶습니다.

from PyQt4 import QtCore, QtGui 
from PyQt4 import QtWebKit 
from Save_Evidence import * 
import sys 

##### Custom WebView ############# 
class Browser(QtWebKit.QWebView): 

    def __init__(self,parent =None): 
     QtWebKit.QWebView.__init__(self,parent) 
     self.loadFinished.connect(self._result_available) 

    def _result_available(self, ok): 
    frame = self.page().mainFrame() 
    self.html = unicode(frame.toHtml()).encode('utf-8')

    _fromUtf8 = QtCore.QString.fromUtf8

    _fromUtf8 = lambda s: s 

class Ui_Form(QtGui.QWidget): 
    def setupUi(self, Form): 
     Form.setObjectName(_fromUtf8("Form")) 
     Form.resize(640, 480) 
     self.gridLayout = QtGui.QGridLayout(Form) 
     self.gridLayout.setObjectName(_fromUtf8("gridLayout")) 
     self.verticalLayout = QtGui.QVBoxLayout() 
     self.verticalLayout.setObjectName(_fromUtf8("verticalLayout")) 
     self.webView = Browser(Form) 
     self.webView.setUrl(QtCore.QUrl(_fromUtf8("https://malwr.com/submission/"))) 
     self.webView.setObjectName(_fromUtf8("webView")) 
     self.verticalLayout.addWidget(self.webView) 
     self.horizontalLayout = QtGui.QHBoxLayout()

     self.pushButton.setText(QtGui.QApplication.translate("Form", "Save Report", None, QtGui.QApplication.UnicodeUTF8)) 



    def printIt(self, val): 
     if str(self.webView.url().toString()).find("https://malwr.com/analysis/") == 0: 
      xpage = self.webView.page() 
      self.HTML = unicode(xpage. currentFrame().toHtml()).encode('utf-8') 
      f =xpage. currentFrame().contentsSize() 
      self.pushButton.setEnabled(True) 

    def saveReport(self): 
     self.webView.page().setViewportSize(xpage. currentFrame().contentsSize()) 
     image = QtGui.QImage(self.webView.page().viewportSize(),QtGui.QImage.Format_ARGB32) 
     painter = QtGui.QPainter(image) 
     self.webView.page().mainFrame().render(painter) 
     painter.end() 
     image.save(QtCore.QString("output-report"),"png") 
     output = QtCore.QFile() 
     output.open(1, QtCore.QIODevice.WriteOnly) 
     image.save(output, 'PNG') 




class MyForm(QtGui.QWidget): 
     def __init__(self, parent=None): 
      QtGui.QWidget.__init__(self, parent) 
      self.ui = Ui_Form() 
      self.ui.setupUi(self) 


if __name__ == "__main__": 
    app = QtGui.QApplication(sys.argv) 
    myapp = MyForm() 
    myapp.show() 
    sys.exit(app.exec_()) 

이것은 내 기존 코드이므로 웹 페이지를 이미지로 저장할 수 있습니다. 웹 페이지를 그런 방식으로 저장해야합니다. A4 용지에 인쇄 할 수 있습니다.

지금 웹 페이지의 스크린 샷은 매우 길어서 한 페이지 이상에 표시되어야합니다. 당신은 PDF로 웹 페이지를 저장하려면

Answer 1

, QPrinter 사용

printer = QtGui.QPrinter() 
    printer.setPageSize(QtGui.QPrinter.A4) 
    printer.setColorMode(QtGui.QPrinter.Color) 
    printer.setOutputFormat(QtGui.QPrinter.PdfFormat) 
    printer.setOutputFileName('report.pdf') 
    self.page().mainFrame().print_(printer) 

편집 : Windows에서 경우

것은, 당신이 품질을 향상시킬 수 있습니다을 :

printer = QtGui.QPrinter(QtGui.QPrinter.HighResolution)
