這裏是一個Python程序，將一個提供網頁保存爲圖像：http://pastie.org/4572412

這應該是主要感興趣的部分，您：

size = self.browser.mainFrame().contentsSize() 
    if width > 0: 
     size.setWidth(width) 
    self.browser.setViewportSize(size) 

    # Render the virtual browsers viewport to an image. 
    image = QImage(self.browser.viewportSize(), QImage.Format_ARGB32) 
    paint = QPainter(image) #Have the painters target be our image object 
    self.browser.mainFrame().render(paint) #Render browser window to painter 
    paint.end() 
    image = image.scaledToWidth(width) #ensure the image is your desired width 
    extension = os.path.splitext(filename)[1][1:].upper() #save the file as your desired image extension 
    if extension not in self.image_extensions: 
     raise ValueError("'filename' must be a valid extension: {0}".format(self.image_extensions)) 
    image.save(filename, extension) 

希望這有助於！
