这是我现有的代码,允许我将网页保存为图像。我需要以这样一种方式保存网页,我可以将其打印到A4纸上
目前,该网页的屏幕截图相当长(高度),因此必须在多个网页上显示。如果要将网页另存为pdf,请使用: 编辑: 如果您使用的是Windows,则可以通过以下方式提高质量:
printer = QtGui.QPrinter(QtGui.QPrinter.HighResolution)
谢谢顺便说一句,当我打开代码生成的report.pdf时,它有点模糊,我几乎需要200%的缩放才能使文本更清晰。“你知道怎么解决这个问题吗?”创造者说。我尝试了一些随机页面,没有得到任何明显的模糊。我在我的答案中添加了一个可能的解决方案,如果您使用Windows,该解决方案可能会有所帮助。@TheCreator 232:我已经尝试了您的两种方法,保存为png和保存为pdf。在我看来,最好使用save to png结果,然后——在某种程度上——将长的png分割成png,然后将它们组合起来创建一个多页的PDF。这将创造一个像素完美的屏幕抓拍结果(这实际上是我的意图)感谢这篇文章!
printer = QtGui.QPrinter(QtGui.QPrinter.HighResolution)
