Does anyone know if it's possible to export HTML to PDF using the screenshot feature in Selenium Firefox WebDriver? I have a webpage which has print specific css which I need to download automatically. I understand that the screenshot feature takes a screenshot of the page as an image, but I was looking for a scalable PDF file which is good for print.

推荐答案

Selenium 中的屏幕截图保存为 PNG.PNG和PDF是不同的格式.所以 Selenium 不能将你的 HTML 页面图像直接保存为 PDF.

Screenshots in Selenium are saved as PNG. And PNG and PDF are different kind of formats. So Selenium cannot save your HTML page image directly as a PDF.

但是，您可以尝试插入 Selenium 拍摄的 PNG 屏幕截图并将其添加到 PDF.

But, you could try to insert the PNG screenshot that Selenium takes and add it to a PDF.

检查这个答案.基本上，您将需要一个库(如 itext)并执行以下操作:

Check this answer. Basically, you will need a library (like itext) and do something like:

// Take screenshot
driver.get("http://www.yourwebpage.com");
File screenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(screenshot, new File("screenshot.png"));

// Create the PDF
Document document = new Document(PageSize.A4, 20, 20, 20, 20);
PdfWriter.getInstance(document, new FileOutputStream("my_web.pdf"));
document.open();
Image image = Image.getInstance(getClass().getResource("screenshot.png"));
document.add(image);
document.close();

希望对你有帮助！

由于网络可能非常高，您可能需要查看文档以了解您的情况想要将图像设置为 PDF 文件.

Since webs can be pretty high, you will probably need to check the documentation to see how you want to set your image in a PDF file.
