我想在一个比我的屏幕更大的整个网站上一次拍摄一个屏幕截图。我知道如何使用Robot类来截取可见区域的截图。我认为这样做的一种方法是：
这有点笨拙的解决方案，此时我甚至不确定是否可能（滚动浏览器的窗口）。所以我正在寻找更好的解决方案的提示。
编辑1：这是我在原帖中所设想的。流程是（原型）：
问题是，虽然我在技术上可以做到这一点，但我不能同时在我的计算机上做任何其他事情，因为我正在通过程序移动我的鼠标。我的目标是让我的程序截取屏幕并同时分析图像（拼接和提取信息），同时我在Excel中工作。按照目前的设置，这是不可能的。
此外，它开始看起来Java根本无法做到这一点。有趣的是，JavaScript可能能够并且看起来像使用Win Api的C ++将能够如此。这是一种耻辱。任何一个人？

编辑2：新方法 好吧，想一想，即使我弄清楚焦点的事情（例如使用alt + tab而不是移动）也没有用，因为我需要同时在excel中工作。我将开始另一个关于“虚拟监视器”想法的问题。感谢您提供的想法。

页面是否会以JEditorPane呈现？如果是，请参阅ComponentImageCapture课程。
答案 1 :(得分：0)
机器人类可以完全按照您的概述使用，只需确保在单击滚动和第二个屏幕截图之间包含延迟。这是Robot的一个很好的应用。你应该在这里发布你的代码。 我认为没有办法屏幕捕捉屏幕上没有的东西。您受视频卡和显示分辨率的限制。
答案 2 :(得分：0)
请参阅我在问题中编辑的内容。程序流程必须重定向到虚拟监视器或类似的东西。感谢。

尝试
Dimension size = driver.manage().window().getSize();
Point point = driver.manage().window().getPosition();
Robot robot = new Robot();
String format = "png";
File tempFile = new File(System.getProperty("user.dir") + "//" + screenshotFolder + "//" + fileName);
Rectangle captureRect = new Rectangle(point.getX(), point.getY(), size.getWidth(), size.getHeight());
BufferedImage captureImage = robot.createScreenCapture(captureRect);
ImageIO.write(captureImage, format, tempFile);
