如何使用 selenium java 进行彩色截图

Question

屏幕截图如下图所示，但我想在实际 colors 中捕获它，我也不知道它背后的原因，谁能告诉我为什么会这样？

 ((JavascriptExecutor)driver).executeScript("window.scrollBy(0,131)");
 int yPosition = Decision_Maker.getLocation().getY();
 for(int j = 1; j<=list.size(); j++)
 {
            // Get entire page screenshot
            File screenshots = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
            BufferedImage  fullImg = ImageIO.read(screenshots);
            ImageIO.read(screenshots).getHeight();
            // Get width and height of the element
            int eleWidth =  Decision_Maker.getSize().getWidth();
            int eleHeight = Decision_Maker.getSize().getHeight();
            //Crop the entire page screenshot to get only element screenshot
            BufferedImage eleScreenshot= fullImg.getSubimage(465, 190,eleWidth,eleHeight);
            ImageIO.write(eleScreenshot, "jpg", screenshots);

                //Scroll vertically to the element
                JavascriptExecutor js = (JavascriptExecutor) driver;
                js.executeScript("window.scroll (0, " + yPosition + ") ");
               
                yPosition = yPosition + eleHeight;  
                //wait for sometime
                Thread.sleep(3000);
                
                //File Location
                String location = "E:\\Automation\\Screenshots\\";              
                Thread.sleep(3000);
                    
                //capture screenshot
                FileUtils.copyFile(screenshots, new File (location + "img" + i + ".jpg"));
                Thread.sleep(3000L);
             }

您可以创建 utils class 来截取屏幕截图并使用它

  public static void TakeScreenshot(String filename) throws IOException
{
    File file= ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
    FileUtils.copyFile(file, new File("path to store screenshot" + filename + ".jpg"));
}
