我有一個來自圖像子部分的第一個 BufferedImage。我想設(shè)置BufferedImage imageType為BufferedImage.TYPE_3BYTE_BGR使用openjdk8。 final byte[] screenshot = ((TakesScreenshot) Context.getDriver()).getScreenshotAs(OutputType.BYTES); FileUtils.forceMkdir(new File(System.getProperty(USER_DIR) + File.separator + DOWNLOADED_FILES_FOLDER)); InputStream in = new ByteArrayInputStream(screenshot); BufferedImage fullImg = ImageIO.read(in); // Get the location of element on the page Point point = element.getLocation(); // Get width and height of the element int eleWidth = element.getSize().getWidth(); int eleHeight = element.getSize().getHeight(); // Crop the entire page screenshot to get only element screenshot BufferedImage eleScreenshot = fullImg.getSubimage(point.getX(), point.getY(), eleWidth, eleHeight); // ????? BufferedImage bi = new BufferedImage(eleScreenshot.getWidth(), eleScreenshot.getHeight(), BufferedImage.TYPE_3BYTE_BGR); ImageIO.write(eleScreenshot, "jpg", new File(System.getProperty(USER_DIR) + File.separator + DOWNLOADED_FILES_FOLDER + File.separator + screenName + ".jpg");

我通過對象將BufferedImage構(gòu)造函數(shù)與BufferedImage.TYPE_3BYTE_BGR+數(shù)據(jù)副本一起使用Graphics。
BufferedImage eleScreenshot = fullImg.getSubimage(point.getX(), point.getY(), eleWidth, eleHeight);
ImageIO.write(convertType(eleScreenshot, BufferedImage.TYPE_3BYTE_BGR), "jpg", new File(System.getProperty(USER_DIR) + File.separator + DOWNLOADED_FILES_FOLDER + File.separator + screenName + ".jpg"));
private BufferedImage convertType(BufferedImage eleScreenshot, int type) {
BufferedImage bi = new BufferedImage(eleScreenshot.getWidth(), eleScreenshot.getHeight(), type);
Graphics g = bi.getGraphics();
g.drawImage(eleScreenshot, 0, 0, null);
g.dispose();
return bi;
}
