有些微信图片以及iphone拍摄的图片是左右翻转的,需要镜像旋转成常规图片
/** * @author luowx on 2018/12/20 0020. */ public class ImageMirrorUtils { /** * 图片镜像翻转 * * @param source 原图片路径 * @param target 翻转后图片输出路径 */ public static void mirrorImage(String source, String target) { File file; BufferedImage image; try { file = new File(source); image = ImageIO.read(file); int width = image.getWidth(); int height = image.getHeight(); for (int j = 0; j < height; j++) { int l = 0, r = width - 1; while (l < r) { int pl = image.getRGB(l, j); int pr = image.getRGB(r, j); image.setRGB(l, j, pr); image.setRGB(r, j, pl); l++; r--; } } file = new File(target); ImageIO.write(image, getSuffix(source), file); } catch (IOException e) { e.printStackTrace(); } } private static String getSuffix(String fileName) { return fileName.substring(fileName.lastIndexOf(SymbolConstants.POINT_SYMBOL) + 1); } }
