Java 图片合并类详解编程语言

public BufferedImage marge(String first, String last, boolean isVertical) { BufferedImage one = this.readImage(first); BufferedImage two = this.readImage(last); if (isVertical) { return this.mergeTwoImageByVertical(one, two); } else { return this.mergeTwoImageByHorizontal(one, two); public void saveImage(String savePath, BufferedImage image) { try { File file = new File(savePath); ImageIO.write(image, "jpg", file);// 写图片 } catch (IOException ex) { ex.printStackTrace(); private BufferedImage mergeTwoImageByVertical(BufferedImage one, BufferedImage two) { int width = this.getWidth(one); int height = this.getHeight(one); int[] oneRPG = this.readImageRPG(one); int[] twoRPG = this.readImageRPG(two); BufferedImage result = new BufferedImage(width, height * 2, BufferedImage.TYPE_INT_RGB); result.setRGB(0, 0, width, height, oneRPG, 0, width); result.setRGB(0, height, width, height, twoRPG, 0, width); return result; private BufferedImage mergeTwoImageByHorizontal(BufferedImage one, BufferedImage two) { int width = this.getWidth(one); int height = this.getHeight(one); int[] oneRPG = this.readImageRPG(one); int[] twoRPG = this.readImageRPG(two); BufferedImage result = new BufferedImage(width * 2, height, BufferedImage.TYPE_INT_RGB); result.setRGB(0, 0, width, height, oneRPG, 0, width); result.setRGB(width, 0, width, height, twoRPG, 0, width); return result; private int[] readImageRPG(BufferedImage image) { int width = this.getWidth(image); int height = this.getHeight(image); int[] imageRPG = new int[width * height];// 从图片中读取RGB imageRPG = image.getRGB(0, 0, width, height, imageRPG, 0, width); return imageRPG; private int getWidth(BufferedImage image) { if (image == null) { return 0; return image.getWidth(); private int getHeight(BufferedImage image) { if (image == null) { return 0; return image.getHeight(); private BufferedImage readImage(String path) { try { File file = new File(path); return ImageIO.read(file); } catch (IOException ex) { ex.printStackTrace(); return null; }
