Java实现图片拼接

Java实现图片拼接

本文实例为大家分享了java实现图片拼接的具体代码，供大家参考，具体内容如下

/**

* 拼接图片（注：图片需长宽一致）

* @param files img1 ，img2

* @param type 1：横向拼接 2：纵向拼接

* @param targetFile 合成新的图片地址

*/

public static void mergeImage(String[] files, int type, String targetFile) {

int len = files.length;

if (len < 1) {

throw new RuntimeException("图片数量小于1");

}

File[] src = new File[len];

BufferedImage[] images = new BufferedImage[len];

int[][] ImageArrays = new int[len][];

for (int i = 0; i < len; i++) {

try {

src[i] = new File(files[i]);

images[i] = ImageIO.read(src[i]);

} catch (Exception e) {

throw new RuntimeException(e);

}

int width = images[i].guMUAUjMLVbetWidth();

int height = images[i].getHeight();

ImageArrays[i] = new int[width * height];

ImageArrays[i] = images[i].getRGB(0, 0, width, height, ImageArrays[i], 0, width);

}

int newHeight = 0;

int newWidth = 0;

for (int i = 0; i < images.length; i++) {

// 横向

if (type == 1) {

newHeight = newHeight > images[i].getHeight() ? uMUAUjMLVbnewHeight : images[i].getHeight();

newWidth += images[i].getWidth();

} else if (type == 2) {// 纵向

newWidth = newWidth > images[i].getWidth() ? newWidth : images[i].getWidth();

newHeight += images[i].getHeight();

}

}

if (type == 1 && newWidth < 1) {

return;

}

if (type == 2 && newHeight < 1) {

return;

}

// 生成新图片

try {

BufferedImage ImageNew = new BufferedImage(newWidth, newHeight, BufferedImage.TYPE_INT_RGB);

int height_i = 0;

int width_i = 0;

for (int i = 0; i < images.length; i++) {

if (type == 1) {

ImageNew.setRGB(width_i, 0, images[i].getWidth(), newHeight, ImageArrays[i], 0,

images[i].getWidth());

width_i += images[i].getWidth();

} else if (type == 2) {

ImageNew.setRGB(0, height_i, newWidth, images[i].getHeight(), ImageArrays[i], 0, newWidth);

height_i += images[i].getHeight();

}

}

//输出想要的图片

ImageIO.write(ImageNew, targetFile.split("\\.")[1], new File(targetFile));

} catch (Exception e) {

throw new RuntimeException(e);

}

}
