visual-qr-code

可以创建出设置了虚拟背景图片的二维码,设置的背景图片或logo并不是只是在二维码中心,背景图片和logo都是半透明的,让二维码更好看

一、使用示例(详细情况源码中的测试用例)

示例1:

测试代码
@Test
public void testPOSITIONRECTANGLE() {
    String url = "http://blog.csdn.net/weixin_41279060/article/details/78961532";
    try {
        VisualQRCode.createQRCode(url, 
            "./img/lg-logo.jpg", 
            outPutPath + "QRCodePOSITIONRECTANGLE.png", 
            'H', 
            new Color(2, 85, 43), 
            null, 
            null, 
            null, 
            true,
            VisualQRCode.POSITION_DETECTION_SHAPE_MODEL_RECTANGLE, 
            VisualQRCode.FILL_SHAPE_MODEL_RECTANGLE);
    } catch (IOException e) {
	e.printStackTrace();
    }
}
生成的二维码效果(方形码眼,方形小点):

输入图片说明

示例2:

测试代码
@Test
public void testFILLCIRCLE() {
    String url = "http://blog.csdn.net/weixin_41279060/article/details/78961532";
    try {
        VisualQRCode.createQRCode(url, 
            "./img/lg-logo.jpg", 
            outPutPath + "FILLCIRCLE.png",
            'H', 
            new Color(2, 85, 43), 
            null, 
            null, 
            null, 
            true,
            VisualQRCode.POSITION_DETECTION_SHAPE_MODEL_ROUND_RECTANGLE, 
            VisualQRCode.FILL_SHAPE_MODEL_CIRCLE);
    } catch (IOException e) {
        e.printStackTrace();
    }
}
生成的二维码效果(方圆形码眼,圆形小点):

输入图片说明

示例3:

测试代码
@Test
public void testLARGEIMG(){
    String url = "http://blog.csdn.net/weixin_41279060/article/details/78961532";
    try {
        VisualQRCode.createQRCode(url,
            "./img/xmyrz.jpg", 
            outPutPath+"LARGEIMG.png", 
            'H', 
            new Color(170, 24, 67), 
            800, 
            420, 
            200, 
            false,
            VisualQRCode.POSITION_DETECTION_SHAPE_MODEL_ROUND_RECTANGLE, 
            VisualQRCode.FILL_SHAPE_MODEL_RECTANGLE);
    } catch (IOException e) {
        e.printStackTrace();
    }
}
生成的二维码效果(方圆形码眼,方形小点,设置了初始位置,没有把二维码设置成图片大小):

二、API使用介绍

创建方法:

public static void createQRCode(String content, String bgPath, String outPath, char Level, Color DF, Integer startX, Integer startY, Integer QRCodeWidth, Boolean isDeformation, Integer fillPositionDetectionShapeModel, Integer fillShapeModel) throws IOException

参数说明:

1、content 二维码内容、网址,必需
2、bgPath 背景图片路径,必需
3、outPath 二维码输出路径,必需
4、Level 二维码容错等级,必需
  可选:"L"、"M"、"Q"、"H"
    L水平 7%的字码可被修正
    M水平 15%的字码可被修正
    Q水平 25%的字码可被修正
    H水平 30%的字码可被修正
5、DF 二维码颜色,必需
startX 二维码X轴起点,非必须,默认为图片的左上角
startY 二维码Y轴起点,非必须,默认为图片的左上角
QRCodeWidth 二维码的宽度,非必须,默认为背景图最小边
  二维码的起始X/Y加上QRCodeWidth<=图片的宽/高
6、isDeformation 是否把背景图变成方形,非必须,默认为false不改变图片形状
7、fillPositionDetectionShapeModel 二维码四个大码眼的形状,目前只支持方形和圆方形
  可选:
    POSITION_DETECTION_SHAPE_MODEL_RECTANGLE
    POSITION_DETECTION_SHAPE_MODEL_ROUND_RECTANGLE
8、fillShapeModel 二维码点的形状,目前只支持方形和圆形
  可选:
    FILL_SHAPE_MODEL_RECTANGLE
    FILL_SHAPE_MODEL_CIRCLE

三、使用说明

下载发行版本的jar包,引用,然后使用VisualQRCode.createQRCode创建二维码即可。

声明:

该二维码应用使用了http://www.swetake.com/qrcode 网站上提供的API
