Java程序为身份证照片添加马赛克

一、创建枚举类型

package com.chuangtu;/*** 比例枚举：此枚举是计算出的各个位置在身份证上的比例信息*/
public enum ProportioEnum {//身份证号idNumber(0.5416666666666667, 0.0805467372134039, 0.3157894736842105, 0.8055784832451499),//姓名name(0.2460850111856823, 0.0986524822695035, 0.1733780760626398, 0.104113475177305),//性别gender(0.0503355704697987, 0.0797872340425532, 0.1733780760626398, 0.2446808510638298),//民族national(0.0503355704697987, 0.0797872340425532,0.3713646532438479, 0.2446808510638298),//生日birthday(0.3557046979865772, 0.0797872340425532,0.1733780760626398,0.3687943262411348),//地址address(0.421834451901566, 0.2482269503546099, 0.1733780760626398, 0.4893617021276596),//面部face(0,0,0,0);ProportioEnum(double targetWith , double targetHeight, double iocationWith, double iocationHeight) {this.targetWith = targetWith;this.targetHeight = targetHeight;this.iocationWith = iocationWith;this.iocationHeight = iocationHeight;}private double targetWith;private double targetHeight;private double iocationWith;private double iocationHeight;/*** 获取目标对象的宽度比* @return*/public double getTargetWith(){return targetWith;}/*** 获取目标对象的高度比* @return*/public double getTargetHeight(){return targetHeight;}/*** 获取位置坐标的宽度比* @return*/public double getIocationWith(){return iocationWith;}/*** 获取位置坐标的高度比* @return*/public double getIocationHeight(){return iocationHeight;}
}
