測試

package com.Zxing;

public class Test {
    public static void main(String []args) throws Exception
    {
        String imgPath= "src/Fukang.gif";
        String content = "BEGIN:VCARD\n" + "VERSION:3.0\n" + "N:王雪晴\n" + "EMAIL:[email protected]\n" + "TEL:[phone]\n" + "ADR:河北省石家莊市\n" + "ORG:\n" + "TITLE:\n" + "URL:src/1.jpg\n" + "NOTE:我是一個樂觀可愛的人\n" + "END:VCARD";//內容,src個人主頁
        String logo = "src/1.jpg";
        ZxingUtil zxingUtil = new ZxingUtil();
        zxingUtil.eccodeImt(imgPath,"gif",content,430,430,logo);

    }
