java在圖片上寫入文字-IDNo身份證生成方法

一、IDCardGenerate.java(接口)--//接口的定義,接口裏只包含常量和抽象方法.

public interface IDCardGenerate {
	//public static final String outPath = "D:/gen/idcard.png";
	//public static final String outDir = "D:/gen/";
	public static final String outPath = ".\\idcard.png";//這個是臨時文件名
	public static final String outDir = ".\\";
	public static final String outSuf = ".jpg";
	public static final int canvasWidth = 480;
	public static final int canvasHeight = 320;
	public static final int imgWidth = 270;
	public static final int imgHeigth = 428;
	public static final int xStart = 60;
	public static final int yStart = 85;
	public static final int yStep = 32;
	public static final int xStep = 90;
	public static final int charSpace = 10;
	public static final int paramXStart = 110;
	public static final int nationSpace = 140;
	public static final int monthSpace = 120;
	public static final int daySpace = 60;
	public static final int idNoSpace = 80;
	public static final int charLineSpace = 25;
	
	
	public void paint();
}

 

二、IDCardInfo.java

public class IDCardInfo {
	private String name = "";
	private String sex = "";
	private String nation = "";
	private String bornYear = "";
	private String bornMonth = "";
	private String bornDay = "";
	private String addr = "";
	private String idNo = "";
	private String expDate = "";
	private String issuingAuthority = "";
	private String addr1 = "";
	private String addr2 = "";
	
	
	
	public String getAddr1() {
		addr1 = addr.length() > 11 ? 
				addr.substring(0,11) : "";
		return addr1;
	}
	
	public String getAddr2() {
		addr2 = addr.length() > 11 ? 
				addr.substring(11) : "";
		return addr2;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public String getNation() {
		return nation;
	}
	public void setNation(String nation) {
		this.nation = nation;
	}
	public String getBornYear() {
		return bornYear;
	}
	public void setBornYear(String bornYear) {
		this.bornYear = bornYear;
	}
	public String getBornMonth() {
		return bornMonth;
	}
	public void setBornMonth(String bornMonth) {
		this.bornMonth = bornMonth;
	}
	public String getBornDay() {
		return bornDay;
	}
	public void setBornDay(String bornDay) {
		this.bornDay = bornDay;
	}
	public String getAddr() {
		return addr;
	}
	public void setAddr(String addr) {
		this.addr = addr;
	}
	public String getIdNo() {
		return idNo;
	}
	public void setIdNo(String idNo) {
		this.idNo = idNo;
	}
	public String getExpDate() {
		return expDate;
	}
	public void setExpDate(String expDate) {
		this.expDate = expDate;
	}
	public String getIssuingAuthority() {
		return issuingAuthority;
	}
	public void setIssuingAuthority(String issuingAuthority) {
		this.issuingAuthority = issuingAuthority;
	}
}

	}	
	private Graphics2D getTemplateFront(BufferedImage bi) {//該方法是用來獲取模板樣式

四、TestGenCard.java(程序入口)

public class TestGenCard {
	public static void main(String[] args) {
		IDCardInfo idCard = new IDCardInfo();
		idCard.setName("趙一鵬");
		idCard.setSex("男");
		idCard.setNation("漢");
		idCard.setBornYear("1999");
		idCard.setBornMonth("8");
		idCard.setBornDay("8");
		idCard.setAddr("陝西省渭南市大荔縣黃河鎮黃家溝二組");
		idCard.setIdNo("622426199908080018");
		try {
			IDCardGeneratorFront idCardFront = new IDCardGeneratorFront(idCard);
			idCardFront.paint();
			System.out.println("complete!!!");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

執行方法：進入當前java文件目錄，打開命令窗口，一、執行javac TestGenCard.java進行編譯（若出現亂碼，則執行javac -encoding utf-8 TestGenCard.java），二、java TestGenCard執行java文件運行成功
