jbase打印完善

上一篇实现了粗略的打印元素绘制协议，并且写了打印示例和导出示例，趁着空隙时间完善一下打印。

首先元素构造函数默认初始化每个字段值

package LIS.Core.Dto;

/**
 * 打印约定元素
 */
public class PrintElement {
    /**
     * 元素类型
     */
    public String PrintType;

    /**
     * X
     */
    public String PrintX;

    /**
     * Y
     */
    public String PrintY;

    /**
     * 字体
     */
    public String PrintFont;

    /**
     * 字体大小
     */
    public String PrintFontSize;

    /**
     * 字体样式
     */
    public String PrintFontStyle;

    /**
     * 长度
     */
    public String PrintLength;

    /**
     * 宽度
     */
    public String PrintWidth;

    /**
     * 高度
     */
    public String PrintHeight;

    /**
     * 文本
     */
    public String PrintText;

    /**
     * 数据字段
     */
    public String DataField;

    /**
     * 特殊标志
     */
    public String PrintFlag;

    /**
     * 停靠
     */
    public String PrintAlignment;

    /**
     * 图片
     */
    public String PrintImageFile;

    /**
     * 颜色
     */
    public String PrintColor;

    /**
     * 旋转角度
     */
    public String Angle;

    /**
     * 垂直显示
     */
    public String IsVShow;

    /**
     * 业务ID
     */
    public String BllID;

    /**
     * 构造
     */
    public PrintElement()
    {
        PrintType="";
        PrintX="10";
        PrintY="10";
        PrintFont="宋体";
        PrintFontSize="10";
        PrintFontStyle="";
        PrintLength="10";
        PrintWidth="20";
        PrintHeight="20";
        PrintText="";
        DataField="";
        PrintFlag="";
        PrintAlignment="";
        PrintImageFile="";
        PrintColor="";
        Angle="0";
        IsVShow="";
        BllID="";
    }
}

加强绘制元素的类型约束和检查，把换页，打印机控制等都实现

package LIS.Core.Util;

     * 打印文本的停靠方向
     */

    }

        ret.DataField = paper;

打印基础就更稳定了，业务只需要按要求控制输出数据就行了，可以结合设计器的保存数据和业务数据组装
