需要引用的主键：
1.using PdfSharp;

string png1 = Application.StartupPath + @"\aramexConfig\Png\top.jpg";

string labelPath = aramexShippmentMap["labelPath"].ToString();
string labelName = aramexShippmentMap["labelName"].ToString();
if (File.Exists(labelPath+ labelName+ ".JPG"))
{//文件存在就删除
File.Delete(labelPath + labelName + ".JPG");
}

int margin_top_bottom = 80;//上下边距（这个高度尽量不动，可以去除水印）
//1. 定义文档对象

// 设置纸张大小
page.Size = PageSize.A4;
