#region nopi创建画图
// 通常，利用NPOI画图主要有以下几个步骤：
//1.创建一个Patriarch；
//2.创建一个Anchor，以确定图形的位置；
//3.调用Patriarch创建图形；
//4.设置图形类型(直线，矩形，圆形等)及样式（颜色，粗细等）。
//关于HSSFClientAnchor(dx1, dy1, dx2, dy2, col1, row1, col2, row2)的参数，有必要在这里说明一下：
//dx1：起始单元格的x偏移量，如例子中的255表示直线起始位置距A1单元格左侧的距离；
//dy1：起始单元格的y偏移量，如例子中的125表示直线起始位置距A1单元格上侧的距离；
//dx2：终止单元格的x偏移量，如例子中的1023表示直线起始位置距C3单元格左侧的距离；
//dy2：终止单元格的y偏移量，如例子中的150表示直线起始位置距C3单元格上侧的距离；
//col1：起始单元格列序号，从0开始计算；
//row1：起始单元格行序号，从0开始计算，如例子中col1 = 0,row1 = 0就表示起始单元格为A1；
//col2：终止单元格列序号，从0开始计算；
//row2：终止单元格行序号，从0开始计算，如例子中col2 = 2,row2 = 2就表示起始单元格为C3；
