*生成矩形，在些矩形区域内进行浏览量，rectangle为生成的矩形变量，ROW COLUMN为矩形中心的行列坐标
*Phi为矩形的倾斜角，Length1, Length2为矩形的半宽，半高。
gen_rectangle2 (Rectangle, Row, Column, Phi, Length1, Length2)
*row column为测量矩形的直剖布线中心点的行列坐标，PHI为直剖面线的方向，可以结合测量矩形
*的图来理解，也就是这条直线的倾斜角度，以水平向右为起始边，逆时针方向为正，反之则反。
*Length1, Length2为矩形的半宽半高，Width, Height为前面图像的高度宽度。
*'nearest_neighbor'表示采用近邻插值算法。为函数输入的测量矩形的句柄。

*循环对每一引脚进行测量
for i := 1 to n by 1
*此函数在前面生成的矩形范围内进行测量。Image为输入图像，MeasureHandle为前面生成的矩形句柄，1.5为
*高斯光滑系数，对应测量助手的那个平滑系数，30为最小边缘幅度，对应助手电波边缘幅度;
*negativege表示找的是负的边缘，也就是由这到暗的边缘对，ALL表示选择全部边缘对
*rowedgefirst，ColumnEdgeFirst表示边缘对中第一条边缘的中心行列坐标。第一条的定义是从测量方向起点开始
*AmplitudeFirst边缘对第一个边缘振幅，也就是灰度值。RowEdgeSecond, ColumnEdgeSecond
*表示边缘对中第二条边缘的中心行列坐标，AmplitudeSecond边缘对第二个边缘振幅
* PinWidth边缘对宽度； PinDistance相邻连续两边缘对的距离。
*此函数的参数都是基于亚像素计算，也就是像素级别是浮点型。
