ImageLab 生成感兴趣区域，并赋值
Load(Lena.bmp, R, G, B, A);

Point[1][0] = 100;
Point[0][1] = 200;

Point[1][2] = 100;
Point[0][3] = 350;

Point[0][4] = 150;
Point[1][4] = 300;
##生成ROI区域，值为1
MakeROI(Roi,Point,1,spline);
##值为1的ROI区域，像素值设为200
SetROIValue(R, Roi, 1, 200);
Save(1label.bmp, gray, R, G, B, A);//保存了
