Halcon学习之仿射变换2

//序列化一个均匀2D转换矩阵,将序列化矩阵，以二进制方式写入文件中
HSerializedItem item = hommat2d_scale.SerializeHomMat2d();
HFile file("affine.hobj", "output_binary");
item.FwriteSerializedItem(file);
HHomMat2D temp;
temp.DeserializeHomMat2d(item);//对已经序列化的变换矩阵进行反序列化处理，重新还原成变换矩阵
result_image = image.AffineTransImage(temp, "constant", "true");//进行仿射变换
image.DispColor(w);
w.Click();
w.ClearWindow();
result_image.DispColor(w);
w.Click();

//对两个仿射变换矩阵执行相乘操作
HHomMat2D multiply = hommat2d.HomMat2dCompose(hommat2d_scale);
result_image = image.AffineTransImage(multiply, "constant", "true");//进行仿射变换
image.DispColor(w);
w.Click();
w.ClearWindow();
result_image.DispColor(w);
w.Click();

//计算2D转化矩阵的决定因子
double determinant = hommat2d_scale.HomMat2dDeterminant();
cout << determinant << endl;

cout << "7.转化一个仿射变换矩阵" << endl;
//转化一个仿射变换矩阵
HHomMat2D invert = hommat2d_scale.HomMat2dInvert();
result_image = image.AffineTransImage(invert, "constant", "true");//进行仿射变换
image.DispColor(w);
w.Click();
w.ClearWindow();
