The format

• The translation(平移) matrix:

  • T = [1 0 0; 0 1 0; tx ty 1]

• The zoom matrix:

  • S = [s 0 0; 0 s 0; 0 0 1]

• The roration matrix:

  • R = [cos() sin() 0; -sin() cos() 0; 0 0 1]

Symbol description

• tx for the x component of displacement

• ty for the y component of displacement

• s for both the x and y component of zoom

• cos(),sin(), the parameter of which is theta, the rotate angle
