Example

The following script replaces the properties of CRect R with its union with another CRect:

R = new_rect()

-- create a CRect object

R:Set(100,200,300,600)

 

R2 = new_rect()

-- create another CRect object

R2:Set(-100,250,200,800)

 

R:Union(R2)

-- updates R, does not change R2

Printf("%lg:%lg, %lg:%lg\n", R:Get())

-- result: -100:250, 200:800.
