Generally, there are two imaging methods.
Only by distinguishing these two.
Flexible method of image transformation.
When using image transformation to make an image, it is advocated to translate first and then expand and contract, but it often happens that expand and contract first and then translate.
Anyway,
Deformation, please remember, every deformation is always in the letter.
x
Generally speaking, it depends on the image transformation.
How much the "variable" has changed, not
What is the "angle change"
Path 1: Translation transformation first and then periodic transformation.
