Analysis on the influence of the operation sequence of Photoshop paths on path combinations-PS tutorial

In the last lesson, we talked about the operation mode of the Photoshop path (refer to "using the Photoshop path as a" super building block "combination model"). through the operation, we can add another shape to a shape, they can also subtract or perform cross operations to get a new shape. This article describes the effect of the operation sequence of the Photoshop path on the path combination result. In the last lesson, we talked about the operation mode of the Photoshop path (refer to "using the Photoshop path as a" super building block "combination model"). through the operation, we can add another shape to a shape, they can also subtract or perform cross operations to get a new shape. This article describes the effect of the operation sequence of the Photoshop path on the path combination result. We spoke about the last lesson. Photoshop Path calculation mode(Refer to "using Photoshop paths as a" super building block "combination model"). through computation, we can add another shape to a shape, or subtract or crossover them, get a new shape. In this article, we will talk about PhotoshopThe effect of the path operation sequence on the path combination result.
Give friends a small question first: a friend fights the landlord, a first goes out, there is a big ghost in his hand, a 7, a 3; B later, there are two 2 in his hand. Q: How can I win a card.
Friends who often play cards will say that they must first take a 3 picture and use the big ghost to crack the opponent's 2 picture!
Yes, this is a small example that determines the order of playing cards. Similarly, we can apply this thinking to path operations, using the same path and the same operation mode, while different operation sequences get different calculation results.
It is a part of a bear's portrait. the leftmost part is the path involved in the calculation, and the result is obtained by the sequential operation after the first addition and subtraction in the middle, the right side is the result of the sequential operation obtained by first subtraction and then addition. You can see the obvious differences between them in the ear.
Why are these differences? This is because in the process of first adding and then subtracting, we first combine the shape and then cut off the internal area to form the effect of connecting the ears to the head. In the process of first subtraction and then addition, we first cut off the internal area of the ear. Then, when we added the header, some of the regions that were cut out were added back, so we got different calculation results.
