An introduction to the width tool, deformation tool and lasso tool

一、宽度工具

（1）新建舞台

（2）宽度工具

【宽度工具】快捷键是U.（注意英文输入法）

If the toolbar does not have it, find it here：

We can drag it to the sidebar,方便使用.

（3）作用

【宽度工具】有什么作用呢？

①画一个圆

我们用【椭圆工具】,按Shift键画一个正圆,and fill it with blue.

②拉伸

用【宽度工具】Click on this circle边缘线and stretch outwards.（When the small plus sign appears under the mouse）

可以看到,The edges vary from small to large.

Then we delete the middle one（直接鼠标点击,按Delete键即可）.

This can do some graphic creativity or something.

Unwanted parts can also be deleted.

For example, don't want a small piece on the right,就可以用【选择工具】选中它.

然后按Delete键删除.

可以看到,The edges are automatically stitched.

（4）Line fill stretch

除了上述这种方法,The edge can be changed from small to large.

还有什么办法呢？

①First draw a straight line

用【线条工具】画一条直线.

Change its size to 3.

get a line.

Such lines can only be made“弯曲”,The width cannot be adjusted.

②“修改”–>“形状”–>“Convert lines to fills”.

记得要用【选择工具】Select this line and proceed！

③拉伸

Then we can click on the edge of the line,stretched it.

可以自行调节.

For example, here I stretched one：

（5）区别

Here are drawn and used with lines【宽度工具】Pull out the lines,有什么区别呢？

The left is also equivalent to a line,Only twist and change position,不灵活.

The right side can be changed in size,The same can be done for twist and position changes,较为灵活.

二、任意变形工具

（1）介绍

【任意变形工具】快捷键是Q.（英文输入法）

有什么用呢？

先来用【矩形工具】画一个矩形.

然后用【任意变形工具】frame it.

可以看到,Much better on the rectangle黑色的点.

这些点是控制点.

（2）改变大小

Drag the points,when the mouse becomes Single and double arrows的时候,The size of the rectangle can be changed.

Single and double arrows：

按住Shiftkey to proceed等比例缩放.

（3）Change the tilt direction

Put the mouse on the edge,鼠标变成Double single arrow的时候,You can change the tilt direction of the rectangle.

Double single arrow：

中心点不变,Move the four corners.

When controlling the upper and lower edges,矩形是“左右移动”.

When controlling the left and right edges,矩形是“上下移动”.

（4）水平翻转

将右边（左边）的点,Push hard to the left（右边）拉到底,The rectangle will flip over.

这里为了方便演示,First add a color block to the right of the rectangle（Draw a red rectangle）.

然后用【任意变形工具】Frame the entire rectangle.

Then drag the point on the right to the left,The rectangle will flip horizontally.

或者用【选择工具】Select the entire rectangle,然后：“修改”–>“变形”–>“水平翻转”.

The rectangle can also be flipped horizontally.

（5）垂直翻转

将上边（下边）的点,Push down hard（上边）拉到底,The rectangle will flip over.

这里为了方便演示,First add a color block below the rectangle（Draw a red line）.

然后用【任意变形工具】Frame the entire rectangle.

Then drag the bottom right point to the top,The rectangle will flip vertically.

或者用【选择工具】Select the entire rectangle,然后：“修改”–>“变形”–>“垂直翻转”.

It is also possible to flip the rectangle vertically.

三、套索工具

（1）介绍

【套索工具】的快捷键是L.

（2）作用

有什么用呢？

先来用【矩形工具】画一个矩形.

然后用【套索工具】Select a box to select a place.

This is framed,可以用【选择工具】拿出来.

用【套索工具】Some pictures can be dug out,The part we want.

But the lasso tool is purely manual lasso,Inevitably crooked,不好操作.

（3）多边形工具

This is where the second tool is used：【多边形工具】.

This tool is smoother than the previous one,可以自己去试一下.

But it's not very good either,学过PSshould know a lot of cutout methods.这里就不过多介绍了.

写在最后：

本节比较简单,也很好掌握.

Must be practical,Otherwise there is no muscle memory,It will still not be used by then.

If only use it for animation,I have an example in the first section,It will be introduced in detail later.

在此之前,Know the basic operation first,Otherwise, you won't know what will happen,不好搞啊.

好啦,希望文章对你有帮助,有缘再见~
