foreword
First attach the official introduction to vector layers for your reference.
Q:
Why is it recommended to draw lines on the [Vector Layer]?
A:
I think the main reason is,
It is convenient for us to [modify] the lines on the way of drawing.
Increase the error tolerance rate when drawing line art.
Use [Zoom Line] to get a preliminary understanding of vector layers
In Clip, any brush that can be used to draw lines can adjust the degree of [anti-aliasing].
So whether or not the edges of your lines have been softened, and how much they are softened, depends on your brush settings.
But if you want to scale or deform the drawn line,
At this time, whether the line is drawn on the vector layer will make a certain difference.
We draw a line on each of the bitmap layer and the vector layer as a demonstration.
Scale both lines at the same time,
You will find that the edge of the line on the right has become blurred,
Line edges on the left are not affected.
This is because the lines drawn on the vector layer are not recorded in the way of recording the lines on the raster layer, which is to record the range of pixels.
The lines on the vector layer are all vector lines recorded by [coordinate points].
The system will first memorize the positions of multiple points, then calculate them into a string of line segments, and finally apply the settings of the brush to the line, so that no matter how the line is scaled, the settings on the line segment will not be affected too much impact.
We can use the operation tool to see the coordinate points that make up the vector line.
And move these points to change the shape of the line.
Of course, we can also use these points to make more changes to the lines,
This is why I would say why you should use a vector layer - for modification.
Use examples to understand functionality
Next I'll use the example,
Introduce some functions that I think are related to vector layers and commonly used in drawing lines.
The original picture of this example, in order to let everyone see the effect of the tool more clearly,
I only used a fixed size brush to paint it when drawing.
So its lines are very rigid at first, with less variation in thickness,
And I will gradually change it to look like the picture below.
┗ Eraser for vector lines
First of all, let's get acquainted with the special eraser for vector lines.
You can find it in the toolbar of the eraser,
In the Tool Properties bar, delete Vector Selection -- To Intersection,
In this way, we can quickly erase the miscellaneous lines by simply rubbing a stroke on the redundant and branched line segments.
We can use this eraser function,
To help sample hair, quickly erase unwanted line segments.

┗ Line Correction
Line Correction -- Correct line width
As the name suggests, it is to change the width of the line.
We're going to use this feature to save the example from the rigid lines.
First, we're going to thin some of the lines that are too thick.
It has two options both to make the lines thinner.
◯ Thinner at specified width
◯Zoom down to the specified multiple
I recommend choosing the following to zoom out to the specified multiple,
Because this option is to thin the line according to the original line [ratio],
And the option above is [Reduce the number of pixels with a fixed value],
This option can easily make the line too thin, and the user needs to adjust the value slowly.
Adjust the value to be more extreme, and compare the two,
Reducing to the specified multiple will not affect the length of the original line segment.
We use this trick,
A few strokes of the hair layer on the example image will thin the overall lines.
Reduce the size of the brush, and continue to adjust other places where the line is too thick.
Adjusted alignment
Let's make persistent efforts and continue to thicken the places where the lines should be thickened.
For the options in bold, it is also recommended to follow [Multiple] below.
Suitable for bold positions,
For example: cheeks, or lines around the body.
Only using the function of [Correct Line Width], do you feel that the line has become more or less beautiful?
Add some more lines, add shadows and trim it,
The line part is done.
┗ Not only the lines drawn by brushes are suitable for vector layers
Basically, as long as it can be drawn on the vector layer, it can be adjusted by using the operation - object.
For example, in graphics tools, line segments, circles, rectangles, etc.
Of course, if the shape is drawn on an ordinary bitmap layer, there is no way to modify its shape.
In this way, we can use graphics to simply decorate the background.

Other Supplements About Vectors
●If you want to change the color of the lines locally, you must change the vector layer into a bitmap layer.
When the line is a vector line, even if you only click one of the control points on the line,
Selecting a new color will also change the color of the entire line segment together.
So at this time, you must convert the vector to a lattice before you can perform local coloring.
Right-click on the layer, you can find the option of [bit matrix layering].
But this operation is irreversible. Once converted to a raster layer, it cannot be converted back to a vector layer.
Therefore, it is recommended to copy the layer first for backup before conversion.
●On the vector layer, it is not possible to fill in with paint buckets or fill in gradient colors.
This serves as a reminder,
If you want to fill in the canvas, but the color can't be poured.
Probably because of the relationship you added to the vector layer.
At this time, just pour the color on the dot matrix layer, and you can continue your coloring work.
postscript
In my concept, as long as you understand the simple principles about vectors,
When you usually adjust the lines, most of the time you don't have to face those dense control points.
(Watching will only confuse your mind)
And I only share the parts that I usually think are commonly used, so the content of the article is not too long.
The official article has a more detailed explanation of other functions. If you want to study related functions in depth, I recommend you to take a look.
