# Strokes

Strokes are the final rendered lines. Yet you can tweak them, for example, by removing the ones longer/shorter than some threshold, chaining lines into a single stroke or breaking a stroke into several ones based on angles, dashed pattern, etc.

- Caps
You can choose between three types of line caps:

- Butt
Flat cap, exactly at the point the line ends.

- Round
A half circle centered on the end point of the line.

- Square
A square centered on the end point of the line (hence, like the circle, the drawn end of the line is slightly extended compared to its computed value).

## Chaining

By default all retrieved lines from the line set are chained together. There are two basic chaining methods:

- Method
- Plain
The default chaining method; it creates simple chains.

- Sketchy
This chaining option allows for generating chains of feature edges with sketchy multiple strokes. Basically, it generates

*Round*strokes instead of a single one. It is only really useful if you use some random-driven modifiers in the line style!- Rounds
It specifies the number of rounds in sketchy strokes.

- Same Object
If true, only feature edges of the same object are joined.

Chaining can also be turned off to render each line separately, which can be useful for line styles which depend on accurate representation of the line set.

## Splitting

You can split up chains of Freestyle lines by enabling one of the following:

- Min/Max 2D Angle
Splits chains of feature edges when they make a 2D angle above (or below) a minimum (or maximum) threshold.

- 2D Length
Splits chains when they are longer than the given value.

- Material Boundary
Splits chains of feature edges if they cross from one material to another.

### Split Pattern

Splits the chains using the given dashed pattern (see also Dashed Line).

- Dash 1, 2, 3
Length of the specified dash for splitting.

- Gap 1, 2, 3
Length of the specified gap for splitting.

## Sorting

You can sort the order of your strokes, allowing the lines to stack in the order given.

- Sort Key
A sort key is used to determine the stacking order of lines.

- Distance from Camera
Lines closer to the camera lie on top of further lines.

- 2D Length
Longer lines lie on top of shorter lines.

- Projected X/Y
Sort by the projected X or Y value in the image coordinate system.

- Integration Type
Use in tandem with the Sort Key to determine the range for sorting. Since the distance of a line from the camera may vary over vertices, this option computes the sort key for a line from the values computed at individual vertices. The value computed for the line is:

- Mean
The mean of the values obtained for the vertices.

- Min
The minimum of the values obtained for the vertices.

- Max
The maximum of the values obtained for the vertices.

- First
The value obtained for the first vertex.

- Last
The value obtained for the last vertex.

- Sort Order
With the given result you can choose to «Reverse» the sort order.

## Selección

You can also choose to only render selected chains.

- Min/Max 2D Length
Chains longer and/or shorter than

*2D Length*.

- Chain Count
Allows the selection of first N chains.

## Dashed Line

By enabling the *Dashed Line* checkbox,
you can specify three pairs of dash and gap lengths.
Dash values define the lengths of dash strokes,
while gap values specify intervals between two dashes.

If a zero gap is specified, then the corresponding dash is ignored even if it has a nonzero value.

Dashes are treated as separate strokes, meaning that you can apply line caps, as well as color, alpha and thickness modifiers.

- Dash 1, 2, 3
Length of the specified dash for dashed lines.

- Gap 1, 2, 3
Length of the specified gap for dashed lines.
