# `GSIntersectCubicLine`

*Function*

> **Deprecated**

Finds all intersections between a curve and a line.

## Declaration

```swift
func GSIntersectCubicLine(_ p1: NSPoint, _ p2: NSPoint, _ p3: NSPoint, _ p4: NSPoint, _ a1: NSPoint, _ a2: NSPoint) -> [Any]?
```

```objc
NSArray *GSIntersectCubicLine(NSPoint p1, NSPoint p2, NSPoint p3, NSPoint p4, NSPoint a1, NSPoint a2);
```

```python
GSIntersectCubicLine(p1: NSPoint, p2: NSPoint, p3: NSPoint, p4: NSPoint, a1: NSPoint, a2: NSPoint) -> list
```

## Parameters

- `p1` — Start point of the curve.
- `p2` — First offcurve point of the curve.
- `p3` — Second offcurve point of the curve.
- `p4` — End point of the curve.
- `a1` — First point of the line.
- `a2` — Second point of the line.

## Return Value

An NSArray of point values for all intersections.
