# `GSPointOffsetFromLine`

*Function*

Like `GSPointOnLine`, but with the returned point offset by a certain amount onto a parallel line. So, more like the inverse of `GSNearestPointOnLine`.

## Declaration

```swift
func GSPointOffsetFromLine(_ p0: NSPoint, _ p1: NSPoint, _ t: CGFloat, _ offset: CGFloat) -> NSPoint
```

```objc
NSPoint GSPointOffsetFromLine(NSPoint p0, NSPoint p1, CGFloat t, CGFloat offset);
```

```python
GSPointOffsetFromLine(p0: NSPoint, p1: NSPoint, t: float, offset: float) -> NSPoint
```

## Parameters

- `offset` — Offset to the right of the line if positive or to the left of the line if negative.
