# `GSLayer scaleToFullHeight:bounds:`

*Instance Method*

Scales the layer contents to the vertical span of the glyph metrics.

## Declaration

```swift
func scale(toFullHeight layerMetrics: GSGlyphMetrics, bounds: NSRect)
```

```objc
- (void) scaleToFullHeight:(GSGlyphMetrics) layerMetrics bounds:(NSRect) bounds;
```

```python
scaleToFullHeight_bounds_(layerMetrics: GSGlyphMetrics, bounds: NSRect)
```

## Parameters

- `layerMetrics` — The target vertical metrics.
- `bounds` — The source bounds to use when the layer has no enclosing rectangular path.

## Discussion

A rectangular path enclosing the other content is treated as the source bounds and removed.
