# attachmentBounds(for:proposedLineFragment:glyphPosition:characterIndex:)

Returns the layout bounds of the text attachment to the layout manager.

## Declaration

```swift
func attachmentBounds(for textContainer: NSTextContainer?, proposedLineFragment lineFrag: CGRect, glyphPosition position: CGPoint, characterIndex charIndex: Int) -> CGRect
```

## Parameters

- `textContainer`: The text container for the text being laid out.
- `lineFrag`: The line fragment containing the text attachment.
- `position`: The glyph location inside lineFrag which is the origin of the returned bounds rectangle.
- `charIndex`: The character location inside the text storage for the attachment character.

## Return Value

Return Value The bounds rectangle of the text attachment if not CGRectZero; otherwise, the rectangle of the size property of the attachment’s image property.

## Discussion

Discussion Conforming objects can implement more sophisticated logic for negotiating the attachment bounds based on the available container space and proposed line fragment rectangle.
