# boundsRect(for:at:effectiveRange:)

Returns the bounding rectangle for the specified text block and glyph.

```
func boundsRect(for block: NSTextBlock, at glyphIndex: Int, effectiveRange effectiveGlyphRange: NSRangePointer?) -> NSRect
```

## Parameters

`block`

The text block whose bounding rectangle is returned.

`glyphIndex`

Index of the glyph.

`effectiveGlyphRange`

If not `NULL`, on output, the range for all glyphs in the text block.

## Return Value

The bounding rectangle of the text block, or `NSZeroRect` if no rectangle has been set for the specified block since the last invalidation.

## Discussion

This method causes glyph generation but not layout. Block layout rectangles and bounds rectangles are always in container coordinates.
