# setAttachmentSize(_:forGlyphRange:)

Sets the size to use when drawing a glyph that represents an attachment.

```
func setAttachmentSize(_ attachmentSize: CGSize, forGlyphRange glyphRange: NSRange)
```

## Parameters

`attachmentSize`

The glyph size to set.

`glyphRange`

The attachment glyph’s position in the glyph stream.

## Discussion

For a glyph corresponding to an attachment, this method should be called to set the size for the attachment cell to occupy. The glyph’s value should be <doc://com.apple.documentation/documentation/AppKit/NSControlGlyph>.

This method is used by the layout mechanism and should be invoked only during typesetting, in almost all cases only by the typesetter. For example, a custom typesetter might invoke it.

## See Also

[`func attachmentSize(forGlyphAt: Int) -> CGSize`](/documentation/UIKit/NSLayoutManager/attachmentSize(forGlyphAt:))

Returns the size of the attachment glyph at the specified index.
