setDrawsOutsideLineFragment(_:forGlyphRange:)

Declaration

func setDrawsOutsideLineFragment(_ flag: Bool, forGlyphRange glyphRange: NSRange)

Parameters

• flag:

  True if the glyphs in glyphRange exceed the bounds of the line fragment in which they are laid out, False otherwise.

• glyphRange:

  The range of the glyphs in question.

Discussion

This can happen when text is set at a fixed line height. For example, if the user specifies a fixed line height of 12 points and sets the font size to 24 points, the glyphs will exceed their layout rectangles.

A subclass can override this method to interact with custom glyph storage.
