glyph(at:isValidIndex:)

Declaration

func glyph(at glyphIndex: Int, isValidIndex: UnsafeMutablePointer<ObjCBool>?) -> CGGlyph

Parameters

• glyphIndex:

  The index of the glyph to be returned.

• isValidIndex:

  If not NULL, on output, True if the requested index is in range; otherwise False.

Return Value

The glyph at the requested index, or NSNullGlyph if the requested index is out of the range { 0, numberOfGlyphs }.

Discussion

If noncontiguous layout is not enabled, this method causes generation of all glyphs up to and including glyphIndex.
