# getGlyphs(in:glyphs:properties:characterIndexes:bidiLevels:) Fills a passed-in buffer with a sequence of glyphs. ``` func getGlyphs(in glyphRange: NSRange, glyphs glyphBuffer: UnsafeMutablePointer?, properties props: UnsafeMutablePointer?, characterIndexes charIndexBuffer: UnsafeMutablePointer?, bidiLevels bidiLevelBuffer: UnsafeMutablePointer?) -> Int ``` ## Parameters `glyphRange` The range of glyphs to fill in. `glyphBuffer` On output, the sequence of glyphs in the given glyph range. `props` If not `NULL`, on output, the glyph properties corresponding to the filled-in glyphs. `charIndexBuffer` If not `NULL`, on output, the indexes of the original characters corresponding to the given glyph range. Note that a glyph at index 1 is not necessarily mapped to the character at index 1, since a glyph may be for a ligature or accent. `bidiLevelBuffer` If not `NULL`, on output, the direction of each glyph for bidirectional text. The values range from 0 to 61 as defined by Unicode Standard Annex #9. An even value means the glyph goes left-to-right, and an odd value means the glyph goes right-to-left. ## Return Value The number of glyphs returned in `glyphBuffer`. ## Discussion Each pointer passed in should either be `NULL` or else point to sufficient memory to hold `glyphRange.length` elements. --- Copyright © 2026 Apple Inc.
