[`func getGlyphs(in: NSRange, glyphs: UnsafeMutablePointer?, characterIndexes: UnsafeMutablePointer?, glyphInscriptions: UnsafeMutablePointer?, elasticBits: UnsafeMutablePointer?, bidiLevels: UnsafeMutablePointer?) -> Int`](/documentation/AppKit/NSLayoutManager/getGlyphs(in:glyphs:characterIndexes:glyphInscriptions:elasticBits:bidiLevels:)) Returns the glyphs and information needed to perform layout for the given glyph range. [`func deleteGlyphs(in: NSRange)`](/documentation/AppKit/NSLayoutManager/deleteGlyphs(in:)) Deletes the glyphs in the given range from the receiver’s glyph store. [`func setCharacterIndex(Int, forGlyphAt: Int)`](/documentation/AppKit/NSLayoutManager/setCharacterIndex(_:forGlyphAt:)) Sets the index of the character corresponding to the glyph at the given glyph index. [`func intAttribute(Int, forGlyphAt: Int) -> Int`](/documentation/AppKit/NSLayoutManager/intAttribute(_:forGlyphAt:)) Returns the value of the attribute identified by the given attribute tag for the glyph at the given index. [`func setIntAttribute(Int, value: Int, forGlyphAt: Int)`](/documentation/AppKit/NSLayoutManager/setIntAttribute(_:value:forGlyphAt:)) Sets a custom attribute value for a given glyph. [`func setLocations(NSPointArray, startingGlyphIndexes: UnsafeMutablePointer, count: Int, forGlyphRange: NSRange)`](/documentation/AppKit/NSLayoutManager/setLocations(_:startingGlyphIndexes:count:forGlyphRange:)) Sets locations for many glyph ranges at once. [`func rectArray(forCharacterRange: NSRange, withinSelectedCharacterRange: NSRange, in: NSTextContainer, rectCount: UnsafeMutablePointer) -> NSRectArray?`](/documentation/AppKit/NSLayoutManager/rectArray(forCharacterRange:withinSelectedCharacterRange:in:rectCount:)) Returns an array of rectangles and, by reference, the number of such rectangles, that define the region in the given container enclosing the given character range. [`func rectArray(forGlyphRange: NSRange, withinSelectedGlyphRange: NSRange, in: NSTextContainer, rectCount: UnsafeMutablePointer) -> NSRectArray?`](/documentation/AppKit/NSLayoutManager/rectArray(forGlyphRange:withinSelectedGlyphRange:in:rectCount:)) Returns an array of rectangles and, by reference, the number of such rectangles, that define the region in the given container enclosing the given glyph range. [`func substituteFont(for: NSFont) -> NSFont`](/documentation/AppKit/NSLayoutManager/substituteFont(for:)) Replaces the specified font with a suitable screen font if one is available. [`- (void) showPackedGlyphs:(char *) glyphs length:(NSUInteger) glyphLen glyphRange:(NSRange) glyphRange atPoint:(NSPoint) point font:(NSFont *) font color:(NSColor *) color printingAdjustment:(NSSize) printingAdjustment;`](/documentation/AppKit/NSLayoutManager/showPackedGlyphs:length:glyphRange:atPoint:font:color:printingAdjustment:) Draws a range of glyphs. ### Properties [`var hyphenationFactor: Float`](/documentation/AppKit/NSLayoutManager/hyphenationFactor) The threshold controlling when hyphenation is done.
