# showCGGlyphs(_:positions:count:font:matrix:attributes:in:) Renders the glyphs at the specified positions, using the specified attributes. ``` func showCGGlyphs(_ glyphs: UnsafePointer, positions: UnsafePointer, count glyphCount: Int, font: NSFont, matrix textMatrix: AffineTransform, attributes: [NSAttributedString.Key : Any] = [:], in graphicsContext: NSGraphicsContext) ``` ## Parameters `glyphs` The glyphs to draw; may contain embedded `NULL` bytes. `positions` The positions at which to draw the glyphs in the user space coordinate system. `glyphCount` The number of glyphs. `font` The font applied to the graphics state. This value can be different from the `NSFontAttributeName` value in the `attributes` argument because of various font substitutions that the system automatically executes. `textMatrix` The affine transform mapping the text space coordinate system to the user space coordinate system. The `tx` and `ty` components of `textMatrix` are ignored since Quartz overrides them with the glyph positions. `attributes` A dictionary of glyph attributes. See [Glyph Attributes](/documentation/AppKit/glyph-attributes) for supported keys and values. `graphicsContext` If non-`nil`, `graphicsContext` is already configured according to the text attributes arguments: `font`, `textMatrix`, and `attributes`. ## Discussion `NSLayoutManager` invokes this primitive method unless an override implementation of the deprecated [`showPackedGlyphs:length:glyphRange:atPoint:font:color:printingAdjustment:`](/documentation/AppKit/NSLayoutManager/showPackedGlyphs:length:glyphRange:atPoint:font:color:printingAdjustment:) method exists and this method is not overridden. --- Copyright © 2026 Apple Inc.
