Instance Method

setShouldSubpixelQuantizeFonts(_:)

Enables or disables subpixel quantization in a graphics context.

Declaration

func setShouldSubpixelQuantizeFonts(_ shouldSubpixelQuantizeFonts: Bool)

Parameters

shouldSubpixelQuantizeFonts

A Boolean value that specifies whether to enable subpixel quantization.

Discussion

When enabled, the graphics context may quantize the subpixel positions of glyphs.

This parameter is part of the graphics state.
