Function

CGContextSetAllowsFontSubpixelPositioning

Sets whether or not to allow subpixel positioning for a graphics context.

Declaration

void CGContextSetAllowsFontSubpixelPositioning(CGContextRef c, bool allowsFontSubpixelPositioning);

Parameters

context

A graphics context.

allowsFontSubpixelPositioning

A Boolean value that specifies whether subpixel positioning of glyphs is allowed in the specified context.

Discussion

Sub-pixel positioning is used by the graphics context if it is allowed, enabled, and if the font itself is antialiased when drawn. For information on how to enable subpixel positioning, see the CGContextSetShouldSubpixelPositionFonts function.

This parameter is not part of the graphics state.
