Sets the rendering intent in the current graphics state.
Declaration
func setRenderingIntent(_ intent: CGColorRenderingIntent)Parameters
- intent:
A rendering intent constant—Defaultintent, Absolutecolorimetric, Relativecolorimetric, Perceptual, or Saturation. For a discussion of these constants, see Cgcolorspace.
Discussion
The rendering intent specifies how to handle colors that are not located within the gamut of the destination color space of a graphics context. If you do not explicitly set the rendering intent, Core Graphics uses perceptual rendering intent when drawing sampled images and relative colorimetric rendering intent for all other drawing.
