Instance Property


The working color space of the Core Image context.


var workingColorSpace: CGColorSpace? { get }


The working color space determines the color space used when executing filter kernels; Core Image automatically converts to and from the source and destination color spaces of input images and output contexts. You specify a working color space using the workingColorSpace key in the options dictionary when creating a Core Image context.
