Instance Property

depthLimit

The depth limit of the window.

Declaration

var depthLimit: NSWindow.Depth { get set }

Discussion

The value of this property can be examined with the Application Kit functions isPlanar, colorSpaceName, bitsPerSample, and bitsPerPixel. In addition, the NSBestDepth(_:_:_:_:_:) function provides the best depth limit based on a set of parameters.

Setting this property to 0 sets the depth limit to the window’s default depth limit. A depth limit of 0 can be useful for reverting a window object to its initial depth. You can also use one of the explicit bit depths defined in Explicit Window Depth Limits (NSWindow.Depth.twentyfourBitRGB is the default).
