NSBitmapImageRep.PropertyKey
Constants that identify bitmap image representation properties.
Declaration
struct PropertyKeyDiscussion
Use these constants with representationOfImageReps(in:using:properties:), representation(using:properties:), setPixel(_:atX:y:), and value(forProperty:).
When using the value(forProperty:) method to retrieve the the value for any of these keys, be sure to check that the returned value is non-nil before you attempt to use it. A bitmap image representation may return nil for any values that have not yet been set.
