UIImageColors Objects
UIImageColors is struct that contains four different UIColor (or NSColor on macOS) variables.
public struct UIImageColors {
public var background: UIColor!
public var primary: UIColor!
public var secondary: UIColor!
public var detail: UIColor!
}
UIImageColorsQuality is a enum with four different qualities. The qualities refer to how much the original image is scaled down. Lowest implies smaller size and faster performance at the cost of quality colors. High implies larger size with slower performance with good colors. Highest implies no downscaling and very good colors, but it is very slow.
The default is set to high.
public enum UIImageColorsQuality: CGFloat {
case lowest = 50 // 50px
case low = 100 // 100px
case high = 250 // 250px
case highest = 0 // No scale
}
