FlexibleImage is implemented with the hope that anyone could easily develop an app that provides features such as Camera Filter and Theme. When you write code in the "Method Chaining" style, the effect is applied in the appropriate order.
You may want to see Examples section first if you'd like to see the actual code.
import UIKit
import FlexibleImage
/// Generate Example
let image1 = UIImage
.circle(
color: UIColor.blue,
size: CGSize(width: 100, height: 100)
)!
.adjust()
.offset(CGPoint(x: 25, y: 0))
.margin(UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5))
.padding(UIEdgeInsets(top: 15, left: 15, bottom: 15, right: 15))
.normal(color: UIColor.white)
.border(color: UIColor.red, lineWidth: 5, radius: 50)
.image()!
.adjust()
.background(color: UIColor.darkGray)
.image()
/// Effect Example
let image2 = UIImage(named: "macaron.jpg")!
.adjust()
.outputSize(CGSize(width: 250, height: 250))
.exclusion(color: UIColor(red: 0, green: 0, blue: 0.352941176, alpha: 1.0))
.linearDodge(color: UIColor(red: 0.125490196, green: 0.058823529, blue: 0.192156863, alpha: 1.0))
.hardMix(color: UIColor(red: 0.3, green: 0.3, blue: 0.3, alpha: 1.0))
.image()
/// Mix Example
let image3 = image2!.adjust()
.append(
image1!.adjust()
.outputSize(CGSize(width: 250, height: 250))
.alpha(0.5)
)
.image()
/// Clipping Example
let image4 = image3!.adjust()
.corner(CornerType(25))
.image()
/// Pipeline
let pipeline = ImagePipeline()
.exclusion(color: UIColor(red: 0, green: 0, blue: 0.352941176, alpha: 1.0))
.linearDodge(color: UIColor(red: 0.125490196, green: 0.058823529, blue: 0.192156863, alpha: 1.0))
let image5 = pipeline.image(image2)
let image6 = pipeline.image(image1)Use CocoaPods command $ pod try FlexibleImage to try Playground!
