iOS 绘图: 图片缩放、叠加、裁剪，线性渐变，径向渐变，PDF 转图片，图片转 PDF ...

Requirements / 使用条件

iOS 11.0+
Xcode 12.2+
Swift 5.0+

Installation / 安装

CocoaPods

pod 'ImageCG'

Manually / 手动安装

If you prefer not to use either of the aforementioned dependency managers, you can integrate ImageCG into your project manually.

如果您不喜欢以上管理依赖库的方式，则可以手动将 ImageCG 集成到项目中。

Usage / 使用

UIColor to UIImage

let image = UIColor.red.icg.image(CGSize(width: 200, height: 100))

UIImage to UIColor

let color = myImage.icg.color

UIImage zoom

let newImage = myImage.icg.zoom(to: CGSize(width: 200, height: 100))

UIImage clip

let newImage = myImage.icg.clip(in: CGRect(origin: .init(x: 10, y: 30), size: .init(width: 200, height: 300)))

PDF to UIImage

let pdfPath: String = "read/to/path/my.pdf"
let images = UIImage.icg.readPDF(from: pdfPath, isJoin: false)

UIImage to PDF

let myImage: UIImage = UIImage()
myImage.icg.savedPDF(to: NSHomeDirectory() + "saved/to/path/my.pdf")

UIImage add UIImage 在图片上添加图片

let baseImage = UIImage(named: "BaseImageName")!
let logoImage = UIImage(named: "LogoImageName")!
let image = baseImage.icg.add(logoImage)

Linear Gradient 线性渐变

let colors = [UIColor.blue, UIColor.red, UIColor.yellow, ...]
let image = colors.icg.linearGradient(CGSize(width: 200, height: 100), 
direction: .diagonally)

Radial Gradient 径向渐变

let colors = [UIColor.blue, UIColor.red, UIColor.yellow, ...]
let image = colors.icg.radialGradient(CGSize(width: 200, height: 100), 
direction: .diagonally)
