JPCrop

Example

Tool class with high imitation of cutting function of little red book app. Juejin Blog

高仿小红书App裁剪功能的工具：
    1.集成类似小红书基本的裁剪功能（自定义裁剪比例 + 360°任意旋转）；
    2.API简单易用；
    3.切换裁剪比例带有动画过渡，不会那么生硬；
    4.可异步可同步裁剪，并且可压缩。

How to use

Is so easy:

Initialization

// 1.Import
import JPCrop

// 2.Initialize
let frame = CGRect(...
let configure = Croper.Configure(image)
let croper = Croper(frame: frame, configure)

// 3.Add to superview, done!
view.insertSubview(croper, at: 0)

Rotate

/**
 * originAngle: Rotation origin angle.
 * There are four origins: 0°/360°, 90°, 180°, 270°
 * The rotatable angle range of each origin angle is: -45° ~ 45°
 */
 
// Rotate (Rotatable angle range: Based on the current origin angle -45° ~ 45°)
croper.rotate(angle)

// Rotate left (originAngle - 90°)
// animated: with animation or not
croper.rotateLeft(animated: true)
        
// Rotate right (originAngle + 90°)
// animated: with animation or not
croper.rotateRight(animated: true)

// Show grid before rotating
// animated: with animation or not
croper.showRotateGrid(animated: true)

// Hide grid after rotating
// animated: with animation or not
croper.hideRotateGrid(animated: true)

Switch the crop width to height ratio

// rotateGridCount: Number of grid in rotation. (ver, hor)
// animated: with animation or not
croper.updateCropWHRatio(3.0 / 4.0, rotateGridCount: (6, 5), animated: true)

Reset

// animated: with animation or not
croper.recover(animated: true)

Crop

let configure = croper.syncConfigure()

// 1.Sync crop
let image = croper.crop() 
cropDone(image, configure)

// 2.Async crop: crop in DispatchQueue.global, result back to DispatchQueue.main 
croper.asyncCrop {
    guard let image = $0 else { return }
    cropDone(image, configure)
}

// PS: You can set the compressionScale to compress the image

More features will be added in the future...
