Usage

1. Import the module in your Swift file:

import JDrawView

2. Create and add a JDrawView to your view hierarchy:

let drawView = JDrawView(frame: view.bounds)
view.addSubview(drawView)

3. Customize the drawing:

// Set line color
drawView.setDrawColor(color: .red)

// Set line width
drawView.setDrawWidth(width: 5.0)

// Add dash lines
drawView.setHorizonDashLine(set: true)
drawView.setVerticalDashLine(set: true)

4. Get the drawing as an image:

let image = drawView.asImage()

5. Clear the drawing:

drawView.clearDrawing()

Example

import UIKit
import JDrawView

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let drawView = JDrawView()
        view.addSubview(drawView)

        drawView.translatesAutoresizingMaskIntoConstraints = false
        
        NSLayoutConstraint.activate([
            drawView.topAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.topAnchor, constant: 20),
            drawView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor, constant: 20),
            drawView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor, constant: -20),
            drawView.heightAnchor.constraint(equalTo: drawView.widthAnchor),
        ])

        drawView.setDrawColor(color: .blue)
        drawView.setDrawWidth(width: 3.0)
    }
}
