Rough (Swift)
Rough lets you draw in a sketchy, hand-drawn-like, style. It is Swift clone of Rough.js. The library defines primitives to draw lines, curves, arcs, polygons, circles, and ellipses.
Requirements
Xcode 9, iOS 9
Installation
Rough is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'Rough'
Usage
let canvas = roughView.canvas
canvas.rectangle(origin: CGPoint(x: 10, y: 10), width: 200, height: 100)
roughView.setNeedsDisplay()
Lines and Ellipses
canvas.circle(center: CGPoint(x: 80, y: 120), radius: 25)
canvas.ellipse(center: CGPoint(x: 300, y: 100), width: 150, height: 80)
canvas.line(from: CGPoint(x: 80, y: 120), to: CGPoint(x: 300, y: 100))
Filling
canvas.circle(center: CGPoint(x: 50, y: 50), radius: 40) { options in
options.fill = UIColor.red
} // fill with red hachure
canvas.rectangle(origin: CGPoint(x: 120, y: 15), width: 80, height: 80) { options in
options.fill = UIColor.red
}
canvas.circle(center: CGPoint(x: 50, y: 150), radius: 40) {
options in
options.fill = UIColor(red: 10/255.0, green: 150/255.0, blue: 10/255.0, alpha: 1.0)
options.fillWeight = 3 // thicker lines for hachure
}
canvas.rectangle(origin: CGPoint(x: 220, y: 15), width: 80, height: 80) { options in
options.fill = UIColor.red
options.hachureAngle = 60 // angle of hachure
options.hachureGap = 8
}
canvas.rectangle(origin: CGPoint(x: 120, y: 105), width: 80, height: 80) { options in
options.fill = UIColor(red: 1.0, green: 0, blue: 200/255.0, alpha: 0.2)
options.fillStyle = .solid // solid fill
}
Sketching style
canvas.rectangle(origin: CGPoint(x: 15, y: 15), width: 80, height: 80) { options in
options.roughness = 0.5
options.fill = UIColor.red
}
canvas.rectangle(origin: CGPoint(x: 120, y: 15), width: 80, height: 80) { options in
options.roughness = 2.8
options.fill = UIColor.blue
}
canvas.rectangle(origin: CGPoint(x: 220, y: 15), width: 80, height: 80) { options in
options.bowing = 6
options.stroke = UIColor.green
options.strokeWidth = 3
}
