draw

Is there a method which returns the width ( in pixels ) of a text to be drawn on an Android canvas using the drawText() method according to the Paint used to draw it?

You can animate the end of the stroke of a path on a CAShapeLayer , e.g., weak var shapeLayer: CAShapeLayer? @IBAction func didTapButton(_ sender: Any) { // remove old shape layer if any self.shapeLayer?.removeFromSuperlayer() // create whatever path you want let path = UIBezierPath() path.move(to: CGPoint(x: 10, y: 50)) path.addLine(to: CGPoint(x: 200, y: 50)) path.addLine(to: CGPoint(x: 200, y: 240)) // create shape layer for that path let shapeLayer

I am trying to draw a rectangle around multiline text in iText. The user will be able to enter some lines of text. The font size of the text might be different and it can be formatted (bold, underlined...).

It sounds as if you are missing only a single piece of the puzzle to meet your requirement.

I would like to know how to draw a semi circle in JavaFX. I tried to use Shape and QuadCurve but I couldn't make a perfect semicircle.

The next 4 parameters are the x,y,width & height
