Adding Transforms Together

Before applying a transform to a view, you can append other transforms to it.

var t = Transform.makeScale(2, 2)
t.rotate(M_PI)
t.translate(Vector(10,10))
view.transform = t

Example

let img = Image("chop")!
canvas.add(img)

let dw = canvas.width/img.width
let dxdy = (Vector(img.center) - Vector(canvas.center))/dw
var scaleRotateTranslate = Transform.makeScale(dw, dw)
scaleRotateTranslate.rotate(M_PI)
scaleRotateTranslate.translate(dxdy)

let a = ViewAnimation(duration: 1.0) {
    img.transform = scaleRotateTranslate
}
a.delay = 1.0
a.animate()
