SwiftUI教程第1章第19节：Image-Transform

 

给图像应用缩放、旋转等变形效果。
示例代码：

ScrollView{
            
    VStack{
	Image("girlPicture")
	    .scaleEffect(0.8)

	Image("girlPicture")
	    .scaleEffect(CGSize(width: 1.2, height: 1))

	Image("girlPicture")
	    .scaleEffect(x: 1.5, y: 1, anchor: UnitPoint.bottomLeading)
    }

     VStack{

	Image("girlPicture")
	     .rotationEffect(Angle.init(degrees: 90))

	Image("girlPicture")
	    .rotationEffect(Angle.init(degrees: 30), anchor: UnitPoint.init(x: 0, y: 0))

	Image("girlPicture")
	    .rotation3DEffect(Angle.init(degrees: 30), axis: (x: CGFloat(0.1), y: CGFloat(0.1), z: CGFloat(0)))

    }
}
