详细描述

The Scale type provides a way to scale an item through a scale-type transform.

It allows different scaling values for the x and y axes, and allows the scale to be relative to an arbitrary point.

The following example scales the X axis of the Image, relative to its interior point (25, 25):

Image {
    width: 100; height: 100
    source: "qrc:/bluerect.png"
    transform: Scale { origin.x: 25; origin.y: 25; xScale: 3}
}
						

注意: Scaling is a slow operation on some platforms. When scaling images, use the QUL_OPTIMIZE_FOR_SCALE property on the resource to enable optimizations.

origin group

origin.x : real

origin.y : real

This property holds the point that the item is scaled from (that is, the point that stays fixed relative to the parent as the rest of the item grows).

The default value of the origin is (0, 0).


xScale : real

The scaling factor for the X axis.

默认值为 1.0。


yScale : real

The scaling factor for the Y axis.

默认值为 1.0。
