The Scale element gives more control over scaling than using Item 's scale property. Specifically, it allows a different scale 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 Rectangle, relative to its interior point 25, 25:
Rectangle { width: 100; height: 100 color: "blue" transform: Scale { origin.x: 25; origin.y: 25; xScale: 3} }

The point that the item is scaled from (i.e., the point that stays fixed relative to the parent as the rest of the item grows). By default the origin is 0, 0.
The scaling factor for the X axis.
The scaling factor for the Y axis.
