備註

ScaleTransform使用, 以水準或垂直方式延展或縮小物件。Use a ScaleTransform to stretch or shrink an object horizontally or vertically. 屬性會指定沿著 X 軸延展或縮小物件的程度, ScaleY而屬性會指定要沿著 y 軸延展或縮小物件的程度。 ScaleXThe ScaleX property specifies by how much to stretch or shrink an object along the x-axis, and the ScaleY property specifies by how much to stretch or shrink an object along the y-axis. 縮放作業會以CenterXCenterY屬性所指定的點為中心。Scale operations are centered on the point specified by the CenterX and CenterY properties.

無法凍結的功能: 因為它繼承自Freezable類別ScaleTransform , 所以類別會提供幾個特殊功能ScaleTransform : 物件可以宣告為, 在多個物件之間共用, 使其成為唯讀以改善效能、複製並使其成為安全線程。Freezable Features: Because it inherits from the Freezable class, the ScaleTransform class provides several special features: ScaleTransform objects can be declared as , shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. 如需Freezable物件所提供之不同功能的詳細資訊, 請參閱可凍結物件總覽For more information about the different features provided by Freezable objects, see Freezable Objects Overview.
