ScaleEffect.ByY Property (PowerPoint)
Sets or returns a Single that represents scaling or moving an object vertically by a specified percentage of the screen width, depending on whether it is used in conjunction with a ScaleEffect or MotionEffect object, respectively. Read/write.
Syntax
expression .ByY
expression A variable that represents a ScaleEffect object.
Return Value
Single
Remarks
Negative numbers move the object horizontally to the left. Floating point numbers (for example, 55.5) are allowed.
To scale or move an object horizontally, use the ByX property.
If both the ByX and ByY properties are set, then the object is scaled or moves both horizontally and vertically.
Do not confuse this property with the By property of the ColorEffect , RotationEffect , or PropertyEffect objects, which is used to set colors, rotations, or other properties of an animation behavior, respectively.
Example
The following example adds an animation path; then sets the horizontal and vertical movement of the shape.
Sub AddMotionPath()
Dim effCustom As Effect
Dim animBehavior As AnimationBehavior
Dim shpRectangle As Shape
'Adds rectangle and sets effect and animation
Set shpRectangle = ActivePresentation.Slides(1).Shapes _
.AddShape(Type:=msoShapeRectangle, Left:=300, _
Top:=300, Width:=300, Height:=150)
Set effCustom = ActivePresentation.Slides(1).TimeLine _
.MainSequence.AddEffect(Shape:=shpRectangle, _
effectId:=msoAnimEffectCustom)
Set animBehavior = effCustom.Behaviors.Add(msoAnimTypeMotion)
'Specifies animation motion
With animBehavior.MotionEffect
.ByX = 50
.ByY = 50
End With
End Sub
