Scale Method

Summary

Scales the transformation matrix of this AnnObject by the specified ratios.

Syntax

C++

public virtual void Scale( 
   float sx, 
   float sy, 
   AnnPoint origin 
)

  
Public Overridable Sub Scale( _ 
   ByVal sx As Single, _ 
   ByVal sy As Single, _ 
   ByVal origin As Leadtools.Annotations.AnnPoint _ 
)

public: 
virtual void Scale(  
   float sx, 
   float sy, 
   Leadtools.Annotations.AnnPoint origin 
)

Parameters

sx
The ratio by which to scale the Transform matrix in the x-axis direction.

sy
The ratio by which to scale the Transform matrix in the y-axis direction.

origin
An AnnPoint structure that represents the center of the scale operation.

Remarks

If the object implements auto transformation (TransformObjectMode returns .Auto), the logical coordinates of the object do not change when this method is called. Instead, the Transform matrix is updated and the effect is only applied when transforming the object to physical space (e.g. when drawing or hit-testing the object).

If the object implements point transformation (TransformObjectMode returns .Points), the logical coordinates of the object might change when this method is called. The exact behavior depends upon the object's implementation of the GetTransformPoints and the SetTransformPoints methods.

Example

For an example, refer to Transform.
