Transform Property

Summary

Returns the current transformation System.Drawing.Drawing2D.Matrix of this AnnObject.

Syntax

C++

public Matrix Transform { get; }

  
Public ReadOnly Property Transform As Matrix

public: 
property Matrix^ Transform { 
   Matrix^ get(); 
}

Property Value

The current transformation System.Drawing.Drawing2D.Matrix of this AnnObject.

Remarks

Each annotation object has a transformation matrix associated with it. You can perform various operations on this matrix by calling ResetTransform, Translate, Scale and Rotate.

Derived annotation objects can control the transformation operation by overriding the TransformObjectMode property.

Example

This example will perform various transformation on an annotation object then shows its transformation matrix.

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.Codecs; 
using Leadtools.WinForms; 
using Leadtools.Drawing; 
 
private void AnnObject_Transform(AnnObject obj) 
{ 
   // show the matrix 
   ShowMatrix(obj.Transform); 
   obj.Translate(2, 3); 
   ShowMatrix(obj.Transform); 
   obj.Scale(1.5F, 1.5F, obj.Origin); 
   ShowMatrix(obj.Transform); 
   obj.Rotate(45, obj.Origin); 
   ShowMatrix(obj.Transform); 
   obj.ResetTransform(); 
   ShowMatrix(obj.Transform); 
} 
 
 
private void ShowMatrix(Matrix mat) 
{ 
   int index = 0; 
   for (int i = 0; i < 3; i++) 
   { 
      for (int j = 0; j < 2; j++) 
         Console.Write("{0}, ", mat.Elements[index++]); 
 
      Console.WriteLine("{0}", i == 2 ? "1" : "0"); 
      Console.WriteLine("---------"); 
   } 
}
