CreateRotateMatrix Method

Show in webframe





The angle (extent) of the rotation in degrees.
An AnnPoint structure that represents the center of the rotation.
An AnnUnitConverter object that can be used to convert the origin point from one unit to another (usually to pixels).
A helper method that creates a standard rotation matrix with the specified values.
Syntax
public static Matrix CreateRotateMatrix( 
   float angle,
   AnnPoint origin,
   AnnUnitConverter unitConverter
)
'Declaration
 
Public Shared Function CreateRotateMatrix( _
   ByVal angle As Single, _
   ByVal origin As AnnPoint, _
   ByVal unitConverter As AnnUnitConverter _
) As Matrix
'Usage
 
Dim angle As Single
Dim origin As AnnPoint
Dim unitConverter As AnnUnitConverter
Dim value As Matrix
 
value = AnnObject.CreateRotateMatrix(angle, origin, unitConverter)

            

            
public:
static Matrix^ CreateRotateMatrix( 
   float angle,
   AnnPoint origin,
   AnnUnitConverter^ unitConverter
) 

Parameters

angle
The angle (extent) of the rotation in degrees.
origin
An AnnPoint structure that represents the center of the rotation.
unitConverter
An AnnUnitConverter object that can be used to convert the origin point from one unit to another (usually to pixels).

Return Value

The System.Drawing.Drawing2D.Matrix that this method creates.
Remarks
