## TranslateTransform(Single, Single, MatrixOrder)TranslateTransform(Single, Single, MatrixOrder)TranslateTransform(Single, Single, MatrixOrder)TranslateTransform(Single, Single, MatrixOrder)

Changes the origin of the coordinate system by applying the specified translation to the transformation matrix of this Graphics in the specified order.

``````public:
void TranslateTransform(float dx, float dy, System::Drawing::Drawing2D::MatrixOrder order);``````
``public void TranslateTransform (float dx, float dy, System.Drawing.Drawing2D.MatrixOrder order);``
``member this.TranslateTransform : single * single * System.Drawing.Drawing2D.MatrixOrder -> unit``
``Public Sub TranslateTransform (dx As Single, dy As Single, order As MatrixOrder)``

#### Parameters

dx
Single Single Single Single

The x-coordinate of the translation.

dy
Single Single Single Single

The y-coordinate of the translation.

order
MatrixOrder MatrixOrder MatrixOrder MatrixOrder

Member of the MatrixOrder enumeration that specifies whether the translation is prepended or appended to the transformation matrix.

### Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs`e`, which is a parameter of the Paint event handler. The code performs the following actions:

• Rotates the world transformation matrix of the Windows Form by 30.0F degrees.

• Moves the graphics object's origin by calling TranslateTransform, appending the translation to the world transformation matrix.

• Draws a rotated, translated ellipse with a blue pen.

``````public:
void TranslateTransformAngleMatrixOrder( PaintEventArgs^ e )
{
// Set world transform of graphics object to rotate.
e->Graphics->RotateTransform( 30.0F );

// Then to translate, appending to world transform.
e->Graphics->TranslateTransform( 100.0F, 0.0F, MatrixOrder::Append );

// Draw rotated, translated ellipse to screen.
e->Graphics->DrawEllipse( gcnew Pen( Color::Blue,3.0f ), 0, 0, 200, 80 );
}
``````
``````private void TranslateTransformAngleMatrixOrder(PaintEventArgs e)
{

// Set world transform of graphics object to rotate.
e.Graphics.RotateTransform(30.0F);

// Then to translate, appending to world transform.
e.Graphics.TranslateTransform(100.0F, 0.0F, MatrixOrder.Append);

// Draw rotated, translated ellipse to screen.
e.Graphics.DrawEllipse(new Pen(Color.Blue, 3), 0, 0, 200, 80);
}
``````
``````Private Sub TranslateTransformAngleMatrixOrder(ByVal e As PaintEventArgs)

' Set world transform of graphics object to rotate.
e.Graphics.RotateTransform(30.0F)

' Then to translate, appending to world transform.
e.Graphics.TranslateTransform(100.0F, 0.0F, MatrixOrder.Append)

' Draw rotated, translated ellipse to screen.
e.Graphics.DrawEllipse(New Pen(Color.Blue, 3), 0, 0, 200, 80)
End Sub
``````

### Remarks

The translation operation consists of multiplying the transformation matrix by a matrix whose translation part is the `dx` and `dy` parameters. This method prepends or appends the transformation matrix of the Graphics by the translation matrix according to the `order` parameter.

## TranslateTransform(Single, Single)TranslateTransform(Single, Single)TranslateTransform(Single, Single)TranslateTransform(Single, Single)

Changes the origin of the coordinate system by prepending the specified translation to the transformation matrix of this Graphics.

``````public:
void TranslateTransform(float dx, float dy);``````
``public void TranslateTransform (float dx, float dy);``
``member this.TranslateTransform : single * single -> unit``
``Public Sub TranslateTransform (dx As Single, dy As Single)``

#### Parameters

dx
Single Single Single Single

The x-coordinate of the translation.

dy
Single Single Single Single

The y-coordinate of the translation.

### Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs`e`, which is a parameter of the Paint event handler. The code performs the following actions:

• Rotates the world transformation matrix of the Windows Form by 30.0F degrees.

• Moves the origin of the graphics object by calling TranslateTransform, prepending the translation to the transformation matrix.

• Draws a translated, rotated ellipse with a blue pen.

``````public:
void TranslateTransformAngle( PaintEventArgs^ e )
{
// Set world transform of graphics object to rotate.
e->Graphics->RotateTransform( 30.0F );

// Then to translate, prepending to world transform.
e->Graphics->TranslateTransform( 100.0F, 0.0F );

// Draw translated, rotated ellipse to screen.
e->Graphics->DrawEllipse( gcnew Pen( Color::Blue,3.0f ), 0, 0, 200, 80 );
}
``````
``````private void TranslateTransformAngle(PaintEventArgs e)
{

// Set world transform of graphics object to rotate.
e.Graphics.RotateTransform(30.0F);

// Then to translate, prepending to world transform.
e.Graphics.TranslateTransform(100.0F, 0.0F);

// Draw translated, rotated ellipse to screen.
e.Graphics.DrawEllipse(new Pen(Color.Blue, 3), 0, 0, 200, 80);
}
``````
``````Private Sub TranslateTransformAngle(ByVal e As PaintEventArgs)

' Set world transform of graphics object to rotate.
e.Graphics.RotateTransform(30.0F)

' Then to translate, prepending to world transform.
e.Graphics.TranslateTransform(100.0F, 0.0F)

' Draw translated, rotated ellipse to screen.
e.Graphics.DrawEllipse(New Pen(Color.Blue, 3), 0, 0, 200, 80)
End Sub
``````

The following illustration shows the output of running the previous code example.

### Remarks

The origin is typically the upper-left-hand corner of the drawing surface. The translation operation consists of multiplying the transformation matrix by a matrix whose translation part is the `dx` and `dy` parameters. This method applies the translation by prepending the translation matrix to the transformation matrix.
