## Definition

Important

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

## Overloads

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. |

TranslateTransform(Single, Single) |
Changes the origin of the coordinate system by prepending the specified translation to the transformation matrix of this Graphics. |

## 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

The x-coordinate of the translation.

- dy
- Single

The y-coordinate of the translation.

- order
- 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.

{
// 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.
