DrawImage Method (ViewportLayout)

In This Topic

Draws an image on the ViewportLayout's client area.

Syntax

Visual Basic
C#

'Declaration
 
Protected Friend Sub DrawImage( _
   ByVal x As Integer, _
   ByVal y As Integer, _
   ByVal image As Bitmap _
)

protected internal void DrawImage( 
   int x,
   int y,
   Bitmap image
)

Parameters

x: The image's x corrdinate
y: The image's y coordinate (from the bottom of the viewport)
image: The image to draw

Remarks

Alpha channel is supported. Use the System.Drawing.Image.RotateFlip(System.Drawing.RotateFlipType) method to flip the image upside down.For better performances create a texture and call DrawTexture (see code below)

Example

The following code demonstrates how to efficiently draw an image on screen

private TextureBase texture1;
private bool firstTime = false;
protected override void DrawOverlay(DrawSceneParams data)
{
    base.DrawOverlay(data);
            
    if (!firstTime)
    {
        firstTime = true;
        texture1 = renderContext.CreateTexture2D(Properties.Resources.Smiley, textureFilteringFunctionType.Nearest, textureFilteringFunctionType.Nearest, true, true);        
        font.Dispose();
    }
            
    DrawTexture(texture1, 100, 100, ContentAlignment.BottomLeft);        
    // Remember to Dispose the texture when it is no more needed, or before quitting the application
}

Visual Basic

Private texture1 As TextureBase
Private firstTime As Boolean = False
Protected Overrides Sub DrawOverlay(data As DrawSceneParams)
	MyBase.DrawOverlay(data)
            
	If Not firstTime Then
		firstTime = True
		texture1 = renderContext.CreateTexture2D(Properties.Resources.Smiley, textureFilteringFunctionType.Nearest, textureFilteringFunctionType.Nearest, True, True)
		font.Dispose()
	End If
            
	DrawTexture(texture1, 100, 100, ContentAlignment.BottomLeft)
    ' Remember to Dispose the texture when it is no more needed, or before quitting the application
End Sub
