示例

 

' ========================================================================================

' The following example creates a texture brush and uses it to fill an ellipse. The code

' then gets the brush's image and draws it.

' ========================================================================================

SUB Example_GetImage (BYVAL hdc AS HDC)

 

  ' // Create a graphics object from the window device context

  DIM graphics AS CGpGraphics = hdc

  ' // Get the DPI scaling ratio

  DIM rxRatio AS SINGLE = graphics.GetDpiX / 96

  DIM ryRatio AS SINGLE = graphics.GetDpiY / 96

  ' // Set the scale transform

  graphics.ScaleTransform(rxRatio, ryRatio)

 

  ' // Create a texture brush, and use it to fill an ellipse.

  DIM pImage AS CGpImage = "HouseAndTree.gif"

  DIM textureBrush AS CGpTextureBrush = @pImage

  graphics.FillEllipse(@textureBrush, 0, 0, 200, 200)

 

  ' // Get the brush's image, and draw that image

  DIM pImage2 AS CGpImage

  textureBrush.GetImage(@pImage2)

  graphics.DrawImage(@pImage2, 10, 150)

 

END SUB
