Public Function GetBitmap ( _ width As Integer, _ height As Integer _ ) As Bitmap |
Parameters
- width
- Type: System..::.Int32
The width of the Bitmap in pixels.
- height
- Type: System..::.Int32
The height of the Bitmap in pixels.
Return Value
A Bitmap object which represents a scaled version of the Raster.Remarks
Any unfilled areas of the Bitmap are set to a System.Drawing.Color.Transparent color.
Examples
The code below provides two examples of using the GetBitmap method to save a scaled version of a
file geodatabase raster to disk.
