public CanvasCommand( 
   RasterImage canvasImage,
   int transparency,
   int emboss
)

'Declaration
 
Public Function New( _
   ByVal canvasImage As RasterImage, _
   ByVal transparency As Integer, _
   ByVal emboss As Integer _
)

'Usage
 
Dim canvasImage As RasterImage
Dim transparency As Integer
Dim emboss As Integer
 
Dim instance As New CanvasCommand(canvasImage, transparency, emboss)

public CanvasCommand( 
   RasterImage canvasImage,
   int transparency,
   int emboss
)

function CanvasCommand( 
   canvasImage ,
   transparency ,
   emboss 
)

public:
CanvasCommand( 
   RasterImage^ canvasImage,
   int transparency,
   int emboss
)

Parameters

canvasImage: References the canvas image.
transparency: The transparency amount between the image and the canvas. Valid range is from 0 to 100. When set to 0, only the canvas image displays, and when set to 100, the canvas image is barely visible.
emboss: Apparent depth of the canvas image. Valid range is from 0 to 200. When Transparency is at 100, and Emboss is 0 only the image displays. Increasing Emboss increases the apparent depth of the canvas image.
