Leadtools.ImageProcessing.SpecialEffects Namespace > CanvasCommand Class > CanvasCommand Constructor : CanvasCommand Constructor(RasterImage,Int32,Int32)



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.
Initializes a new CanvasCommand class object with explicit parameters.

Syntax

Visual Basic (Declaration)  
Public Function New( _
   ByVal canvasImage As RasterImage, _
   ByVal transparency As Integer, _
   ByVal emboss As Integer _
)
Visual Basic (Usage) Copy Code
Dim canvasImage As RasterImage
Dim transparency As Integer
Dim emboss As Integer
 
Dim instance As CanvasCommand(canvasImage, transparency, emboss)
C#  
public CanvasCommand( 
   RasterImage canvasImage,
   int transparency,
   int emboss
)
C++/CLI  
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
