function CanvasCommand( 
   canvasImage ,
   transparency ,
   emboss ,
   xOffset ,
   yOffset ,
   tileOffset ,

public:
CanvasCommand( 
   RasterImage^ canvasImage,

   int yOffset,
   int tileOffset,
   CanvasCommandFlags flags
)

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.
xOffset: The X distance between the canvas origin point and the image origin point (in pixels). Valid range is from -Canvas image width to +Canvas image width.
yOffset: The Y distance between the canvas origin point and the image origin point (in pixels). Valid range is from -Canvas image height to +Canvas image height.
tileOffset: The amount to shift every row of the canvas image from the origin. This parameter is not used when Flags is set to CanvasCommandFlags.TileFit.
flags: Flags that identify how to distribute the canvas image with respect to the image and how to handle resizing.
