CanvasCommand Constructor(RasterImage,Int32,Int32)
See Also  Example
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 Leadtools.ImageProcessing.SpecialEffects.CanvasCommand class object with explicit parameters.

Example

This procedure run a Leadtools.ImageProcessing.SpecialEffects.CanvasCommand of the image using canvasImage.
