CanvasCommand Constructor(RasterImage,Int32,Int32)








Leadtools.ImageProcessing.SpecialEffects Namespace > CanvasCommand Class > CanvasCommand Constructor : CanvasCommand Constructor(RasterImage,Int32,Int32)
References the canvas image.
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.
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.

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.
