CanvasCommand Constructor(RasterImage,int,int)

Summary

Initializes a new CanvasCommand class object with explicit parameters.

Syntax

C++

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

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

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.

Example

This procedure run a CanvasCommand of the image using canvasImage.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void CanvasConstructorExample_S1() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg")); 
   RasterImage canvasImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "ULAY1.BMP")); 
 
   // Prepaire the command 
   CanvasCommand canvasCommand = new CanvasCommand(canvasImage, 100, 100); 
   canvasCommand.XOffset = 10; 
   canvasCommand.YOffset = 10; 
   canvasCommand.Flags = CanvasCommandFlags.TileFit | CanvasCommandFlags.ResizeBicubic; 
 
   // Apply the command. 
   canvasCommand.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
