Summary

Initializes a new CanvasCommand class object with explicit parameters.

Syntax
C#
VB
C++
  
Public Function New( _ 
   ByVal canvasImage As RasterImage, _ 
   ByVal transparency As Integer, _ 
   ByVal emboss As Integer, _ 
   ByVal xOffset As Integer, _ 
   ByVal yOffset As Integer, _ 
   ByVal tileOffset As Integer, _ 
   ByVal flags As CanvasCommandFlags _ 
) 
public: 
CanvasCommand(  
   RasterImage^ canvasImage, 
   int transparency, 
   int emboss, 
   int xOffset, 
   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.

Example

This procedure run a CanvasCommand of the image using canvasImage.

VB
using Leadtools; 
using Leadtools.Codecs;

   // Prepaire the command 
   CanvasCommand canvasCommand = new CanvasCommand(canvasImage, 100, 100, 10, 10, 20, CanvasCommandFlags.TileFit); 
 
   // Apply the command. 
   canvasCommand.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
