Summary

Initializes a new FastMagicWandCommand class object with explicit parameters.

Syntax

C#
VB
C++
Public Function New( _ 
   ByVal sourceImage As Leadtools.RasterImage, _ 
   ByVal x As Integer, _ 
   ByVal y As Integer, _ 
   ByVal tolerance As Integer _ 
) 
public: 
FastMagicWandCommand(  
   Leadtools.RasterImage^ sourceImage, 
   int x, 
   int y, 
   int tolerance 
) 

Parameters

sourceImage
RasterImage object that references the source image.

x
The X position of the starting point.

y
The Y position of the starting point.

tolerance
The upper and lower color distance with relation to the starting point. For instance if the "tolerance" parameter is 25 and the color value at the starting point is 50. Then any adjacent pixel with a color range between 25 and 75 will be included in the region.

Example

Runs the FastMagicWandCommand on the Image.

C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void FastMagicWandCommandConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
   // Prepare the command 
   // Apply a FastMagicWand with specific parameters 
   FastMagicWandCommand command = new FastMagicWandCommand(image, 50, 50, 50); 
 
   command.StartEngine(); 
   command.Run(image); 
   command.EndEngine(); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images"; 
}

   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")) 
 
 
   Dim command As FastMagicWandCommand = New FastMagicWandCommand(leadImage, 50, 50, 50) 
   command.StartEngine() 
   command.Run(leadImage) 
   command.EndEngine()
