Average Method

Summary

Changes the color of each pixel in an image to the average color of pixels in its neighborhood. This results in a blur effect.

Syntax

C++

[FaultContractAttribute(DetailType=Leadtools.Services.Raster.FaultContracts.RasterFault,  
   Action="",  
   Name="",  
   Namespace="",  
   ProtectionLevel=ProtectionLevel.None,  
   HasProtectionLevel=false)] 
[OperationContractAttribute("Average")] 
Leadtools.Services.Imageprocessing.Datacontracts.CommandResponse Average(  
   Leadtools.Services.Imageprocessing.Datacontracts.AverageRequest request 
)

<FaultContractAttribute(DetailType=Leadtools.Services.Raster.FaultContracts.RasterFault,  
   Action="",  
   Name="",  
   Namespace="",  
   ProtectionLevel=ProtectionLevel.None,  
   HasProtectionLevel=False)> 
<OperationContractAttribute("Average")> 
Function Average( _ 
   ByVal request As Leadtools.Services.Imageprocessing.Datacontracts.AverageRequest _ 
) As Leadtools.Services.Imageprocessing.Datacontracts.CommandResponse

[FaultContractAttribute(DetailType=Leadtools.Services.Raster.FaultContracts.RasterFault,  
   Action="",  
   Name="",  
   Namespace="",  
   ProtectionLevel=ProtectionLevel.None,  
   HasProtectionLevel=false)] 
[OperationContractAttribute("Average")] 
Leadtools.Services.Imageprocessing.Datacontracts.CommandResponse^ Average(  
   Leadtools.Services.Imageprocessing.Datacontracts.AverageRequest^ request 
)

Parameters

request
A System.Runtime.Serialization.DataContractAttribute containing the data that will be used in this Average operation.

Return Value

A System.Runtime.Serialization.DataContractAttribute containing the modified image resulting from the Average operation.

Remarks

You control the amount of blur by specifying the size of the neighborhood that is used for averaging.
This operation supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This operation does not support 32-bit grayscale images.

For more information, refer to Removing Noise.
