Leadtools.Services.ImageProcessing.ServiceContracts Namespace > IFiltersProcessingService Interface : Average Method



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

Visual Basic (Declaration) 
<FaultContractAttribute(DetailType=Leadtools.Services.Raster.FaultContracts.RasterFault, 
   Action="", 
   Name="", 
   Namespace="", 
   HasProtectionLevel=False)>
<OperationContractAttribute("Average")>
Overridable Function Average( _
   ByVal request As AverageRequest _
) As CommandResponse
Visual Basic (Usage)Copy Code
Dim instance As IFiltersProcessingService
Dim request As AverageRequest
Dim value As CommandResponse
 
value = instance.Average(request)
C# 
[FaultContractAttribute(DetailType=Leadtools.Services.Raster.FaultContracts.RasterFault, 
   Action="", 
   Name="", 
   Namespace="", 
   HasProtectionLevel=false)]
[OperationContractAttribute("Average")]
virtual CommandResponse Average( 
   AverageRequest request
)
C++/CLI 
[FaultContractAttribute(DetailType=Leadtools.Services.Raster.FaultContracts.RasterFault, 
   Action="", 
   Name="", 
   Namespace="", 
   HasProtectionLevel=false)]
[OperationContractAttribute("Average")]
virtual CommandResponse Average( 
   AverageRequest request
)

Parameters

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

Return Value

A 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.
