Minimum Method

Summary

Dilates dark objects by the specified amount. This operation is available in the Document/Medical Toolkits.

Syntax

C++

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

<OperationContractAttribute("Minimum")> 
<FaultContractAttribute(DetailType=Leadtools.Services.Raster.FaultContracts.RasterFault,

   HasProtectionLevel=False)> 
Function Minimum( _ 
   ByVal request As Leadtools.Services.Imageprocessing.Datacontracts.MinimumRequest _ 
) As Leadtools.Services.Imageprocessing.Datacontracts.CommandResponse

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

Parameters

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

Return Value

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

Remarks

This operation can process the whole image or a region of the image.
The operation can be controlled by specifying the size of the neighborhood that is used for calculating each pixel value. For example, for 8x8, set the Leadtools.Services.ImageProcessing.DataContracts.MinimumRequest.Dimension property (or the dimension parameter of the Constructor)to 8. Each pixel is replaced with the minimum value of its neighborhood.
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.
