ResizeInterpolate Method

Summary

Applies different kinds of algorithms on images to resize them into the desired size.

Syntax

C++

[FaultContractAttribute(System.Type)]

   AsyncPattern=false, 
   IsOneWay=false, 
   IsInitiating=true, 
   IsTerminating=false)] 
public CommandResponse ResizeInterpolate( 
   ResizeInterpolateRequest request 
)

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

Parameters

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

Return Value

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

Remarks

This operation keeps the same bitmap handle and resizes the bitmap that it references.
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.
