ESRI.ArcGIS.Client Namespace > ArcGISImageServiceLayer Class : Interpolation Property

The resampling process of extrapolating the pixel values while transforming the raster dataset when it undergoes warping or when it changes coordinate space.

Syntax

Visual Basic (Declaration) 
Public Property Interpolation As ArcGISImageServiceLayer.ImageServiceInterpolation
C# 
public ArcGISImageServiceLayer.ImageServiceInterpolation Interpolation {get; set;}

Remarks

The default interpolation method is the NearestNeighbor Enumeration.

There are four ArcGISImageServiceLayer.ImageServiceInterpolation Enumeration values that can be used in the Interpolation Property, they are:

  • NearestNeighbor
  • BilinearInterpolation
  • CubitConvolution
  • Majority

Theoretical information related to interpolation can be found for the following topics:
