   javax.media.jai.Interpolation
      com.sun.media.jai.util.InterpAverage

InterpAverage
public class InterpAverage extends Interpolation (Code)
An Interpolation class which performs simple averaging of all pixels within a specified neighborhood. It is used by the "SubsampleAverage" operation implementations.
since:
   JAI 1.1.2



Constructor Summary
public  InterpAverage(int blockX, int blockY)
     Creates an InterpAverage instance having the supplied dimensions.

Method Summary
public  intinterpolateH(int[] samples, int xfrac)
     Returns the average of all elements in samples; xfrac is ignored.
public  floatinterpolateH(float[] samples, float xfrac)
     Returns the average of all elements in samples; xfrac is ignored.
public  doubleinterpolateH(double[] samples, float xfrac)
     Returns the average of all elements in samples; xfrac is ignored.


Constructor Detail
InterpAverage
public InterpAverage(int blockX, int blockY)(Code)
Creates an InterpAverage instance having the supplied dimensions. The left and top padding are (blockX - 1)/2 and (blockY - 1)/2, respectively. The subsampleBitsH and subsampleBitsV instance variables are set to 32.
Parameters:
  blockX - The width of the interpolation block.
Parameters:
  blockY - The height of the interpolation block.
throws:
  IllegalArgumentException - if either parameter is non-positive.




Method Detail
interpolateH
public int interpolateH(int[] samples, int xfrac)(Code)
Returns the average of all elements in samples; xfrac is ignored.



interpolateH
public float interpolateH(float[] samples, float xfrac)(Code)
Returns the average of all elements in samples; xfrac is ignored.



interpolateH
public double interpolateH(double[] samples, float xfrac)(Code)
Returns the average of all elements in samples; xfrac is ignored.
