Constructor Summary

ImageInfoOp(java.awt.image.RenderedImage source, int param1)
Takes the source image and calls the superclass with this also constructs a GlobalStat object that computes all the available statistics once rather than compute them on demand seperately

Method Summary

protected void	accumulateStatistics(java.lang.String name, java.awt.image.Raster source, java.lang.Object stats) this function should gather the statistics but it uses the GlobalStats object which is created in the constructor
protected java.lang.Object	createStatistics(java.lang.String name) Creates the statistics object to store the statistics this is just an array whose size = number of bands of the image
protected java.lang.String[]	getStatisticsNames()

Constructor Detail

ImageInfoOp

public ImageInfoOp(java.awt.image.RenderedImage source,
                   int param1)

Takes the source image and calls the superclass with this also constructs a GlobalStat object that computes all the available statistics once rather than compute them on demand seperately

Method Detail

createStatistics

protected java.lang.Object createStatistics(java.lang.String name)

Creates the statistics object to store the statistics this is just an array whose size = number of bands of the image

Specified by:

createStatistics in class javax.media.jai.StatisticsOpImage

Parameters:

name - - String name of the statistic value

getStatisticsNames

protected java.lang.String[] getStatisticsNames()

Specified by:

getStatisticsNames in class javax.media.jai.StatisticsOpImage

accumulateStatistics

protected void accumulateStatistics(java.lang.String name,
                                    java.awt.image.Raster source,
                                    java.lang.Object stats)

this function should gather the statistics but it uses the GlobalStats object which is created in the constructor

Specified by:

accumulateStatistics in class javax.media.jai.StatisticsOpImage
