IStatsHistogram4 Interface

Provides access to accumulating member variables. Allows for block-wise outside updating.

Members

	Name	Description
	Accumulate	Accumulates a value and its count.
	AccumulateCovariance	Accumulates covariance array, numValidPixel.
	Covariances	Array of doubles, the covariances with the n bands of the raster.
	Empty	Empties this RasterStatsHistogram and marks it invalid.
	GetCovarAccu	Get the accumulating or running variables used for covar computation. Continue to increment from here.
	HasHistogram	Checks if this StatsHistogram has histogram.
	HasStats	Checks if this StatsHistogram has stats.
	Histogram	The histogram values of the statistics.
	InitCovariances	Resizes covariance array to nBands, init all elements to 0.
	Max	The maximum value of the historgram.
	Mean	The mean value of the historgram.
	Min	The minimum value of the historgram.
	PixelCount	The total pixel count.
	PutCovarAccu	Put the accumulating or running variables used for covar computation. Do this after having incremented them.
	PutHistogramInfo	Sets histogram size, resolution, and min/max range.
	PutHistogramMinmax	Sets histogram min and max range.
	PutStats	Computes stats and histogram from a given Raster.
	QueryHistogramInfo	Gets histogram size, resolutiom, and min/max range.
	QueryHistogramMinmax	Gets histogram min and max range.
	QueryStats	Computes stats and histogram from a given Raster.
	RasterHistogram	The raster histogram.
	RasterStatistics	The raster statistics.
	StdDev	The standard deviation value of the historgram.
	Update	Updates the histogram after accumulation.
	UpdateCovariances	Final update after accumulate is finished.

IStatsHistogram4.GetCovarAccu Method
