Type: PrecisionImage SourceData
A SourceData type containing the transformed data, or one with the same dimensions as that containing the data.
Type: OnlineSystem Int32
An OnlineInt32 type indicating the current decomposition level of the data.

Return Value

An OnlineInt32Rect type containing the coordinates of the average signal sub-band in the specified decomposition level.

Use this method to determine the coordinates of the average signal sub-band in the forward-transformed source data object. Note that in addition to the decomposition level, the coordinates are also a function of the dimensions of the transformed data. The SourceData object passed into the method as the sourceData argument does not necessarily need to have been transformed via ComputeForwardDWT(SourceData, Int32, SourceData, Int32, Wavelet, Int32), it just needs to have the same dimensions as the SourceData object of interest. It's usually most convenient to just use the transformed object, however.
