IMcHistogramCompute Method

Sub Compute ( 
	<OptionalAttribute> SourceImage As Object
)

Calculated values depend on BinCount, Interpretation, Mode and IMcImage.RangeMin, IMcImage.RangeMax for floating point images. Histogram results are based only on pixels interior to the source image's Aoi unless the Mode property mchmIgnoreAoi bit is set. You generally will not need to call Compute directly. This method is called automatically whenever one of the Histogram properties is requested and the cached data is not in sync with the parent image and the current Mode. It is also possible to pass an image parameter in order to compute the Histogram on an image when there is no ancestor McImage. Results can be accessed using the IMcHistogram properties RawValues, Values and BinXValues, as well as the standard statistical properties. If the source McImage.ActiveFrameRange specifies a Range, then unless the Mode mchmProcessActiveFrameOnly bit is set, then the histogram is computed from all of the specified frames. If the Mode mchmProcessActiveFrameOnly bit is set, then only the McImage.ActiveFrame is conisidered. If the Mode mchmIgnoreAoi bit is set, then any Aoi is ignored.
