Property Value

Type: Object
Remarks
These are not the same as McImage.RangeMin and McImage.RangeMax which are set by the user for floating point images, and represent the minimum and maximum possible values for integral image types. The values may also differ from the Min and Max McHistogram properties. The Min and Max properties give the BinXValues element of the lowest and highest, respectively, bins with non-zero counts. These values will usually differ from the AbsoluteRange for floating point image types and where the BinCount is less than MaxBinCount. AbsoluteRange is exposed as a 2D array ([IMcIMage.NumberOfChannels][2] in C, (0 to 1,0 to IMcIMage.NumberOfChannels-1) in VB) if Channel=-1, or an array containing two double precision floating point values if Channel is non-negative. If the source McImage.ActiveFrameRange specifies some frames, then unless the Mode mchmProcessActiveFrameOnly bit is set or the SampledFrame property is non-negative, the AbsoluteRange 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. The AbsoluteRange property honors the Interpretation property and also the Mode mchmApplyIntensityCalibration flag. If the Interpretation is one that has a natural luminance channel (e.g., mciHSL or mciHSI), then when the Mode mchmApplyIntensityCalibration flag is set, intensity calibration is only applied to the luminance channel.
