• ColorHist. For more information, see GetValue(ColorHist, Index, [Color]).
• Delay. For more information, see GetValue(Delay).
• Hist. For more information, see GetValue(Hist, Index).

For more information, see Vision Data Access Functions.

Using GetValue:

The general syntax of GetValue is as follows:

GetValue(Structure,[Index],[Color])

• Where Structure is a reference to a cell containing a ColorHist, Delay, or Hist data structure.
• Index optionally specifies the bin from which to count histrogram values (ColorHist and Hist only)
• Color optionally determines which color component is used to pull Histogram data (ColorHist only)
