How to access measurement data in your App

PierreD · June 2013

Many Apps take advantage of the powerful measurement capabilities of Image-Pro Premier, whether it is Count/Size or simple Manual Measurements but what if your App needs to do more with the measurement data than what the built-in feature does? The following macro illustrates how a simple macro can have full access to the measurement results and statistics. A reference to MediaCy.Addins.Measurements.dll will be needed.

Imports MediaCy.Addins.Measurements

Public Module Macros

Public Sub GetData()
Dim data As McMMData
Dim stats(8) As Double

ThisApplication.Output.show

With measure.MeasurementsCommands.GetData(Nothing)
            .Run(ThisApplication.ActiveDocument, data)
End With

' Statistics '

Dim measure As New MeasEntry
        measure.Measurement=eMeasures.RgnArea
        data.CalcStatistics(measure,stats)

ThisApplication.Output.PrintMessage("Mean Area = " & stats(0))
ThisApplication.Output.PrintMessage("SD Area = " & stats(1))
ThisApplication.Output.PrintMessage("Min Area = " & stats(2))
ThisApplication.Output.PrintMessage("Max Area = " & stats(3))

' Values '

For i As Integer = 0 To data.Rows-1
Dim feature As McMMSubFeature = data.SubFeature(i)
ThisApplication.Output.PrintMessage(String.Format("Area({0}) = {1}",i,feature.Value(eMeasures.RgnArea)))
Next

End Sub

End Module

There is also a direct property that returns statistics as McMMData.Statistcs. The list of all measurement features can be retrieved using the SubFeatures property in "for each" loop.

Another version of the macro:

    Public Sub GetData2()
        Dim data As McMMData
        ThisApplication.Output.show

        With measure.MeasurementsCommands.GetData(Nothing)
            .Run(ThisApplication.ActiveDocument, data)
        End With

        With ThisApplication.Output
            ' Statistics '
            .PrintMessage("Mean Area = " & data.Statistics(eMeasures.RgnArea).Mean)
            .PrintMessage("Sum  Area = " & data.Statistics(eMeasures.RgnArea).Sum)
            ' Values '
            Dim i As Integer=0
            For Each sf As McMMSubFeature In data.SubFeatures
                .PrintMessage(String.Format("Area({0}) = {1}",i,sf.Value(eMeasures.RgnArea)))
                i+=1
            Next
        End With
    End Sub
