Direct Point to Point length measurement from single origin

cfarrell

Hi, 

Is it possible to measure multiple points on an image all from the same origin point using the Direct Point to Point measuring tool, so that all measurements start in the same exact spot? If so, how can I do this?

Thanks!
Collin

Colin --

If I was tackling the challenge that I believe you are describing, I would not try to tackle it with the LINE TOOL.  I would use the POINT TOOL.

If you designate the ORIGIN POINT as the FIRST POINT that you define and then designate all of the other POINTS, you can use the power of PREMIER or EXCEL to determine the DISTANCES from the ORIGIN to all of the OTHER POINTS.

Below is a SCREEN CAPTURE that illustrates this concept.

I hope this information is helpful.

Hi Collin,

This macro adjusts origin of the lines by the origin position of the first line:

    Public Sub SetOrigin
        If ThisApplication.ActiveImage IsNot Nothing Then
            Dim md As MediaCy.Addins.Measurements.McMMData, l As MediaCy.IQL.Features.McLines
            Dim p(1) As MediaCy.IQL.ObjectManager.SINGLEPOINT, p2 As MediaCy.IQL.ObjectManager.SINGLEPOINT

            md = ThisApplication.ActiveImage.MeasurementsData
            For Each f As MediaCy.IQL.Features.McFeatures In md.GetMcFeatures
                l = TryCast(f, MediaCy.IQL.Features.McLines)
                If l IsNot Nothing AndAlso l.Count > 1 Then
                    md.BeginUpdateBlock(True)
                    l.GetFeaturePoints(0, p) : p2 = p(0)
                    For i As Integer = 1 To l.Count - 1
                        l.GetFeaturePoints(i, p)
                        p(0) = p2 : l.SetFeaturePoints(i, p)
                    Next
                    md.BeginUpdateBlock(False)
                End If
            Next
        End If
    End Sub

Thanks,
Nikita.

Collin,

This tool already exists in the UI of Premier, so no macros necessary.

You just need select all the objects you want to measure distance from and then select the origin object and click the Minimum Distance button:

As the result the multiple minimum distance (Direct) lines will be created from objects to the last object, so you can get all the Length measurements and stats in the data table.

Collin,

Another option, if you just want to specify measurements origin to get relative position coordinates, is to specify Origin X/Y of the spatial calibration applied to the image.
In that case all position measurements (Centroids, Locations,...) will be reported relatively to this point:
