ScaleTo Method

Feb 23, 2012 at 4:28 AM

So I downloaded the toolkit, added the references and the ScaleTo Method is nowhere to be found. how do I use it?

Do you add "using Coding4Fun.Kinect.Wpf;"  ?

Yes I used this library .... but same problem ... sorry I am using KINECT to the Arduino ,,,

I really need help in this issue,,,

here is the code:

'Arduino start
Imports System
Imports System.IO.Ports
'Arduino end

Imports System.Text
Imports Microsoft.Research.Kinect.Nui
Imports Coding4Fun.Kinect.Wpf

Namespace SkeletalTracking
''' <summary>
''' Interaction logic for MainWindow.xaml

    Public Shared ScreenMaxY As Integer = 180

    ' Arduino end

    Public Sub New()


    End Sub

        nui.SkeletonEngine.SmoothParameters = parameters
' #End Region
        'add event to receive skeleton data

the bold is my problem ,,, sorry to pom in like that

This should work just fine with v1.6 and v1.7. You may get warnings about a version mismatch, but it should still work.
