To get the test values for the KeySpline test, you can: |
|||
1) Grab the WPF sample for KeySpline animations from https://github.com/microsoft/WPF-Samples/tree/master/Animation/KeySplineAnimations
|
|||
2) Add the following xaml somewhere: |
|||
<Button Content="Capture" |
|||
Click="Button_Click"/> |
|||
<ScrollViewer VerticalScrollBarVisibility="Visible"> |
|||
<TextBlock Name="CaptureData" |
|||
Text="---" |
|||
TextWrapping="Wrap" /> |
|||
</ScrollViewer> |
|||
3) Add the following code to the code behind: |
|||
private void Button_Click(object sender, RoutedEventArgs e) |
|||
{ |
|||
CaptureData.Text += string.Format("\n{0} | {1}", myTranslateTransform3D.OffsetX, (TimeSpan)ExampleStoryboard.GetCurrentTime(this)); |
|||
CaptureData.Text += |
|||
"\nKeySpline=\"" + mySplineKeyFrame.KeySpline.ControlPoint1.X.ToString() + "," + |
|||
mySplineKeyFrame.KeySpline.ControlPoint1.Y.ToString() + " " + |
|||
mySplineKeyFrame.KeySpline.ControlPoint2.X.ToString() + "," + |
|||
mySplineKeyFrame.KeySpline.ControlPoint2.Y.ToString() + "\""; |
|||
CaptureData.Text += "\n-----"; |
|||
} |
|||
4) Run the app, mess with the slider values, then click the button to capture output values |
