ImageNode.SetLocation-Methode
Legt die Position des Nicht-Freihandbilds im Anwendungsdokument fest.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink.Analysis (in Microsoft.Ink.Analysis.dll)
Syntax
'Declaration
Public Sub SetLocation ( _
location As AnalysisRegion _
)
'Usage
Dim instance As ImageNode
Dim location As AnalysisRegion
instance.SetLocation(location)
public void SetLocation(
AnalysisRegion location
)
public:
void SetLocation(
AnalysisRegion^ location
)
public void SetLocation(
AnalysisRegion location
)
public function SetLocation(
location : AnalysisRegion
)
Parameter
- location
Typ: Microsoft.Ink.AnalysisRegion
Die Position, an der sich das Nicht-Freihandbild im Anwendungsdokument befindet, wird in Freihandkoordinaten angegeben.
Hinweise
Die Position wird in Freihandkoordinaten festgelegt.
Beispiele
Im folgenden Beispiel wird dem InkAnalyzer mit dem Namen theInkAnalyzer, für das PictureBox-Steuerelement thePictureBox ein ImageNode-Objekt hinzugefügt. Konvertiert die Position des PictureBox-Steuerelements von Pixelkoordinaten in Freihandkoordinaten. Legt die Data-Eigenschaft des ImageNode-Objekts auf die Image-Eigenschaft der PictureBox fest.
' Add image node
Dim pictureNode As ImageNode = _
theInkAnalyzer.RootNode.CreateSubNode(Microsoft.Ink.ContextNodeType.Image)
' Convert pixel coordinates to pixel coordinates
Dim pictureTopLeft As Point = thePictureBox.Location
Dim pictureBottomRight As New Point(thePictureBox.Right, thePictureBox.Bottom)
Dim panelGraphics As Graphics = theNotesPanel.CreateGraphics()
theInkCollector.Renderer.PixelToInkSpace(panelGraphics, pictureTopLeft)
theInkCollector.Renderer.PixelToInkSpace(panelGraphics, pictureBottomRight)
panelGraphics.Dispose()
' Set the location of the image node
pictureNode.SetLocation(New AnalysisRegion(New Rectangle(pictureTopLeft.X, _
pictureTopLeft.Y, pictureBottomRight.X - pictureTopLeft.X, _
pictureBottomRight.Y - pictureTopLeft.Y)))
' Serialize the image to a byte array and set ImageNode.Data to the array.
Using stream As System.IO.MemoryStream = New System.IO.MemoryStream()
thePictureBox.Image.Save(stream, thePictureBox.Image.RawFormat)
pictureNode.Data = stream.ToArray()
End Using
// Add image node
ImageNode pictureNode = (ImageNode)
theInkAnalyzer.RootNode.CreateSubNode(Microsoft.Ink.ContextNodeType.Image);
// Convert pixel coordinates to pixel coordinates
Point pictureTopLeft = thePictureBox.Location;
Point pictureBottomRight = new Point(thePictureBox.Right,

// Serialize the image to a byte array and set ImageNode.Data to the array.
