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 function SetLocation(
    location : AnalysisRegion
)

Parameters

location
Type: Microsoft.Ink.AnalysisRegion

The location where the non-ink image is on the application document, in ink coordinates.

Remarks

The location is set in ink coordinates.

Examples

The following example adds an ImageNode object to an InkAnalyzer, theInkAnalyzer, for a PictureBox control, thePictureBox. It converts the location of the PictureBox control from pixel coordinates to ink coordinates. It sets the Data property of the ImageNode object to be the Image property of the PictureBox.

' 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,
    thePictureBox.Bottom);
Graphics panelGraphics = theNotesPanel.CreateGraphics();
theInkCollector.Renderer.PixelToInkSpace(panelGraphics, ref pictureTopLeft);
theInkCollector.Renderer.PixelToInkSpace(panelGraphics, ref 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 (System.IO.MemoryStream stream = new System.IO.MemoryStream())
{
    thePictureBox.Image.Save(stream, thePictureBox.Image.RawFormat);
    pictureNode.Data = stream.ToArray();
}
