命名空間：  Microsoft.Ink
組件：  Microsoft.Ink.Analysis (在 Microsoft.Ink.Analysis.dll 中)

語法

'宣告
Public Sub SetLocation ( _
    location As AnalysisRegion _
)
'用途
Dim instance As ImageNode
Dim location As AnalysisRegion

instance.SetLocation(location)

public void SetLocation(
    AnalysisRegion location
)

參數

備註

位置會以筆墨座標設定。

範例

下列範例會將 ImageNode 物件加入至 PictureBox (英文) 控制項 (變數名稱為 thePictureBox) 的 InkAnalyzer (變數名稱為 theInkAnalyzer)。範例中會將 PictureBox 控制項的位置從像素座標轉換為筆墨座標。它會將 ImageNode 物件的 Data 屬性設定為 PictureBox 的 Image 屬性。

' 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();
}
