Ink.AddStrokesAtRectangle 方法
指定已知的 Strokes 集合，在指定矩形處插入這個 Ink 物件。
命名空間： Microsoft.Ink
組件： Microsoft.Ink (在 Microsoft.Ink.dll 中)
語法
'宣告
Public Sub AddStrokesAtRectangle ( _
strokes As Strokes, _
destinationRectangle As Rectangle _
)
'用途
Dim instance As Ink
Dim strokes As Strokes
Dim destinationRectangle As Rectangle
instance.AddStrokesAtRectangle(strokes, _
destinationRectangle)
public void AddStrokesAtRectangle(
Strokes strokes,
Rectangle destinationRectangle
)
public:
void AddStrokesAtRectangle(
Strokes^ strokes,
Rectangle destinationRectangle
)
public void AddStrokesAtRectangle(
Strokes strokes,
Rectangle destinationRectangle
)
public function AddStrokesAtRectangle(
strokes : Strokes,
destinationRectangle : Rectangle
)
參數
- strokes
型別：Microsoft.Ink.Strokes
要加入至 Ink 物件的 Strokes 集合。
- destinationRectangle
型別：System.Drawing.Rectangle
要加入筆劃的矩形，以筆墨空間座標表示。
備註
如果矩形座標為 {0,0,0,0}，則會擲回執行階段錯誤。
筆劃在插入時會從 Strokes 集合的週框方塊，縮放到矩形中。
這個方法可以用來複製單一 Ink 物件內的筆劃。來源筆劃不一定要來自其他 Ink 物件。
範例
這個 C# 範例會使用 AddStrokesAtRectangle 方法從主物件 InkCollector (panelMain) 建立筆墨的複本，複製到 InkCollector 物件 (panelThumb) 中，同時維持適當的縮放比例和外觀比例 (Aspect Ratio)。為了維持目前的縮圖面板，會在 panelMain 中加入 Stroke 事件處理常式 (panelMain_Stroke)。
private void panelMain_Stroke(object sender, Microsoft.Ink.InkCollectorStrokeEventArgs e)
{
// Create a bounding rectangle for panelThumb in ink space coordinates
Point thePoint = Point.Empty;
using (Graphics g = Graphics.FromHwnd(Handle))
{
thePoint = new Point(panelThumb.Width, panelThumb.Height);
panelMain.Renderer.PixelToInkSpace(g, ref thePoint);
}
Rectangle theRectangle = new Rectangle(0, 0, thePoint.X, thePoint.Y);
// Delete the old strokes in the thumbnail, and add the new strokes.
panelThumb.Ink.DeleteStrokes();
// The strokes are automatically scaled to the destination rectangle
panelThumb.Ink.AddStrokesAtRectangle(panelMain.Ink.Strokes, theRectangle);
Refresh();
