發行項
10/29/2008

從 Point 的輸入值陣列建立 Stroke 物件。

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

語法

'宣告
Public Function CreateStroke ( _
    points As Point() _
) As Stroke
'用途
Dim instance As Ink
Dim points As Point()
Dim returnValue As Stroke

returnValue = instance.CreateStroke(points)

public Stroke CreateStroke(
    Point[] points
)

public:
Stroke^ CreateStroke(
    array<Point>^ points
)

public Stroke CreateStroke(
    Point[] points
)

public function CreateStroke(
    points : Point[]
) : Stroke

參數

points
型別：array<System.Drawing.Point[]
組成 Stroke 物件的點陣列。

傳回值

型別：Microsoft.Ink.Stroke
新建立的筆劃。
新建立的 Stroke 物件。

備註

點陣列中任何點的最小值和最大值分別為 System.Int32.MinValue 和 System.Int32.MaxValue 欄位。然而，這些點所定義之筆墨空間矩形的最大寬度或高度不能超過 System.Int32.MaxValue。基於這個原因，X 座標最小值和最大值之間的差異，或者是 Y 座標最小值和最大值之間的差異，不能超過 System.Int32.MaxValue。

範例

在這個範例中，會在 Ink 物件中建立 Stroke 物件。筆劃會從筆墨區域的左上角經過右下角。

' get the bottom right point of the client area for ink
' Note: InkOverlay.AttachedControl property must be set
Dim bottomRight As Point = New Point(mInkOverlay.AttachedControl.ClientSize)
' convert to HIMETRIC units
Using g As Graphics = mInkOverlay.AttachedControl.CreateGraphics()
    mInkOverlay.Renderer.PixelToInkSpace(g, bottomRight)
End Using
' create the stroke
Dim strokePoints As Point() = New Point(1) {New Point(0), bottomRight}
mInkOverlay.Ink.CreateStroke(strokePoints)
mInkOverlay.AttachedControl.Invalidate()

// get the bottom right point of the client area for ink
// Note: InkOverlay.AttachedControl property must be set
Point bottomRight = new Point(mInkOverlay.AttachedControl.ClientSize);
// convert to HIMETRIC units
using (Graphics g = mInkOverlay.AttachedControl.CreateGraphics())
{
    mInkOverlay.Renderer.PixelToInkSpace(g, ref bottomRight);
}
// create the stroke
Point[] strokePoints = new Point[2] { new Point(0), bottomRight };
mInkOverlay.Ink.CreateStroke(strokePoints);
mInkOverlay.AttachedControl.Invalidate();
