Renderer.InkSpaceToPixel 方法 (Graphics, array<Point[]%)

發行項
10/29/2008

藉由對轉換使用 Graphics (英文) 物件，將以筆墨空間座標表示的位置陣列轉換成以像素空間表示。

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

語法

'宣告
Public Sub InkSpaceToPixel ( _
    g As Graphics, _
    ByRef pts As Point() _
)
'用途
Dim instance As Renderer
Dim g As Graphics
Dim pts As Point()

instance.InkSpaceToPixel(g, pts)

public void InkSpaceToPixel(
    Graphics g,
    ref Point[] pts
)

public:
void InkSpaceToPixel(
    Graphics^ g, 
    array<Point>^% pts
)

public void InkSpaceToPixel(
    Graphics g,
    /** @ref */Point[] pts
)

public function InkSpaceToPixel(
    g : Graphics, 
    pts : Point[]
)

參數

g
型別：System.Drawing.Graphics
用於轉換的 Graphics (英文) 物件。通常這是來自事件引數或 System.Windows.Forms.Control.CreateGraphics (英文) 方法。

pts
型別：array<System.Drawing.Point[]%
要轉換成像素位置的點陣列。

備註

InkSpaceToPixel 方法會套用 Renderer 物件的物件轉換，套用檢視轉換，然後將 HIMETRIC 單位轉換為像素單位。

範例

在這個範例中，會將 InkOverlay 物件傳遞至一個方法。這個方法會傳回關聯之 Ink 物件的週框方塊 (以像素空間表示)。

Public Function GetInkBoundsInPixels(ByVal theInkOverlay As InkOverlay) As Rectangle
    ' Copy the bounding rectangle in ink space dimensions
    Dim theBoundingRectangle As Rectangle = theInkOverlay.Ink.GetBoundingBox()
    ' Get the top left and bottom right points
    Dim corners() As Point = _
            { _
              theBoundingRectangle.Location, _
              theBoundingRectangle.Location + theBoundingRectangle.Size _
            }
    Using g As Graphics = mInkOverlay.AttachedControl.CreateGraphics()
        ' Convert from ink space to pixel space
        theInkOverlay.Renderer.InkSpaceToPixel(g, corners)
    End Using
    Return New Rectangle(corners(0), _
        New Size(corners(1).X - corners(0).X, corners(1).Y - corners(0).Y))
End Function

public Rectangle GetInkBoundsInPixels(InkOverlay theInkOverlay)
{
    // Copy the bounding rectangle in ink space dimensions
    Rectangle theBoundingRectangle = theInkOverlay.Ink.GetBoundingBox();
    // Get the top left and bottom right points
    Point[] corners = new Point[2] 
        {
            theBoundingRectangle.Location,
            theBoundingRectangle.Location + theBoundingRectangle.Size
        };
    using (Graphics g = mInkOverlay.AttachedControl.CreateGraphics())
    {
        // Convert from ink space to pixel space
        theInkOverlay.Renderer.InkSpaceToPixel(g, ref corners);
    }
    return new Rectangle(corners[0],
        new Size(corners[1].X - corners[0].X, corners[1].Y - corners[0].Y));
}
