Параметры

g
Тип: System.Drawing.Graphics
The Graphics object to use for conversion. This generally comes from event arguments or from the System.Windows.Forms.Control.CreateGraphics method.

pts
Тип: array<System.Drawing.Point[]%
The array of points to convert into pixel locations.

Заметки

The InkSpaceToPixel method applies the object transform of the Renderer object, applies the view transform, and then converts from HIMETRIC to pixel units.

Примеры

In this example, an InkOverlay object is passed to a method. The method returns the the bounding box of the associated Ink object in pixel space.

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));
}
