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.

pt
Тип: System.Drawing.Point%
The point to convert into a pixel location.

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, the bounding box of an Ink object is obtained, and the center of the bounding box is determined. The center point is then converted to pixel coordinates and used by the Graphics object to draw a small red circle.

' get the ink bounds (ink space units)
Dim inkBounds As Rectangle = mInkOverlay.Ink.GetBoundingBox()
' create a Point in the center of the ink bounds (ink space units)
Dim centerPt As Point = _
       New Point(inkBounds.X + (inkBounds.Width / 2), _
                 inkBounds.Y + (inkBounds.Height / 2))

Using g As Graphics = mInkOverlay.AttachedControl.CreateGraphics()
    ' convert to pixel space
    mInkOverlay.Renderer.InkSpaceToPixel(g, centerPt)
    ' draw a small circle
    g.DrawEllipse(Pens.Red, centerPt.X - 5, centerPt.Y - 5, 10, 10)
End Using

// get the ink bounds (ink space units)
Rectangle inkBounds = mInkOverlay.Ink.GetBoundingBox();
// create a Point in the center of the ink bounds (ink space units)
Point centerPt = 
    new Point(inkBounds.X + (inkBounds.Width / 2), 
              inkBounds.Y + (inkBounds.Height / 2));

using (Graphics g = mInkOverlay.AttachedControl.CreateGraphics())
{
    // convert to pixel space
    mInkOverlay.Renderer.InkSpaceToPixel(g, ref centerPt);
    // draw a small circle
    g.DrawEllipse(Pens.Red, centerPt.X - 5, centerPt.Y - 5, 10, 10);
}
