Converts a location in ink space coordinates to be a location in pixel space by using a handle for the conversion.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
<PermissionSetAttribute(SecurityAction.InheritanceDemand, Name := "FullTrust")> _
<UIPermissionAttribute(SecurityAction.Demand, Window := UIPermissionWindow.SafeTopLevelWindows)> _
<SecurityPermissionAttribute(SecurityAction.Demand, UnmanagedCode := True)> _
Public Sub InkSpaceToPixel ( _
    hdc As IntPtr, _
    ByRef pt As Point _
)
'Usage
Dim instance As Renderer 
Dim hdc As IntPtr 
Dim pt As Point

instance.InkSpaceToPixel(hdc, pt)

[PermissionSetAttribute(SecurityAction.InheritanceDemand, Name = "FullTrust")]
[UIPermissionAttribute(SecurityAction.Demand, Window = UIPermissionWindow.SafeTopLevelWindows)]
[SecurityPermissionAttribute(SecurityAction.Demand, UnmanagedCode = true)]
public void InkSpaceToPixel(
    IntPtr hdc,
    ref Point pt
)

[PermissionSetAttribute(SecurityAction::InheritanceDemand, Name = L"FullTrust")]
[UIPermissionAttribute(SecurityAction::Demand, Window = UIPermissionWindow::SafeTopLevelWindows)]
[SecurityPermissionAttribute(SecurityAction::Demand, UnmanagedCode = true)]
public:
void InkSpaceToPixel(
    IntPtr hdc, 
    Point% pt
)

public function InkSpaceToPixel(
    hdc : IntPtr, 
    pt : Point
)

Parameters

hdc
Type: System.IntPtr

The handle of the containing control or form.

pt
Type: System.Drawing.Point%

The point to convert into a pixel location.

Remarks

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

To minimize memory leaks, use the InkSpaceToPixel(Graphics, Point%) overload of this method. The InkSpaceToPixel(IntPtr, Point%) overload requires that handles be kept in memory, which tends to result in leaks.
