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

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

Syntax

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

instance.PixelToInkSpace(hdc, pt)

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

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

public function PixelToInkSpace(
    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 an ink space location.

Remarks

The PixelToInkSpace method converts from pixel to ink space—where one HIMETRIC unit = .01mm, applies the inverse of the view transform, and then applies the object transform.

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