Leadtools Namespace > RasterImage Class > ChangeFromHBitmap Method : ChangeFromHBitmap(IntPtr,IntPtr,IntPtr) Method




hdc
Handle to the device responsible for the conversion. The mapping mode of the device context must be MM_TEXT.
hbitmap
Handle to the DDB to be changed.
hpalette
Handle to the palette. This value can be IntPtr.Zero if the hdc parameter refers to a device that is greater than 8 bits, or if the bitmap will use the system palette.
Changes a Windows device dependent bitmap (DDB) to a LEAD RasterImage object.

Syntax

Visual Basic (Declaration) 
Public Overloads Shared Function ChangeFromHBitmap( _
   ByVal hdc As IntPtr, _
   ByVal hbitmap As IntPtr, _
   ByVal hpalette As IntPtr _
) As RasterImage
Visual Basic (Usage)Copy Code
Dim hdc As IntPtr
Dim hbitmap As IntPtr
Dim hpalette As IntPtr
Dim value As RasterImage
 
value = RasterImage.ChangeFromHBitmap(hdc, hbitmap, hpalette)
C# 
public static RasterImage ChangeFromHBitmap( 
   IntPtr hdc,
   IntPtr hbitmap,
   IntPtr hpalette
)
Managed Extensions for C++ 
public: static RasterImage* ChangeFromHBitmap( 
   IntPtr hdc,
   IntPtr hbitmap,
   IntPtr hpalette
) 
C++/CLI 
public:
static RasterImage^ ChangeFromHBitmap( 
   IntPtr hdc,
   IntPtr hbitmap,
   IntPtr hpalette
) 

Parameters

hdc
Handle to the device responsible for the conversion. The mapping mode of the device context must be MM_TEXT.
hbitmap
Handle to the DDB to be changed.
hpalette
Handle to the palette. This value can be IntPtr.Zero if the hdc parameter refers to a device that is greater than 8 bits, or if the bitmap will use the system palette.

Return Value

The newly create RasterImage object.

Example

For an example, refer to ChangeToHBitmap.

Remarks

This method results in only one copy of the image, and it invalidates the DDB (hbitmap) handle.

For more information on DDBs and DIBs, refer to Using DIBs, DDBs, and the Clipboard.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
