ChangeFromHBitmap(IntPtr,IntPtr,IntPtr) Method
See Also 



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.
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 LEADTOOLS Leadtools.RasterImage object.

Syntax

Visual Basic (Declaration) 
Overloads Public 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 = RasterImageConverter.ChangeFromHBitmap(hdc, hbitmap, hpalette)
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 Leadtools.RasterImage object.

Example

For an example, refer to ChangeToHBitmap(RasterImage).

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.

For more information refer to RasterImage and GDI/GDI+.

Requirements

Target Platforms: Silverlight 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
