ChangeFromHBitmap(IntPtr,IntPtr,IntPtr) Method






Handle to the device responsible for the conversion. The mapping mode of the device context must be MM_TEXT.
Handle to the DDB to be changed.
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
public static RasterImage ChangeFromHBitmap( 
   IntPtr hdc,
   IntPtr hbitmap,
   IntPtr hpalette
)
'Declaration
 
Public Overloads Shared Function ChangeFromHBitmap( _
   ByVal hdc As IntPtr, _
   ByVal hbitmap As IntPtr, _
   ByVal hpalette As IntPtr _
) As RasterImage
'Usage
 
Dim hdc As IntPtr
Dim hbitmap As IntPtr
Dim hpalette As IntPtr
Dim value As RasterImage
 
value = RasterImageConverter.ChangeFromHBitmap(hdc, hbitmap, hpalette)
public static RasterImage ChangeFromHBitmap( 
   IntPtr hdc,
   IntPtr hbitmap,
   IntPtr hpalette
)
 function Leadtools.Drawing.RasterImageConverter.ChangeFromHBitmap(IntPtr,IntPtr,IntPtr)( 
   hdc ,
   hbitmap ,
   hpalette 
)
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.
Remarks

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