ChangeFromHBitmap(IntPtr,IntPtr) Method

Summary

Changes a Windows Device-Dependent Bitmap (DDB) to a LEADTOOLS Leadtools.RasterImage object.

Syntax

C++

public static RasterImage ChangeFromHBitmap( 
   IntPtr hbitmap, 
   IntPtr hpalette 
)

Public Overloads Shared Function ChangeFromHBitmap( _ 
   ByVal hbitmap As IntPtr, _ 
   ByVal hpalette As IntPtr _ 
) As RasterImage

public: 
static RasterImage^ ChangeFromHBitmap(  
   IntPtr hbitmap, 
   IntPtr hpalette 
)

Parameters

hbitmap
Handle to the DDB to be changed.

hpalette
Handle to the palette. This value can be IntPtr.Zero if the hbitmap parameter refers to a bitmap that is greater than 8 bits, or if the bitmap will use the system palette.

Return Value

The newly created Leadtools.RasterImage object.

Remarks

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