Summary

Syntax
public static Leadtools.RasterImage ChangeFromHBitmap(IntPtr hdc,IntPtr hbitmap,IntPtr hpalette)
Public Overloads Shared Function ChangeFromHBitmap( _ByVal hdc As IntPtr, _ByVal hbitmap As IntPtr, _ByVal hpalette As IntPtr _) As Leadtools.RasterImage
public:static Leadtools.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 MMTEXT.
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.
For more information on DDBs and DIBs, refer to Using DIBs, DDBs, and the Clipboard.
