Parameters

L_HWND hWnd

Handle to the active window.

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle referencing the bitmap to be copied.

L_UINT uFlags

Indicates how image data is placed on the clipboard. You can use a bitwise OR ( | ) to pass more than one value. Valid values are:

COPY2CB_DIB	[0x0002] Copy DIB data to the clipboard.
COPY2CB_DDB	[0x0004] Copy DDB data to the clipboard.
COPY2CB_PALETTE	[0x0008] Copy palette data to the clipboard.
COPY2CB_RGN	[0x0010] Copy the bitmap's region to the clipboard.

If you specify all of the values it is the same as using the L_CopyToClipboard function.

Example

This example loads a bitmap, copies only the DIB data to the clipboard, and deletes the original bitmap.

L_INT CopyToClipboardExample(L_HWND hWnd) 
{ 
   L_INT nRet; 
   BITMAPHANDLE LeadBitmap;   /* Bitmap handle for the image */ 
 
   /* Load a bitmap, keeping its own bits per pixel */ 
   nRet = L_LoadBitmap (MAKE_IMAGE_PATH(TEXT("ImageProcessingDemo\\Image3.cmp")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL); 
   if(nRet != SUCCESS) 
      return nRet; 
   /* Copy the bitmap to the clipboard */ 
   nRet = L_CopyToClipboard (hWnd, &LeadBitmap, COPY2CB_EMPTY | COPY2CB_DIB); 
   if(nRet != SUCCESS) 
      return nRet; 
   /* Delete the original bitmap, leaving the copy in the clipboard */ 
   L_FreeBitmap(&LeadBitmap); 
   return SUCCESS; 
}
