Muy buenas, alguien me sabria decir donde puedo encontrar la funcion PrepareInfoHeader al compilar este ejemplo me da error de no encontrar dicha funcion:
pragma BEGINDUMP
include <windows.h>
include <hbapi.h>
BITMAPINFOHEADER PrepareInfoHeader( WORD, WORD );
HBITMAP FWWaterMark( HBITMAP hbm )
{
BITMAPINFOHEADER bmiS, bmiD;
LPBITMAPINFOHEADER lpSrcBits, lpDesBits;
DWORD dwSizeScr;
HANDLE hDibSrc;
HDC dc, dcDes;
BITMAP bm;
HBITMAP hbmDes, hbmOldDes;
INT j,i;
GetObject( hbm, sizeof( BITMAP ), &bm );
// source
bmiS = PrepareInfoHeader( ( WORD ) bm.bmWidth, ( WORD ) bm.bmHeight );
dwSizeScr = ( ( bm.bmWidth * bmiS.biBitCount + 31 ) / 32 ) * 4 * bm.bmHeight;
hDibSrc = GlobalAlloc( GHND, dwSizeScr + sizeof( BITMAPINFOHEADER ) );
lpSrcBits = ( LPBITMAPINFOHEADER )GlobalLock( hDibSrc );
*lpSrcBits = bmiS;
dc = GetDC ((HWND) NULL);
GetDIBits( dc, hbm, 0,
( UINT ) bm.bmHeight,
lpSrcBits,
( LPBITMAPINFO )lpSrcBits, DIB_RGB_COLORS);
dcDes = CreateCompatibleDC( NULL );
bmiD = PrepareInfoHeader( ( WORD ) bm.bmWidth, ( WORD ) bm.bmHeight );
hbmDes = CreateDIBSection ( dc, ( LPBITMAPINFO )&bmiD,
DIB_RGB_COLORS, ( void ** )&lpDesBits, 0, 0 );
hbmOldDes = SelectObject( dcDes, hbmDes );
for( j = 0; j < bm.bmHeight; ++j )
{
LPBYTE pbDestRGB = ( LPBYTE )&( ( DWORD * ) lpDesBits )[ j * bm.bmWidth ];
LPBYTE pbSrcRGB = ( LPBYTE )&( ( DWORD * ) lpSrcBits )[ j * bm.bmWidth ];
for( i = 0; i < bm.bmWidth; ++i )
{
pbDestRGB[ 0 ] = pbSrcRGB[ 0 ];
pbDestRGB[ 1 ] = pbSrcRGB[ 1 ];
pbDestRGB[ 2 ] = pbSrcRGB[ 2 ];
pbDestRGB[ 3 ] = 255;
pbDestRGB += 4;
pbSrcRGB += 4;
}
}
SelectObject( dcDes, hbmOldDes );
GlobalUnlock( hDibSrc );
GlobalFree( hDibSrc );
DeleteDC( dcDes );
DeleteObject( hDibSrc );
ReleaseDC ((HWND) NULL, dc);
return hbmDes;
}
HB_FUNC( FWWATERMARK )
{
hb_retnl( ( LONG ) FWWaterMark( ( HBITMAP ) hb_parnl( 1 ) ) ) ;
}
