How do I change 256 color palette that user make the 256 color palette

hi

I want to change 256 color bmp file from all bmp files. also want to apply user 256 color palette.

I tested with LeadTools.

=================Tested Source Start ============================

LPLOGPALETTE pLogPalette = (LPLOGPALETTE) malloc( sizeof( LOGPALETTE ) + sizeof( PALETTEENTRY ) * 255 );
if( NULL != pLogPalette  )
{
    pLogPalette->palVersion    = 0x300;
    pLogPalette->palNumEntries = 256;
    for( L_INT16 i = 0 ; i < pLogPalette->palNumEntries ; i++ )
    {
        pLogPalette->palPalEntry[ i ].peRed   = GetRValue( pList->GetItemData( k ) );
        pLogPalette->palPalEntry[ i ].peGreen = GetGValue( pList->GetItemData( k ) );
        pLogPalette->palPalEntry[ i ].peBlue  = GetBValue( pList->GetItemData( k ) );
        pLogPalette->palPalEntry[ i ].peFlags = 0;
      }

      HPALETTE hPalette = CreatePalette( pLogPalette );

      LBitmapBase BitmapBase;
      BitmapBase.Load("C:\temp\test.bmp");      // 'test.bmp' is 24bit color bmp file
      BitmapBase.SetPalette(hPalette);
      BitmapBase.Save(FILE_BMP, 8, 2);         // Not apply to user 256 color palette

      DeleteObject( hPalette );

}

free( pLogPalette );

=================Tested Source End ============================

How can I change user 256 color palette?

Please help me.

 

To use your custom palette use L_ColorResBitmap, This function provides flexibility in specifying the output destination and in specifying the palette to use.

For more information, please refer to L_ ColorResBitmap in the Main API help file.
