------- Additional Comments From xerox_xerox2000@yahoo.co.uk 2005-24-07 02:38 ------- hi, i wonder if this bug really makes a difference for using your program; a quick lookup on msdn says wFlags == 0x00001000 == "DDF_HALFTONE: Always dithers the DIB to a standard palette regardless of the palette of the DIB. If your application uses the DrawDibBegin function, set this value in DrawDibBegin rather than in DrawDibDraw." So i would guess you would only see a slightly change in colours if this would be implemented. If your only goal is to get rid of the errormessages, you could always try to use native msvfw32.dll: WINEDLLOVERRIDES="msvfw32=n" wine program.exe and see if it really makes a difference (of course you have to put a native msvfw32.dll in ~/.wine/drive_c/windows/system)
