    TColor and dxDraw1.Surface.Fill

    Hi ho again guys

    Whats the story regarding dxdraw and color allocation??

    If I use a standard TColor value in the form of say
    var back_col: TColor;

    back_col := $00XXXXXX; // ( some desired color)
    dxDraw1.Surface.Fill(back_col);

    then it does not display the correct color

    I have tried setting the high order byte to the various values allowed such as 00 or 01 or 02 ...

    am using a 800 X 600 screen and have tried the different color resolutions like 16 and 24

    anyway the desired action is to be able to set the background to a particular desired color.... How ??

    cheeeeeeeeeeerrrrrrrrrssssssssssss ato

    Hola!

    You need to use the DXDraw.Surface.ColorMatch function to convert the TColor value to the value used by DirectDraw.
    [pascal]DXDraw.Surface.Fill(DXDraw.Surface.ColorMatch(back _col));[/pascal]
    However, the ColorMatch method is quite slow IIRC, so you might find it better to do the conversion only once and store it until required.
