GuessGame Demo Fails To Compile - Tokyo

Recommended Posts

Many Demos use the pngimage.pas file making them non-compileable.

 

{Copy interlaced images with 1 byte for R, G, B}

procedure TChunkIDAT.CopyInterlacedRGB8(const Pass: Byte;

  Src, Dest, Trans{$IFDEF Store16bits}, Extra{$ENDIF}: pChar);

var

  Col: Integer;

begin

  {Get first column and enter in loop}

  Col := ColumnStart[Pass];

  Dest := pChar(Longint(Dest) + Col * 3);

  repeat

    {Copy this row}

    Byte(Dest^) := fOwner.GammaTable[pByte(Longint(Src) + 2)^]; inc(Dest);

    Byte(Dest^) := fOwner.GammaTable[pByte(Longint(Src) + 1)^]; inc(Dest);

    Byte(Dest^) := fOwner.GammaTable[pByte(Longint(Src)    )^]; inc(Dest);

 

    {Move to next column}

    inc(Src, 3);

    inc(Dest, ColumnIncrement[Pass] * 3 - 3);

    inc(Col, ColumnIncrement[Pass]);

  until Col >= ImageWidth;

end;
