Hi Jodeye,

I have done a recent change to support that and this will official be included in version 2.

If you need this immediately you'll need to add this method to TDibGraphic:


procedure TDibGraphic.Fill( const Color : TRgb );
var
X : LongInt;
Y : LongInt;
begin
if IsEmpty then
Exit;

{ Fill the first scan line, then copy the scan line to all other lines }
for X := 0 to (Self.Width-1) do
Self.Rgb[ X, 0 ] := Color;

for Y := 1 to (Self.Height-1) do
Move( Self.ScanLine[0]^, Self.ScanLine[Y]^, Self.ScanLineSize );
end;

and add a BackgroundColor property to TMetaFileGraphic:

{ background color used when loading the metafile }
property BackgroundColor : TRgb read FBackgroundColor
write FBackgroundColor;

then in TMetaFileGraphic.SingleLoadFromStream add,

{ MB Dec 18, 2001. Use the background color specified by the user }
Self.Fill( FBackgroundColor );


just after NewImage.

Best regards,

Michel
