Subject: ResizeTransform Question

Hi All ~

am new to Envision (even though we bought it two years ago):

For the snippet below: isb is an ImageScrollBox (just dropped on form - no changes made but to its name) and Pic
is a TPicture.

Any suggestion as to why the code below does not produce the desired result, i.e. a stretchdrawn copy of the image from Pic on isb?

procedure Tform1.StretchDraw(SrcGraphic, DstGraphic: TDIBGraphic; const DstWidth, DstHeight: Integer);
StrDrawTransform: TResizeTransform;

// ifTriangle, ifHermite, ifBell, ifBSpline, ifLanczos3, ifMitchell
StrDrawTransform := TResizeTransform.Create;
StrDrawTransform.Interpolated := True;
StrDrawTransform.Filter := ifTriangle;
StrDrawTransform.Height := DstHeight;
StrDrawTransform.Width := DstWidth;
StrDrawTransform.ApplyOnDest( SrcGraphic, DstGraphic);

procedure TForm1.Button2Click(Sender: TObject);
StretchDraw( Pic.Graphic as TDIBGraphic, isb.Graphic, isb.Width, isb.Height);
