Subject: Demo Limitations?

I'm evaluating the Envision library for a project working with very large B/W Tiff G4 iamges. These files may be 10,000 or more pixels high by 2,000 or more wide. They consist of a horizontal and vertical grid with several curves. The problem is to view the entire image on the screen and still be able to see the curves.

Working with the TImageScrollBox I can use the Sharpen transform and see a noticeable improvement. If I just run the Sharpen transform on the graphic and save it there is very little difference. Is this a limitation of the demo version or do I need to use the TImageScrollbox to see these changes?

Here's the code I'm using for the offscreen sharpening:

procedure TForm1.Sharpen2Click(Sender: TObject);
var
tif : TTiffGraphic ;
shrp : TSharpenTransform ;
begin

if OpenDlg.Execute and SaveDlg.Execute then begin
tif := TTiffGraphic.Create ;
tif.LoadFromFile ( OpenDlg.FileName ) ;
shrp := TSharpenTransform.Create ;
shrp.Apply ( tif ) ;
shrp.Free ;
tif.SaveToFile ( SaveDlg.FileName ) ;
tif.Free ;
end ;
end;

Mitch
