Hi!
Is there an way to load a small thumbnail image from a large image file? I want to populate IE multi-view with small thumbs from lot of large images, now I have to load the image in full size then resize it to thumb size (200x200). Many software have superfast thumb load of thumbs when browsing a dir.
Using IE 4.3.1

Regards,

Set the TImageEnMView.StoreType property to ietThumb and thumbnails will be created from the original images. To display the original image in TImageEnView or TImageEnVect:

procedure TForm1.ImageEnMView1ImageSelect(Sender: TObject; idx: Integer);
begin
  { Display the image in ImageEnView. }
  ImageEnView1.IO.LoadFromFile(ImageEnMView1.MIO.Params[iIndex].FileName);
end;

Hi

As Bill has mentioned, use ietThumb of ietFastThumb and TImageEnMView will automatically load and resize the images using the fastest possible method.

Note: Significant speed can be gained using TImageEnMView.EnableLoadEXIFThumbnails. Though I am not a big fan of EXIF thumbnails, which can be quite variable in quality.
