TImageEnView.OnImageLoaded

Declaration

property OnImageLoaded: TNotifyEvent;

Description

Occurs whenever an image has been loaded (e.g. using TImageEnView.IO.LoadFromFile.
OnImageLoaded is useful to update your UI when you are loading asynchronously.

Note:
◼When loading completes OnImageLoaded and OnFinishWork will both fire
◼To get the filename of the loaded image, use Filename
◼This event is the same as ieftAfterLoad in OnIONotify

Example

// Load images in background thread
procedure TMainForm.btnLoadClick(Sender: TObject);
begin
  ImageEnView1.AsyncLoading := True;
  ImageEnView1.IO.LoadFromFile( IEFolderMView.SelectedFilename );
end;

// Update the UI
procedure TMainForm.ImageEnView1ImageLoaded(Sender: TObject);
begin
  lblFN.Caption  := Format( 'Filename: %s', [ ExtractFilename( ImageEnView1.IO.Params.FileName )]);
  lblIdx.Caption := Format( 'Image Number: %d', [ ImageEnView1.IO.Params.ImageIndex + 1 ]);
  lblDim.Caption := Format( 'Size: %d x %d px', [ ImageEnView1.IEBitmap.Width, ImageEnView1.IEBitmap.Height ]);
end;
