Hi, I'm having problem to get the image dimensions do ImageEnMView, using the "FillFromDirectory". I am using the following code in version 4.1.0:

ImageEnMView1.FillFromDirectory(sfDialogoTodas.SelectedPathName);
for idx := 0 to ImageEnMView1.ImageCount - 1 do
begin
ImageEnMView1.ImageTopText[idx].Caption := 'Imagem ' + inttostr(idx);
ImageEnMView1.ImageInfoText[idx].Caption := inttostr(ImageEnMView1.ImageWidth[idx]) + ' x ' + inttostr(ImageEnMView1.ImageHeight[idx]);
end;


If I load the image with the "LoadFromFile", the above code works correctly. There is another alternative to the above code to use with "FillFromDirectory"?

When using FillFromDirectory try setting the captions in BeforeImageDraw:

procedure TForm1.ImageEnMView1BeforeImageDraw(Sender: TObject; idx, Left,
  Top: Integer; Canvas: TCanvas);
begin
  ImageEnMView1.ImageTopText[idx].Caption := 'Image ' + inttostr(idx);
  ImageEnMView1.ImageInfoText[idx].Caption := inttostr 
    (ImageEnMView1.ImageOriginalWidth[idx]) + ' x ' + inttostr
    (ImageEnMView1.ImageOriginalWidth[idx]);
end;


When you set the captions right after calling FillFromDirectory not all of the images are loaded yet.
