Hi Nigel

With below code I can open some images.

if OpenImageEnDialog1.Execute then
ImageEnView1.IO.LoadFromFile(OpenImageEnDialog1.FileName);

With below code I can encrypt images and save in folder 'Crypted_Photo'.
ImageEnView1.Proc.Encrypt (Edit1.Text, ieeaTEA2);
ImageEnView1.IO.SaveToFile('c:\Crypted_Photo\crypted1.bmp');

I know which I can Decrypt images with below code.
ImageEnView1.Proc.Decrypt (Edit1.Text, ieeaTEA2);


Can I Decrypt and show immediately all images of folder 'Crypted_Photo' with ImageenMView?
ImageenMView with bulid-in (internally option) property for Decrypt is very useful and very nice!



Best Regards

Hi Ali

There are two ways to handle this:

- Preloading

Load each image into a TIEBitmap, decrypt it, then add to your TImageEnMView


- On-Demand

Virtually fill the TImageEnMView by setting the ImageID, then load and convert the image as necessary in the OnImageIDRequestEx event:
