Hi,
What do you recommend for this scenario?
1. I have images of a book stored in a folder that are named the same as the page number.
2. I want the user to mark areas on the page (either arrow shape, rectangle shape or annotations).
3. The program should save these shapes/annotations in a table.
4. The shapes will be reloaded the next time the same page viewed.
Is there a sample code to do that? Which component should I use (View/Vect)? How can collect all shapes and annotations and save them in a field?

Hi Waheed,
Firstly, you should use the TIELayers of TImageEnView, as it is much better than the older TImageEnVect functionality.
The three main ways to store image annotations (separately from the image):
- In a database
- As a file (e.g. with the same name as the page file)
- Embedded in the meta data of the page image (need to be JPEG or TIFF)
As the page images themselves are not stored in a database, I don't see a good reason to store the image annotations there (though you may have other reasons I don't know about). So my preference would be to save them as an file with the same name as the image, e.g.
Page_001.jpg
Page_001.ien
Saving and loading annotations from a file is simple, though as you are storing the background image separately, see the examples at:
