How to use the Stamp feature?

How do I use the stamping feature?

1. Is there a menu item in the demo to enable it?

2. You have some predefined values in Page_addAnnotStamp. How does that work?

3. Can the user touch any area of the page and drop a stamp there? If so how do I implement this programmatically? Any sample code available?

4. Why would you not simply add this in the demo app so we can visualize how this weeks and see sample code instead of asking all this in the forum?

5. What about the storage strategy and management of files, annotations, annotated PDF files? Where are they stored?

we have no UI for predefined stamp annotation. it has too many types.
and need too many images to display on menu.

added annotation save in memories first, and save to file when Document.Save() Invoked.

to check this feature, u can replace Page.AddAnnotBitmap to Page.AddAnnotStamp simply.

Thank you for your reply. I also tried the text annotation in your demo but it doesn't seem to work. Is this a bug? There is just no way to tap on an area of the screen and enter text.

after added note annotation, u can tapped on note icon.
demo shall pop a toolbar, plz click on second button (button image has 5 lines).

Your text annotation simply does not work. It is frustrating to want to buy a software like this and you can't even demo all the features. This is the hardest pdf framework I have ever tried where you have to do so much in code instead of having a clean working API.

You should be able to provide a demo with all the features in working conditions.
You should be able to provide clean Apis
You should be able to provide sample codes so that one doesn't have much coding to do just to add features that were supposed to be provided.

I have spent hours evaluating this and I am still unsure if I am going to be satisfied with the product because I can't even see it working as I expect and I have to invest time in coding just to see if it is going to work.

Hi,
to check the note annot, you have to long press the pdf text, then highlight the part that you want to note, release the finger and check the note option (TA: text annot).
In the video, you are trying to show the pdf index, but the demo pdf doesn't have one.
