Need to provide support for adding UI Container to a desired location in PDF document using our EJ2 PDF viewer control.
1) Should allow the user to add/remove UI Container from the PDF viewer control.
2) Should make the container to react based on the zoom and scroll of the PDF viewer control.
3) Should allow the user to perform undo, redo based on the container added to the PDF viewer control.
4) If the UI Container is a part of the PDF element then we need to embed the same to the PDF document by saving using Pdfium library.
Note: we can host any UI elements with in this container and it will converted into image before writing with in the PDF document.
For example let consider to add stamp annotation with description , date modified details with in pdf document we need to host this with in the UI container and it will be inserted into PDF Document
