Adding Ink Annotation.

Hi,
I am trying to add ink annotation to a file as:
1- Select Ink tool.
2- Tap on page and move just few pixels say 4.
3- Annotation is added(annotation count is increased by one), but it is not visible in the page.

My question is that Why the annotation is not visible in the page?
I want that such Ink annotations must not be added to the page OR if it is added, then it must be visible(to select it) .
Please propose any solution ASAP.
Thanks.

after ink added, you need render the page again.

I am also rendering the page and it is working if I draw a long line, It only fails when I try to draw a dot or a very little line.

it is checked, if too short ink added to page will ignored.

Ok, if it is ignored, then why does it increases annotation count?

What is the status guys.
