Hi Azeddine,
We have checked using the saveAsBlob method after adding the ink annotation in the Selection Mode. We were unable to reproduce the reported issue. We have shared the sample and video for your reference.
Could you kindly try the sample and revert us whether you are facing the same issue? If yes, kindly share the video demonstration for replicating the issue. It will be helpful for us to investigate further and provide the details at the earliest.
Regards,
Dhivya.
