I have one button upload sign on my page and if we click on that it call one microflow which commit personalSign object and shows image on page   and I have one generate document button if I click on that button then it generate document , I have document template in my project which shows data over document .

Is the PersonSign entity a specialization of System.Image?  If so, when you place the Dynamic Image Viewer in the document template, look at the properties of the Dynamic Image Viewer.  In the properties you will have the ability to select the entity for the Dynamic Image Viewer.  You should select PersonSign.

If PersonSign is not a specialization of System.Image, you will need to make it a specialization of System.Image.
