Identify empty space in a pdf file that contains drawings inorder to stamp


I am trying to stamp PDF file which contains drawings. In order to do that I need to identify empty space to place the stamp.

Size of the drawings are not consistent and may require to resize the stamp in order to accommodate in the empty space.

What is the way to identify the empty spaces?

Hi @rbhattac

Check this

String.isEmptyOrNull(variable name) or String.IsNullOrEmpty(variable name)
