How to create or edit a dynamic PDF stamp

Create stamp

There are two type of stamps:

• Static stamps – it can be any PNG image. It is not possible to use “user” and “date” macro there.
• Dynamic stamps – it is vector graphic PDF. This can contain macros.

A PDF editing program is required to create a dynamic stamp (e.g. Perfect PDF 8 or Adobe Acrobat). In this program we can draw stamp layout. Macros should be placed in the texbox.

At the moment there are only two macros: &user, &date.

&date macro can contain a “date formatting” string (e.g. &date[m/d/Y])

Here is the list of possible options that can be used in “date formatting” string:

• d – current day
• m – current month
• Y – current year (4 digits)
• y – current year (2 digits)
• H – current hour (24 hour format)
• I – current hour (12 hour format)
• M – current minute
• S – current second
• p – (AM/PM)
