In this article, I will show you how to add new layer to PDF either by image layer or text layer which can be hidden casually. I use the tool VeryPDF PDF Stamp Command Line, which is an professional application to stamp PDF through command line. However, if you would like to use GUI version, there is also one available for you.
Step 1. Get One copy of PDF Stamp Command Line
- Please download this Window application to your computer then unzip it. The executable file is kept in subfolder example.
- Also in the example folder, there are many bat files which allow you check the stamping effect by simply clicking.
Step 2. Add Layer to PDF
- When you use this software, please pay more attention to the syntax as it is a little complicated for its powerful functions.
Usage:pdfstamp.exe
[<-PDF> <file> [-O <file>] ]
[<-AT> <string> [-Pn] [-MLRn] [-MTBn] [-Rn] [-L]—>those parameters are for stamping text stamp
[<-AI> <string> [-Pn] [-MLRn] [-MTBn] [-Rn] [-L]—> those parameters are for stamping image stamp
