I'm looking for an automated solution (application, tool, script...) to the following problem.
I've got multiple PDF files and for each file I want to put a footer on the first page of the document. I do not possess the original sourcecode.
The footer consists of two parts. The left side should be some text with a clickable URL and the right side should be an image.
Both parts should be scaled dynamically in relation to the corresponding format of the document.
The URL is unique for each document and should contain the filename. e.g. www.example.com/;
If possible the URL itself should not be searchable in the document.
The version of the PDF is 1.4 (PDF/A-1a)
I've used LaTeX to create documents and presentation before but never thought about processing multiple files to modify them, so do you think its possible at all and if so, can you give me a hint?
