Create Pdf from Pdf Template.

Question

Hi,

I have scenario, where i have to create pdf documents from pdf templates + data from database.

I know about some open source pdf generating componets. but I can't find way/example to create pdf from a pdf template.

I will have to  read pdf template, replace tags(tags used to mark editable area) with data from  database then save generated pdf to disk.

Please provide samples/resources to acquire this task.

Regards,
Azam.
