blocks/starter_block

 *

 * Block starter:

 * Import a PDF page containing blocks and fill text and image

 * blocks with some data. For each addressee of the simulated

 * mailing a separate page with personalized information is

 * generated.

 * A real-world application would of course fill the blocks with data

 * retrieved from some external data source.

 *

 * Required software: PPS 8 or above

 * Required data: input PDF, image
