I've tried to make script which replaces all entries of WORD (f.e. "bla") to WORD2 (f.e. "ble"), without font-formatting change (e.g. if WORD was Tahoma-italic, WORD2 need to be Tahoma-italic too).

And I can't fully understand structure of PDFedit model.

Could you plaese help me with simple sample of such script?

Thank you! (:

PS: As a bonus :) it'll be great if you show how to change font of some word (also I need to markup text with some rgb background; and change font color to transparent or white). Thanks again! :D
