In the past I've used Inkscape in a bash script to replace a word for a list of names, doing the credentials creation progress very efficient (from 5h to 1h). I wanted to know if it's possible to remove the same picture that appears in all the pages of a PDF without manually opening them with Inkscape.

The picture in the XML editor seems to have these characteristics: id=26, image id=image28, matrix(1,0,0,-1,0,1)
