A script solution requested: conversion from text-only pdf to pagewise image files

[Ofnuts]

Is the text real text (PDF produced as output of word processor) or just a bitmap image of text (scanner output). In the first case, don't use Gimp, use a real PDF editor (LibreOffice Writer can do things, IIRC).

"Low resolution" is just metadata, do you mean to also scale the ilage down?

If you have only one image to process, you can:

• Load it in Gimp wit the appropriate options (one layer, per page, transparency, maybe even the right definition)
  
• Scale it down & change the print definition (if not done in previous step)
  
• Run a script to export all the layers individually (see for instance ofn-export-layers)
