I extracted the pdftoppm program from your link, set it up as best I can, changed one default parameter

OK now this forewarns me that something bad is going to happen...

- so it would create a pgm file instead of a ppm file

the '-gray' switch should take care of that, I think.

- and gave it a go. That might be the source of subsequent problems with pi-exe, but it didn't prevent pdftoppm from doing it's thing.
The program created 52 pgm files from the pdf I'm using for testing purposes. While that's a lot, it's the one type of pdf I know I'm gonna need to convert monthly, so I figured I'd see what happened.
Took one of those 52 files, and did the "pi X.pgm Y" thing,

you did mean 'pi X.pgm Y.pgm'?

Yes, this is what is referred to in this thread as a segmentation fault. It basically is the program's way of crashing.

All this means is that the .pdf is too low in resolution, or has a non-white background, or the 'white-gaps' between lines are not easily detectable. In otherwords, your .pdf cannot be converted by version 0.1 "as is".

As far as I know, I'm not using the 0.2 version, that you cautioned about (though who knows? Anything's possible wit Da Idiot in Da House.)
Looking forward to your reply. Thank you!

Yes, you don't have version 0.2 as no-one has that one working yet!
