Turns out I'd not simplied too much as the above solution works (needs one extra close parenthesis). THANK YOU. I wasn't trying to argue, rather I had no idea what syntax I needed to implement Hans' suggestion. strcol(1) was what I needed to know. I am curious why I can't just do "using 1:2", i.e why when doing it this spits (1) out as %f with exponent.

No, I've not simplied too much at all. The above solution works (needs one extra close parenthesis). I wasn't trying to argue, I had no idea what syntax I needed. The strcol(1) was what I needed.

It shouldn't hang. I didn't pick that syntax out of choice, I can't get any of the simpler options to work. It's a 10 line example. with a provided input file. If you have a solution can you paste a similar number of lines that show what you're suggesting? The goal is to write out a temp table which has the time/date in the same "%B %d %Y" format so the temp table can be processed by a subsequent plot command. Just doing "using 1:2" doesn't work as the time is written out as %f. Specifying "set format...

There seem to be some issues with hpw the text is formatted in the above. Here is tarball of the files.

strftime goes into infinite loop as internal rep is NaN

I tried using scantailor. I noticed it's not really maintained. Last update was several years ago. a) it's much harder to use than NAPS b) the image quality is badly affected by the transformations as you can see in the attached. For pages that contain a lot of greyscale already, there isn't much size expansion after NAPS deskews and the quality is very good compared to the original. It's just the simpler pages containing b/w elements that suffer a size expansion. When I get some time I'll try digging...

I see. Thanks for the clarification.

Also, I'm not sure the comment "is that you start with a two-tone image (black and white only)." is true. If you look closely at 006 and 111 the hole punches for example are greyscale in both images. Obviously preserving the nature of the holes in paper isn't anything I much care about, I was just pointing out that these are not b/w images. OTOH maybe I'm not understanding something.
