I discovered a PDF (version 9 acrobat?) that wouldn't work properly in the Kobo Sage or Kobo Elipsa Crop. Also on Kobo you could only change page using the naviagtion slider, neither tap, swipe or buttons would change page. Actual text, so I might convert to epub if I can export it sensibly. It does import to LO Draw, but using that to format other than paper size or margins is tedious.

Anyhow, cropping it before importing to Calibre sorted it, though it got a little larger. After crop you could page through it.

It's not OCR text, but just text. A copy and paste in any desktop program does give the text in the right order, but each line break in PDF is a new line and so it can't be reflowed, the paragraph breaks same as newlines.

Can K2pdfopt export the text with only newline at paragraphs rather than the end of every line in the PDF? It's not an OCR layer, but only text.

Adding asciidoc or markdown markup should be almost trivial. Then newlines are ignored except for empty lines, which indicate a new paragraph.

Extremely long lines are editor unfriendly and are annoying, so I actually prefer text exports that haven't stripped newlines.

The information I get about a PDF file from the muPDF library is simply a list of characters and what their X,Y positions on the page are. There is no information to indicate either new-line or a paragraph--you have to infer this solely from the character positions, so I'd have to deduce from the line spacings or indentation if a paragraph was indended, which will be quite error prone. It's probably easier to hand edit the unicode text out of k2pdfopt (-ocrout option).

Paragraphs have either more indent or more space or start with a bolded word (all caps too usually) or are numbered list items. Only the ALL CAPS and list numbers survive text copy.

Rats. PDFs are evil to do anything with except print or read on a giant screen

Actually the k2pdfout with -ocrout option put two newlines at paragraph breaks, but I'd only got one with a copy/paste.

So replaced all \n\n with ¬
replaced all \n with a "space"
replaced ¬ with \n

(But I wasn't using Windows notepad )

Now only needs a day's work to make into an epub. Almost looks sane in LO Writer.

Only 20 minutes ago finished major edit/format/style in LO Writer and conversion of extra docx save in Calibre to epub2.

Still, beats typing it up from looking at the paperback!

I'm having problems downloading and installing k2pdfopt. I'm using a mac but the download always stalls, I click re-load and it downloads but when I install it I get the following:
Last login: Mon Mar 6 16:54:47 on ttys000
Davids-MacBook-Air:~ david$ /Users/david/Desktop/k2pdfopt ; exit;
/Users/david/Desktop/k2pdfopt: line 1: syntax error near unexpected token `<'
/Users/david/Desktop/k2pdfopt: line 1: `<html><head><title>Willus.com's K2pdfopt Download Page</title>'
logout
Saving session...
...copying shared history...
...saving history...truncating history files...
...completed.

[Process completed]

Any suggestions?

I am wondering if k2pdfopt isn't downloading properly as I have to reload it or whether it isn't running correctly. I'm not sure what the syntax error near the unexpected token ' <' meant and how I could correct it?

I'd be very grateful for any suggestions or advice as k2pdfopt looks exactly what I'm looking for and there doesn't seem to be anything better as far as I can find.

Many thanks in anticipation.

You're downloading a source code of the download page, not the program.
The first line of the source page reads:
<html><head><title>Willus.com's K2pdfopt Download Page</title>
Fill in the captcha and click on the relevant software (v2.54 mac OSX x86 64-bit ?).

Thanks for explaining that. One step closer! However I am clicking on the relevant software and that what is downloading so I'm not quite sure what is going on. Very frustrating.

It seems you have to right click on the rectangle (e.g. Mac OSX...) or control-click (when on Mac) on the rectangle and then select Save as... which saves the page, not the program.
Or try a different browser or wait till Willus responds.

Great! Good idea - I think a different browser might be better. I was wondering if perhaps the captcha is timing out before the download has fully completed? I'll try your suggestions - Thanks.
